Why doesn't the injection gazelle 405 start? main reasons

There are different problems with cars, but for some reason the Gazelle 405 injector does not start most often. Drivers begin to rack their brains, but sometimes a solution to the problem is still impossible to find.

Now we will look at several of the most likely breakdowns during which the car will not start.

When this happens, you first need to look at all the wires, spark plugs, rail pressure and injectors. Most often, the Gazelle 405 injector does not start because of the spark plugs, so just replace them. But sometimes problems arise that are more serious than candles.

Ignition system

Spark plugs and high-voltage wires directly affect engine starting. Accordingly, breakdowns in the elements will cause a failure of the entire system. To check spark plugs, a special stand is used, although you can check it the old fashioned way:

1. We unscrew the candle from the well.
2. We connect the armored wire.
3. Connect the spark plug body to ground.
4. We try to start the engine.

If everything is in order with the spark plugs, then there will be a spark between the contacts. If the part is faulty, then there will be no spark, and accordingly, the element must be replaced. Checking armored wires is quite simple. All elements are removed from the car and measured by a tester. The resistance on each high voltage wire should be 5 ohms.

Fuel cells

Why won't my scooter start?
causes and possible breakdowns It is worth understanding that almost all elements affect the start of the motor. For example, since the Gazelle was produced both with carburetor and injection, the injection elements will be different. This means that the reasons for possible breakdowns will not be the same.

The Gazelle-406 engine is an injection version of the vehicle. It has injectors installed, which can be the source of the problem. If cleaning has not been carried out, then most likely the injectors are dirty. To fix this, you need to remove the parts from the machine and send them for cleaning. If, during the process of restoring the functionality of the injectors, it turns out that the product cannot be repaired, then it must be replaced.

A fuel pump malfunction may be due to a breakdown inside the module. To check whether the pump is pumping, you need to get behind the wheel of the car and turn the ignition key to the second position. In this case, a characteristic noise should begin from behind, which will mean that the pump is in working condition.

Particular attention should be paid to the condition of the fuel filter. According to the service manuals and recommendations of the manufacturer, the fuel filter element must be changed every 40,000 km.

If this is not done, the filter becomes clogged and does not allow fuel to pass through properly, which results in a lean mixture in the cylinders, or gasoline does not get in for ignition at all.

Try pumping it up three times and starting it! 1 temperature sensor 2 pump is dying!

Try starting it with the gas pedal depressed. To be honest, there can be many reasons: injectors (flow), pump (pressure), jot (new, it’s not a fact that it’s working or not for your brain www.drive2.ru/l/5303392/), ignition angle, quality of gasoline, rxx ( try flushing), voltage on board (try to throw a wire on the coil with the + battery when it’s cold and start it like that, when you connect the ignition will turn on, that’s how it should be!), spark plugs (gap of spark plugs), air filter (unlikely, but still) , timing belt (stretched chain), try wiping the headlights before starting))) (HUMOR), maybe I missed something else, someone will add!

Thank you for your response, everything that you listed this year, everything was installed new, you understand, the mileage is 356,000 km... it starts but not the first time, the second or even the third... on a warm engine with half a turn... by the way, what kind of OZ should Mikasa 11 have? The ZMZ 405 won't start at all with the pedal depressed! If the forces were flowing when the ignition was turned on, popping noises would be made in the combustion chambers! this is not the case. Idle speed is perfect 800 rpm. Most likely the DTOZh stuck the wrong one!

On Mikasa I can’t say, it seems to be programmed there from the factory because it doesn’t change the advance angle from the onboard one. But on Soate it changes for me. Try to play around with the camshaft sensor, it also sometimes gets weird and there is no way to check it and it won’t give an error until it shorts out, it was like seven years ago, at idle there seemed to be little shaking and every other time it started normally, who knows? . you can check its integrity through resistance with a cartoon just like a jot, but I don’t remember the parameters ((, a guy suggested it a long time ago, since they are not exchangeable, he checked it right away from the cash register, out of 10 only 5-6 are normal .

