After replacing the timing belt, the car does not start: causes and solution to the problem

Replacing the drive elements of the gas distribution mechanism is a planned procedure that is performed at certain intervals or as necessary.

In the first case, we are talking about replacing the timing belt or chain, as well as rollers, chain tensioner and other drive parts after a strictly defined number of kilometers traveled (on average for a belt the figure is 50-60 thousand, for a chain – 150 thousand or more) . Also, the reason for an unscheduled replacement of a belt or chain may be accelerated wear, the appearance of extraneous sounds during operation, etc.

We also recommend reading the article on how to change the timing chain yourself. From this article you will learn about the procedure and features of the procedure for replacing this element.

In some cases, a situation arises when, after replacing the timing belt or chain, the car engine does not start. This problem can occur on cars regardless of the make and model of the vehicle, the design features of the power unit, etc.

In this article, we intend to talk about why the engine does not start after replacing the timing belt, and also why, after replacing the timing belt, the power unit starts poorly, the internal combustion engine is unstable, or other problems arise with the engine.

People, help, it won’t start after replacing the timing belt!

Good evening everyone!
I decided to change the timing belt, when disassembling I saw that the front oil seal was leaking = changed it, then I decided to go through and wash and clean the VCG system, I was disarmed that the ejection pump was not working = installed a new one, the valve on the DZ pipe (with a stone, blows in all directions) didn’t bother, left it as it was Yes, one pipe was replaced with a simple oil-resistant one. I took it apart and removed the manifold and immediately replaced the gasket under the intake manifold. The TDC marks coincide, the engine is turning, there is a spark, the injectors are spitting gasoline, the compression is 11 in all. The car is assembled but without headlights, radiator grille, bumper because... I want to go to the car wash to wash the air conditioner radiator.

Is there anyone from Berezniki (Perm region) who could come and do a diagnosis. Let's agree.

PS Maybe she should get headlights so she can start

, Did you mix up the wires for 1.2 spark plugs?

Phases of the GRS mechanism

The phases of the gas distribution system are precisely what makes the car engine function simultaneously, without disruption. If these very phases go astray, then either the piston will not reach TDC at the right time, or the valve will lag behind, in a word, problems are inevitable.

The phases of the gas distribution system are always set according to the markings, due to which clear and synchronous operation of the motor is achieved.

Phases of the GRS mechanism

If you need to set the timing marks correctly, you will have to remove the belt. You will have to stock up on keys, screwdrivers and all those tools that will make the work easier. For example, a wrench for socket heads - this is convenient for attaching a nut almost anywhere.

Every expert will confirm that the GDS phases must be installed from the factory. But during active operation of the engine, repairs, etc., the phases shift, the car begins to pull poorly and the motor vibrates.

Algorithm for carrying out an operation to diagnose the correctness of marks:

The top belt protection cover is removed.
The gearbox switches to 4th.
The car is pushed forward until the marks on the shaft coincide with the markings on the cover (bottom).
Now you need to look under the hood.
Here, find the clutch housing, remove the rubber lock from it, which blocks access to the hole through which the mark on the flywheel is clearly visible.

After replacing the timing chain or belt, the engine does not start: main causes and troubleshooting

Before diagnosing the timing drive, it is recommended to immediately check the proper operation of the ignition system, the condition of the battery, the correct connection of parts of the power system, electrical sensors of the ECM, etc. If no defects are identified, then we move on to the gas distribution mechanism drive.

Similar malfunctions can occur on various car models. First, it is important to know that mistakes when replacing the timing drive can lead not only to failures, but also to further breakdowns. It is also necessary to separately take into account the reason why the drive elements had to be changed.

After replacing the timing belt, the car does not start

After changing the timing belt, the car

does not start? Several reasons why

It sometimes happens that after replacing the timing belt, the car does not start. The problem can occur on different cars. This may appear on different models. The prerequisites will always be approximately the same. It is better to eliminate them immediately after identification. For this purpose, it is worth knowing what remains to be done for our client regarding defects that prevent the engine from starting. By and large, there are not that many of them at all. It is also important to change the timing drive (gas distribution mechanism).

No matter what mistake leads to the following dilemmas. Before checking the timing drive, be sure to check the condition of the ignition accounting program complex and the battery. Cause you'll like it better here.