Thank you for your response, everything that you listed this year, everything was installed new, you understand, the mileage is 356,000 km... it starts but not the first time, the second or even the third... on a warm engine with half a turn... by the way, what kind of OZ should Mikasa 11 have?

Some, when the Gazelle 405 does not start, immediately change the coolant temperature sensor. The fact is that the engine may overheat and it is because of this that it does not want to start.

Try changing the sensor and the cooling will return to normal. In any case, the most reliable option is to take it to a car service center. There, qualified specialists will quickly deal with the breakdown and tell you what was wrong with the car. You will know in the future what exactly will have to be repaired.

The fuel pump does not work, the relay turns on.

Checking relay power.

The main reasons why a Calm chainsaw does not start and how to eliminate them: we explain it step by step

In the case when the fuel pump relay turns on when the ignition is turned on, but the pump itself does not work, you need to check the power at terminal 87 of the fuel pump relay. To do this, touch terminal 87 of the relay socket with the output of the control lamp connected to the vehicle ground, and the lamp should light up. If the lamp does not light, it means the fuse has blown or there is a break in the wire.

If there is power at terminal 87, you should remove the relay from the socket, and instead place a jumper between pins 87 and 30. In this case, if the pump and connecting wires are working properly, the pump should start working and if this happens, the relay should be changed. If the pump does not start working, then, without removing the jumper, you need to touch the power wire on the fuel pump with a test lamp connected to the vehicle ground.

Checking the fuel pump power circuit.

If a submersible pump is installed on the car as part of the fuel module, you need to remove the connecting connector and touch one of the thick wires. When you touch one of them, the indicator lamp should light up. If the lamp does not light up on any of the wires, then it is necessary to eliminate the break in the wire from the fuel pump relay to the module connector or the pump itself, if the pump is of a remote type. One of the reasons for the break may be the anti-theft blocking of an installed non-standard alarm system.

In the case when the test lamp lights up on one of the thick wires of the connector or one of the terminals of the remote pump, you need to connect these terminals with a test lamp to each other. In this case, the control lamp should light up. If the lamp does not light, it is necessary to eliminate a break or poor contact in the wire connecting the pump to the vehicle ground.

If, when checking the wires and relay for turning on the fuel pump, no malfunction is detected, the electric motor of the fuel pump or its connection to the module connector is faulty. It is not difficult to find the cause by removing the fuel pump module from the tank. If there is poor contact with the connector, melting of the plugs will be visible. If melting is not noticed, then to check the pump itself, you can connect it to the battery. It should be taken into account that operating a submersible pump without liquid will damage the pump. A faulty pump should be replaced.

One of the most important elements of the fuel injection system of a gasoline engine is the electric fuel pump, which is located in the fuel tank of the car. The fuel pump pumps fuel into the system from the gas tank, creating a certain pressure.

Auto repair experts identify the following common fuel system problems that are related to the fuel pump:

• The fuel pump pumps poorly and does not create the required pressure;
• the fuel pump does not pump when the ignition is turned on;

Considering that the fuel pump is an electromechanical device, the most common fuel pump malfunctions are related to both the mechanical and electrical parts. Next, we will look at what signs indicate a breakdown of the fuel pump and why the fuel pump stops pumping partially or completely.

The procedure and methods for starting an injection engine are the same at any outside temperature, but they have some differences depending on the temperature state of the engine itself. Problems with starting the ZMZ-409 engine may occur in the event of a malfunction or interruption in the operation of the following systems: starting system, ignition system or fuel injection system.

The procedure for starting the ZMZ-409 engine at an outside temperature of minus 20 degrees and above.

It is described in detail in the operating manual for the corresponding UAZ car model. When starting the engine, the control system will independently set the fuel supply and ignition parameters necessary for starting, and after it starts, it will automatically set high idle speeds and will gradually, as the engine warms up, reduce them to minimum. It is not advisable to start the engine if the electric fuel pump has not yet turned off or if the engine fault diagnostic lamp is on.

The procedure for starting the ZMZ-409 engine at an outside temperature of minus 20 degrees and below.

If the ambient temperature is below minus 20 degrees, then starting the ZMZ-409 engine without preliminary preheating of the crankcase oil and coolant is not recommended. As a last resort, before starting you need to at least warm up the engine intake receiver with warm steam or water. The starter cranking time should be no more than 10 seconds, and re-cranking is allowed no earlier than after one minute.

Battery problems

If the Gazelle does not start, then you should start searching for the impossibility of starting the engine with the battery. If it is insufficiently charged, the starter does not have enough energy to turn the crankshaft. In this case, a significant drop in the on-board network voltage occurs. The traction relay starts to click, but the engine cannot start.

ATTENTION! A completely simple way to reduce fuel consumption has been found! Don't believe me? An auto mechanic with 15 years of experience also didn’t believe it until he tried it. And now he saves 35,000 rubles a year on gasoline! Read more"

The situation with starting the engine with a discharged or old battery is aggravated in cold weather. There are two reasons for this:

• engine oil thickens in the cold and it becomes more difficult for the starter to crank the crankshaft, which causes increased starting current and greater battery energy consumption;
• When it's cold, the chemical reactions of the battery slow down and the battery becomes able to deliver less charge.

In winter, both of the above reasons overlap each other. Starting becomes especially difficult when cold. Under unfavorable conditions, the car may completely refuse to start.

With a discharged battery, many car owners start their Gazelle only with a pusher, but there are other ways, the main ones being:

• start using ROM;
• “lighting up” from another vehicle;
• charging the original battery with a nominal or increased current and then starting the power unit.

A situation with a discharged battery does not require special attention from the car owner if it occurs only once. It is enough to recharge the battery and you can continue to operate the machine as before. If the battery dies often, then it is necessary to diagnose it. Based on its results, a decision is made on the method and feasibility of restoration work. In some cases, it is more rational to purchase a new battery.

If the battery shows full serviceability, but dies in a short period of time, then the on-board network must be checked. It may contain short circuits and high leakage currents. If they are identified, you should not delay troubleshooting. Prompt resolution of problems will eliminate the risk of a car fire.

The presence of through cracks and other similar defects leads to the loss of part of the electrolyte. The battery's ability to deliver starting current and energy is significantly reduced. To diagnose the problem, just carefully inspect the case. If any damage is detected, the car owner is faced with a choice between carrying out repairs or purchasing a new power source.

Fuel injection system failures

For normal injection, the electronic control unit needs to receive and process information from several sensors in real time. Problems with the meters, communication links, or main module may cause the injector to stop working properly. Because of this, starting the engine will become significantly more difficult, even to the point of complete failure.

To solve problems with sensors, they need to be checked. It can be done indirectly using a multimeter. Car owners recommend sequentially replacing installed meters with known good ones.

If the start-up becomes normal, then the culprit of the problem is the last replaced element.

To solve problems with the electronic control unit, a diagnostic scanner is required. It should be used to count errors. After deciphering them, a decision is made on further repairs.

Signs of trouble

There are three main symptoms of problems with the injector (injector malfunction) of a Gazelle car.

A characteristic sign of a malfunction can be considered detonation, which is unpleasant for the driver’s hearing.

It destroys the motor, which is why it is so important to find the fault in time and fix it. If the engine stalls for no reason on the road, and subsequent attempts to start it lead to the goal only after many repetitions, this is a clear sign of a faulty injector. The power of the power unit does not inspire approval as before. In common parlance - the car does not “pull”

When climbing a hill, the movement turns into a real test of the driver’s nervous system and can be detrimental to the engine.

Doesn't start when the injector is hot

Bringing the car back to life

As for why a spark disappears, everything is probably very clear. Now, it would not be amiss to consider the order of her return. The reality is that in most cases, getting the spark back is a simple matter and just involves carefully checking the broken car. To be more precise, to normalize sparking it is required:

1. Firstly, check the spark on the injector using the method described above, make sure that it has disappeared, and, at least indirectly, try to determine the cause of the malfunction;
2. Next, it is enough to assess the current circumstances and act based on them. As typical situations, we suggest considering solutions to the following problems:
3. the spark plug is wet, the presence and strength of the spark are unimportant, the carbon deposits are correct (brick color) - wipe the part and screw it back in;
4. the spark plug is wet (not always) and the carbon deposits are incorrect (white or black) - clean, dry the part and try to start the engine, if there is no result, change the spark plug and deal with problems in the fuel system (cleaning the injector, checking the ECU, etc.);
5. the spark plug is wet, there is no spark at all, the color of the soot is not important - we try to change the part, if there is no result, we check the ignition system and the operation of the injector.