Car won't start after timing belt replacement

.
If this problem occurs after the belt
, then the cause must be sought in this. If the drive breaks, the valve timing is lost. Most often, a collision between pistons and valves occurs. This ends, at best, with bending of the valves, and at worst, with damage to the pistons.

Many manufacturers at one time made pistons with this danger in mind. They have special recesses for valves on the upper surface of the pistons. Such engines can be seen on VAZ - 2108, 2109. Also, some cars of the tenth family were equipped with similar engines. Among foreign cars, such pistons can be found on some Mitsubishi, Renault and some other brands. But only on fairly old cars.

After replacing the timing belt, the car does not start.

It turned out that such grooves significantly reduce engine power.

There are two ways to identify a problem with the valves:

Remove the valve cover and carefully crank the engine. At the same time, carefully monitor the operation of the valves. If one does not work, then most likely it is bent. This method is not reliable; in many cases the valves will work as they should;
A more reliable way is to study the condition of the valves directly on the removed head. All bent valves are visible to the naked eye.

Topic: Resolved: Stopped starting after replacing timing belt

Actually the background. For the time being I drove normally, sometimes at speeds of 160 km/h and in traffic jams, no complaints. But one night, it stalled while I was standing at a traffic light in neutral. repeated attempts to start it to no avail. drove it away and removed the timing case. Here I discovered that the belt itself was intact, but one gap of 10-15 cm was completely without teeth. well, it doesn’t happen to anyone, it was decided to replace the bearing and pump along with the timing belt. disassembled, marked, put back together and EVERYTHING. it won't start and that's it. The fuel pump pumps, the engine sneezes, but does not start. We decided to have a light. no sense. We decided (!) to pull in 2nd gear, the check light is on, there are revolutions, but again no result. We smoked, scratched, spat and went home. Help me with advice on what to do? car 21101 engine 1.6 8kl

Re: Solved: stopped starting after replacing the timing belt

In theory, the valve couldn’t have been bent by 8kL, so I don’t think it’s anything serious. It’s also worth looking at the crankshaft position sensor and the pulley adjacent to it, is it tightened? Are the tags set correctly?

Re: Solved: stopped starting after replacing the timing belt

Yes, check the pulley; sometimes it sits crooked and then it will cause a lot of problems. One friend already had this done and his whole head was broken, why wouldn’t it start?

Re: Solved: stopped starting after replacing the timing belt

In short, it was not the reel))) For the future, for me and for everyone who doesn’t know. On the flywheel, in addition to the risk that needs to be set, there are some kind of holes. My flywheel is not exactly dirty, but like a CPU in the barracks it is not clean. So, instead of the risk, I put the edge of this hole, since it is somewhat similar to this risk. More info for the future: 1. the camshaft (the one on top) makes ONE revolution, the crankshaft (like the flywheel) makes TWO revolutions. That is, after you have set the marks and marks and pulled the cigarette out of your mouth, but the car does not want to start, turn the flywheel one more revolution. 2. I tightened the timing belt as follows: I set the marks of the camshaft and flywheel JUST below the level. When you tighten the belt and if you decide to drink alone, it will help. Why, you will understand for yourself. 3. After your hellish tarantas has deigned to start and you have driven the first kilometers, do not be alarmed by the new noises of the car. At least the sound from under the hood has changed a little (most often I drive without music, so I know where everything is and how it makes noise in my car)

Operation of the gas distribution mechanism

The principle of operation on all engines, when it comes to types such as internal combustion engines, is almost the same. All work can be divided into 4 stages:

fuel injection;
compression;
duty cycle;
removal of exhaust gases.

Fuel is supplied to the combustion chamber by moving the crankshaft from top dead center (TDC) to bottom dead center (BDC). When the piston begins to move, the intake valves open and the fuel-air mixture is supplied to the combustion chamber. After this, the valve closes, during which time the crankshaft rotates 180 degrees from its original position.

After the piston reaches BDC, it rises up. Consequently, the compression phase begins. When TDC is reached, the phase is considered completed. At this time, the crankshaft rotates 360 degrees from its initial position.

We set the timing belt ourselves

The process of setting tags yourself is not that complicated, but it does require some in-depth knowledge. Among other things, it is periodically necessary to check the position of the shafts, since they tend to change their location relative to other timing elements for various reasons. In the following two situations, you have to set marks almost every time:

During a complete timing belt replacement: the shafts will need to be set in the correct position, otherwise engine operation will be impossible
During repair of the gas distribution mechanism, adjustment of their position is also required

It should also be taken into account that on cars with a sports camshaft, the principle of setting the drive belt may be completely different. To know exactly how to do all the work on sports or tuned cars, it is best to familiarize yourself with the detailed information provided in the instructions for a specific power unit.