In principle, in theory there are no particular difficulties in repairs of this kind. Despite this, it often causes difficulties in implementation for inexperienced motorists. To solve these, you need to act in the order described above, but if something doesn’t work out, it’s better to turn to professionals at a service station. This approach to repairs will not only save time, but also guarantee trouble-free operation of the car in the future.

Perhaps this concludes the most important information on today’s issue. We hope that the material presented was useful to you and provided answers to your questions. Good luck in operating and maintaining your car!

Common Causes

The Gazelle 405 injector does not start for various reasons. There could be a hundred of them, or even more, since there are simply unrealistically many details. However, injectors and spark plugs

. If the latter can be bought at any auto parts store, and even a less experienced driver can replace them, then problems may arise with the former.

The fact is that it is very difficult to determine that in such a situation in the Gazelle 405 it was the injectors that broke

.

Malfunctions of the engine power supply system

The most popular problem among inexperienced car owners that leads to the inability to start the power unit is the end of the fuel in the fuel tank. At the same time, the indicator on the instrument panel does not always display information correctly. It is very easy to solve the situation that has arisen. You just need to refuel the Gazelle. Other problems that lead to the engine not starting can be found in the table below.

The carburetor engine stalls after warming up - what's the matter?

Carburetor power units are virtually a thing of the past. But many cars on the roads of our country still use this option to supply fuel to the engine. For many, a carburetor turns out to be a rather convenient means of replacing an injector, as the car becomes easier to repair and cheaper to operate. In most cases, the owner of a carburetor car can independently carry out basic maintenance work on the fuel system. In the case of an injector, this should only be done by a specialist. For simple carburetor repairs, no special equipment is required, and such devices are simply necessary for working with the injector. Therefore, this part of the engine fuel system has a number of advantages. Interestingly, these advantages force many to change the injector to a carburetor, which is not at all difficult.

Problems that arise with the carburetor can be very different. One of the most common problems is the engine turning off after the car has fully warmed up. The driver has to increase the revs with the intake, but this trick will not work on auto-intake carburetors. Finally, immediately after releasing the accelerator pedal, the engine stops. At every traffic light, intersection and pedestrian crossing, the driver begins to curse fate, red lights and innocent pedestrians, and the carburetor continues to stall and refuses to work normally, despite very expensive gasoline. Let us consider the nature of this inconvenience.

Why might the carburetor stall after warming up?

To understand the cause of this problem, it is best to turn to motorists who have already experienced such a nuisance. Whatever happens to your car, remember that similar problems have likely happened to other car owners before. Therefore, you should visit specialized forums or simply chat with other motorists. In this case, you may find several answers to your question. After warming up, the carburetor completely closes the air damper, leaving the throttle valve operational. If the idle speed is not set correctly, the engine will only run on intake. But this is the main reason, there are many popular troubleshooting methods:

• rapid engine overheating and serious problems with the cooling system of your power unit;
• the valves are very poorly adjusted - no adjustment was made for several years in a row;
• the carburetor is not calibrated, the mixture is too lean, the system introduces too much air into the combustion chamber;
• The mixture can also be too rich, causing fuel overflow and problems in some carburetors;
• the carburetor jets are clogged, fuel does not pass through them well, which causes problems with the quality of the mixture;
• gasoline is incredibly bad, filters are clogged, the flow rate of the fuel system has become much lower;
• Problems have arisen inside the carburetor, membranes and gaskets have broken, fuel is leaking.

The latter case is especially popular on domestic cars. Due to improper operation of the fuel pump and other problems that could become a problem in the operation of the power unit, the carburetor simply stops working normally, its main functions are disrupted due to damage to internal parts. This is also one of the more difficult types of breakdowns, so you will need to spend a lot of time or money to fix this problem. Therefore, it is worth first checking and eliminating other possible problems that may be causing such problems. In particular, you can check all the above points, which can also cause the carburetor to malfunction and stop heating.

We carry out diagnostics and repair work on the carburetor ourselves

You can take advantage of the carburetor's superior capabilities if you know its design and have performed simple repair work in the past. Otherwise, we do not recommend that you try automatic recovery. These repairs will end up costing much more than what a technician would have cost. If you have experience and confidence in your abilities, you can use the advice of experts to carry out quality repairs on your car. Among the main work to be carried out, the following processes can be identified:

• remove the carburetor cover with the air filter and try to start the car while it is warming up, lower the air intake and do not look at the position of the shock absorbers, perhaps adjusting them will be enough to restore the car's operation;
• if this does not help, check the operation of the fuel system; perhaps the fuel pump stops pumping fuel after a certain period of normal operation;
• also inspect the cooling system, no matter what the indicators on the instrument panel say, look at the antifreeze level, make sure that the thermostat is working;
• You can also replace the air and fuel filters so that fuel and air flow into the carburetor smoothly and in sufficient quantities;
• The last stage of work is removing and disassembling the carburetor to install a repair kit, new gaskets, membranes and other parts, as well as cleaning this device from contaminants.

You can spend a lot of time wondering what the problem really is, or you can just go to an auto parts store, buy a carburetor repair kit installed under the hood of your car, do the necessary work and get the cleanest job possible. This is the only way to achieve high-quality operation of the equipment and the absence of problems with the power unit. After diagnostics and corrective work, the carburetor will definitely stop tormenting you with constant stoppages of operation. This will allow you to use your vehicle efficiently and safely.

Carburetor repair by specialists is the best solution

If you have a carbureted car, it is best to find a professional who can regularly assist the technician. Your car will regularly require high-quality maintenance, since the carburetor is constantly clogged, which causes more and more new problems during operation. Therefore, it is better to use the services of a specialist who knows his business very well and performs cleaning, regular maintenance and repair of carburetors, as well as all related equipment. The main criteria for choosing a specialist are as follows:

• experience working with your car model, sufficient professionalism, confirmed by years of work;
• positive reviews from other owners of carburetor cars who received quality service;
• affordable prices - no need to choose an expensive gas station, you can work with a private technician;
• fairly quick completion of all necessary repair work, but there is a guarantee of the quality of the result;
• the ability to order complex work with the purchase of spare parts from a specialist in order to relieve oneself of responsibility for the quality of spare parts;
• other convenient services, in addition to the possibility of a full car service.

it is convenient when all repair and maintenance issues are carried out by one person. This makes it easy to get a quality car because the person or company is responsible for it. If the carburetor is repaired by one person, the car is repaired by another, and problems with the generator are solved by a third party, all this is not very convenient for repair work on the car. So it’s better to find a universal technician and constantly repair your car exclusively from him. If your car has a Solex carburetor, we suggest you watch a video about its disassembly and maintenance:

Let's sum it up

Beautiful cars with carburetor engines have gone down in the history of the industry, but are still widely represented on the roads. That is why you can use the ideas presented in this publication, since there are still many carburetor masters, and the necessary spare parts can be found in stores. If your car has problems with the quality of its fuel system, it's time to fix all these problems. You can simply get high-quality transmission and fuel system performance if you take care of all the important components of the car.

For normal operation of the carburetor, it is enough to clean it from time to time. This point is very important for any car operated in Russia. Fuel quality, air pollution - all this affects the normal operation of the engine. It is enough to thoroughly clean the fuel system once every few years, performing certain maintenance procedures to ensure long-term and high-quality operation of all engine systems. How did you repair a carburetor car?

The problems with the car are different, but for some reason the Gazelle 405 injector does not start so often. Drivers begin to get confused, but sometimes a solution to the problem is still impossible to find.

Now let's look at some of the most likely malfunctions in which the car will not start.

When this happens, you should first inspect all the wires, spark plugs, rail pressure and injectors. Most often, the Gazelle 405 injector does not start due to the spark plugs, so it is enough to replace them. But sometimes the problems are more serious than candles.

Why does the Kamens engine not start?

In order to start the Cummins diesel engine installed on a GAZelle car, the initial rotation speed of its crankshaft must be 150...200 rpm.

Let's look at the main reasons why an engine may fail to start.

When compression drops, the air in the cylinders is not compressed to the required level, and therefore does not heat up to a temperature sufficient for self-ignition of the sprayed diesel fuel.

A fundamentally opposite malfunction, in which, as in the first case, a GAZelle with a Cummins engine does not start, is clogging of the electromagnetic injectors, as a result of which fuel simply cannot enter the hot air environment due to existing mechanical barriers.

A low battery charge level does not allow the starter rotor to accelerate to those cherished 150-200 rpm, as a result of which some of the air, when compressed, manages to run through the smallest cracks and gaps into the under-piston space. As a result, as in the case of compression failure, the temperature in the cylinders does not reach the required value, and fuel ignition does not occur.

But there are also cases when the battery is completely charged, but the starter is still not able to develop the required rotation speed. Problems with the starter come from various origins and often require its dismantling and careful inspection.

This can happen even if the car has been parked for a long time, it’s a fact

pull it in tow, the hydraulic compensators have lost oil and the clearance on the valves is completely different, or even there is no compression at all, pull it in 2nd-3rd gear for 700-1000 meters, the compensators will pick up oil and everything will fall into place, compression will appear in time

very good advice! There are no words for it!

One day the Gazelle stopped starting? The reason lies in engine malfunctions. The problem may be related to both the mechanical part and the electrical part. To fix the problem, you will have to diagnose a number of parts.

Cummins diesel does not start - what to do

Cummins diesel won't start? Does even such a reliable engine also have breakdowns? Although this engine has gained the status of an unpretentious, durable and reliable power unit, unfortunately, like all diesel engines, it can break down. So what to do in such a situation? There are only two ways of development.

If you have already repaired a diesel engine and know almost everything about it, then your path is to fix the problem yourself. Those who have no experience in repairing and servicing a Cummins diesel engine may choose another path.

In this case, you will have to tow the car to a service center, where they can fix all the problems.

If you decide to tackle the broken engine, then it’s worth noting right away that you shouldn’t start a Cummins diesel from a tow. It is also not recommended to “light it”. If you do this, then the likelihood that the engine will not only not start, but will also break down is very high.

We must not forget that cars with a Cummins engine have an electronic control unit, which in turn controls all systems of the power unit. If you try to start the engine from someone else's battery, then during such a start voltage surges may occur, which can damage any sensors or the electronic control unit.

As a matter of fact, for the same reason it is not recommended to start a diesel engine from a tugboat.

Cummins diesel diagnostics

When any equipment fails, we diagnose it. Also here. When a Cummins diesel engine does not start, it is necessary to carry out diagnostics, but this does not mean that you need to connect a computer to the electronic unit. Not at all! First you need to find out what condition the battery is in.

If the starter does not turn the engine or turns it too slowly, then most likely the cause of your problem is the battery. In this case, try first charging the existing battery or replacing it with a new one.

Let's now look at some more malfunctions that can occur if the lights on the dashboard come on when you turn the ignition key, but the starter doesn't even click.

There are possible problems here such as:

• Lost contact on the starter
• Starter relay burned out
• The ignition switch is faulty
• The solenoid relay is faulty

It is best to call a specialist if you have never dealt with car wiring.

He will be able to quickly and efficiently eliminate all faults.

The main thing to remember is that an inexperienced hand in the electrical wiring of modern cars can cause big problems with the equipment itself, and all this can also cost a tidy sum, for example, due to incorrect connection of contacts.

Based on this, we can conclude that you should not skimp on an experienced specialist, since his experience will not only help you do everything efficiently, but will also allow you to save a large amount of money, since you will not have to restore the car after unqualified intervention in its systems .

and if you no longer remember when you changed the filter, or simply did not track changes in the mileage of the car, then you just need to check the condition of the replacement filter cartridge

It is also worth paying attention to the presence of water in the filter housing

If you find that there is quite a lot of water, then this could be the real reason why the diesel engine is unable to start. To eliminate this malfunction, it is imperative to replace the fuel filter and bleed the system so that all excess water comes out.

The car doesn’t start well when it’s hot: we look for and fix the problem

Modern cars are gradually moving from the concept of a mechanism to the concept of an organism. This is a very complex system that requires ideal operating conditions. The high power of the engine, which survives everything that can be squeezed out of technology, and other features of modern automobile manufacturing indicate that modern cars need special attention to ensure they last for a long time. One of the most common problems with improper car care is poor engine starting after warming up. This means that if you park in front of a store for a few minutes, you will not be able to start the engine properly. The problem lies in two possible failures, but there are also extreme cases. Today we will deal with the most common problems in this case, and also talk about private variants of the problems.

It should be noted that the symptoms of a bad hot start can manifest in different ways. The car usually refuses to start until the engine has cooled down to some extent. Another power unit starts only on the third or fourth attempt, and the third one just needs to be turned for a long time to start. In any case, whatever happens to your machine in this context, you need to find the problem and make sure that you fix it. This task is a precursor to more serious failures that will cost you much more money to fix. So, let's figure out why the car has trouble starting in hot weather.

Bad fuel or presence of additives in the fuel mixture

Low-quality gasoline or diesel fuel is one of the most common variants of this problem. But in this case, you can conduct an experiment that will show the real problem of your car. The fact is that low-quality fuel with poor starting on a warm one will be even more unpleasant when starting a cold engine. Therefore, it is enough to cool the car, wait for the engine to normalize and start it. Additionally, there may be the following problems with fuel:

• gasoline or diesel fuel may contain an additive that your engine will not accept;
• the diesel fuel has frozen and acquired a gelatinous form, which is difficult to pump;
• there are solid particles in gasoline, the filters are clogged and it is difficult for the pump to pump the required amount of fuel;
• The settings of the engine control system and air supply have failed, perhaps one of the valves has broken;
• The idle air valve as well as the mass air flow meter (mass flow meter) can cause such problems;
• There is only one functional feature of carburetor engines: a very hot unit does not start well.

In the case of carburetor units, everything is quite simple - the engine itself starts very poorly in hot weather. This is due to the fact that after stopping a car with a hot engine, the temperature in the carburetor area is quite high. Gasoline quickly evaporates under the influence of temperature and fills all chambers and pipes of the carburetor in a gaseous state. But the tray remains empty. If you decide to start the engine within five minutes of stopping, you will encounter difficulty starting because there is no liquid fuel in the chambers. Problems can be solved by manual pumping or several attempts to start the power unit. However, there cannot be such problems with injectors, since the fuel is supplied directly from the line. Therefore, it is worth looking for other problems in the fuel system.

Too rich or lean mixture - air flow sensor

We said above that problems with starting a car can arise due to a failure of the mass air flow sensor, mass air flow sensor. This element of the car is one of the most sensitive to environmental influences, so we often talk about its breakdown. If it is very difficult to start the engine when hot, check the operation of this mechanism. In addition, this breakdown may be accompanied by the following factors:

• breakdowns when pressing the accelerator pedal, lack of traction at certain moments;
• a decrease in power or vice versa - an inexplicable increase in the potential of the unit;
• complication of engine starting and periodic filling moments;
• explosions inside the exhaust system when the accelerator pedal is sharply pressed;
• unstable speed due to periodic changes in mixture enrichment.

The mixture of gasoline and air must have a certain consistency, which is formed by the mass air flow sensors and several other parts of your car's electrical and electronic system. If these parts are faulty, you will have to replace them and test the machine and adjust the operation of the new equipment.

The fuel pump has overheated - a common problem in domestic cars.

The fuel pump is cooled naturally by pumping cold fluid from the fuel tank. But in extreme heat, this fluid cannot be cooled in any way, so the fuel pump will overheat. This is an unpleasant accident that may make it impossible to start the car when it is hot. The car could simply get stuck on the road and not start either from the pushrod or from the starter when turning the ignition key. There are several ways to solve this problem:

• take a cold damp cloth, attach it to the fuel pump and periodically wet it with cold water, cooling it;
• open the hood and place the car in the shade, let all parts of the engine unit cool normally;
• change the fuel pump if it is possible to quickly get another part of the fuel system;
• just wait for the fuel pump temperature to normalize and continue driving the car;
• An overheated fuel pump is unlikely to work properly, so it is better to replace it.

This problem can cause the failure of important parts of the fuel pump, because when it overheats, it simply does not stop working. If nothing changes after the car cools down, the fuel pump will need to be replaced. But usually a cold car starts and then continues to drive without problems for several days.

Problems with poor starting of gas cars in warm weather

Many drivers, after reading all the above arguments, will say that they are not relevant for their car, since there is a gas installation. Several years ago, it became profitable to drive on gas, so many car enthusiasts found LPG under the hood. If your car stalls and won't start in hot weather, you need to let it cool completely, then start the car and drive straight to the gas station. It is better not to get involved with this issue for various reasons:

• due to high temperatures, some seals may fail and gas pipes may open;
• possible loss of the working environment of the fuel system of your car for other reasons;
• expansion of gas in a cylinder at high temperature creates a certain pressure in the system;
• It is better not to refuel with gasoline during hot periods, limiting yourself to partial refueling;
• It makes sense to contact a specialist if such a problem begins to occur on your machine.

It’s hardly worth messing with gasoline cars—even the latest generation of gas equipment poses a certain danger. If your car does not start on gas, it is worth hiring a specialist to solve this problem. This way you can easily obtain the necessary performance characteristics of the power unit, and also do not expose yourself to the danger of improper operation of the fuel system. We invite you to read the experts’ explanations about an unsuccessful start in the hot season:

Let's sum it up

High-quality fuel systems rarely fail, so even in the hottest climates, hot cars start moving. But if such a problem occurs, the driver is unlikely to be able to solve it on his own. There are too many possible failure factors that are difficult to manage without special knowledge and certain tools. Therefore, it is better to show the car to specialists and get a very specific answer to your problem. Most likely, repairing this problem will involve minor sensor replacements and not too expensive procedures.

Therefore, in most cases, turning to the experts will be the key to a successful car trip in any weather. It is necessary to contact a service station as soon as symptoms of poor car starting begin to appear in your case. The sooner you come to the master, the easier it will be for him to help you. And the cost of repairs increases when you postpone a visit to the specialist. Have you ever had a similar situation while driving a car?

There is a spark; gasoline is supplied to the gazelle; the engine injector does not start.

If there is leakage from the throttle body, then it is not oil, but antifreeze. You fill the spark plugs, it won’t start at all. Tried starting it with a gas engine. bayan:

Added after 2 minutes 27 seconds Gasoline has been filled since September, and as I understand it, the car sat motionless all winter.

The gas pedal does not respond to the engine at all. I got two charged spare spark plugs from my battery. So it can't be because of gasoline? I'll try with a push.

Added after 2 minutes 20 seconds Yes, the car sat all winter, at the beginning of winter I started it a couple of times, and even then with difficulty. After this it won't start at all.

Not only that, the coolant temperature sensor plays an important role, the price of the part is 120 rubles, in addition, the specified sensor is not tested if MIKAS 5.4 is installed. buy it, connect it without installing it in the thermostat, if it’s the one that will start the car.

The possibility of valves sticking cannot be ruled out.

You can simply remove the connector from the DT. In this case, the ECU will see a temperature of 0 degrees. I would also try removing the MAF connector.

If tasol gets into the injector, how can antifreeze get into the injector? Or rather, what do you mean by “injector”?

then during startup there will be a vacuum in the intake and all this will fly into the combustion chamber, and during startup and during operation there should be a vacuum in the intake. Without it, the engine will not start. This is one of the cornerstone conditions for the operation of an internal combustion engine. In general, these two phrases are absolutely incomprehensible to me personally.

Tasol enters the injector from the heated valve as described above.

It is clear that there is a vacuum in any case, both during starting and during operation. I just wrote it this way to make it clear.