Having all the necessary tools in hand, you can proceed directly to the main work. All work comes down to the following steps:

Removing the battery
Jack up the right front wheel
Then we find the camshaft and crankshaft
Then you need to find a risk on the shaft pulley
Find the mark on the engine block
Align the two marks by turning the wheel
Rotate the wheel until the two marks completely coincide

Then, in reverse order, we collect everything that was originally removed. This method is suitable if the timing belt is fully tensioned. If the marks do not match, you will have to remove the belt and place marks separately on the crankshaft and camshaft.

Signs of wear

Several symptoms will indicate a worn chain. To avoid having to overhaul the engine (which is usually very expensive), it is necessary to change the chain as it stretches.

If the engine idles roughly and unevenly, then the chain is already “fit.” This type of engine operation is due to the fact that the valve timing has changed. If the chain chirps at idle, then this is also one of the signs that irreparable malfunctions of the timing drive may soon occur.

If, after removing the cover, it is clear that the tensioner has reached its maximum distance, if wear appears on the teeth of the sprockets, then it is best to replace the chain.

After replacing the timing chain or belt, the engine does not start: main causes and troubleshooting

Before starting diagnostics of the timing drive, it is recommended to immediately check the proper operation of the ignition system, the condition of the battery, the correct connection of power system elements, electronic ECM sensors, etc. If no malfunctions are identified, then we move on to the gas distribution mechanism drive.

In the list of the main reasons why the car does not start after replacing the timing belt or problems appeared after the chain drive was changed, experts identify possible damage to the valve mechanism and misaligned valve timing as a result of improper installation.

Similar faults can occur on different car models.

First of all, it is important to know that errors when replacing the timing drive can lead not only to failures, but also to subsequent breakdowns. You also need to separately take into account the reason why you had to change the drive elements

The engine does not start: the valve is bent

For example, if the timing belt breaks, then the belt is changed and the car does not start, then bending of the valves after such a break should not be ruled out. The fact is that at the moment the belt breaks, the valve timing on many engines is disrupted, the camshaft does not rotate, and the timing belt stops working. This means that the valves no longer open and close in a timely manner.

However, the pistons in the cylinders still continue to move. It often happens that the valves remain open, causing the pistons to hit them. In this case, the valves become bent, and the pistons can also be damaged. At the same time, replacing the timing belt alone cannot solve this problem, since the engine requires separate expensive repairs.

Note that previously, internal combustion engine manufacturers took into account the risk of bending and machined special recesses for the valves on the piston surface. At the same time, the presence of such grooves reduces engine power, as a result of which such a solution was abandoned on modern engines.

The valves can be checked in the field by removing the valve covers, after which the engine is cranked by hand and the operation of the mechanism is assessed. If it is noticed that any valve is not working, then it is bent. Please note that such a check is just a superficial diagnosis, since even with bent valves the mechanism will often visually work normally.

For this reason, to accurately assess the condition of the valves, it is preferable to remove the cylinder head. Once removed, bent valves can be quickly identified and the procedure for replacing them can begin immediately.

Please note that it is recommended to replace all valves immediately with new ones, and not replace only bent ones. Also, during the installation process, it is necessary to grind in the valves.

Timing belt replacement performed incorrectly

Unqualified replacement of the timing drive often leads to the fact that after replacing the timing chain, the engine does not start well, a belt-driven motor does not start, etc. The problem is that the timing belt may not be aligned and the phases may not match.

The result is that the operation of the gas distribution mechanism and the ignition system is not synchronized, the mixture is compressed in one cylinder, and a spark is formed in the other.

For these reasons, an important point is the exact match of the marks on the pulleys

During the replacement process, special attention should be paid to the position of the marks. The engine is set to the end position of the compression stroke in the first cylinder, after which the position of the marks is checked

If a deviation is noticed, then this is the reason the engine refuses to start. In such a situation, the timing belt must be removed and the camshaft pulley must be correctly aligned taking into account the marks. Let us add that many car models also have a special mark on the flywheel, which must also match.

It should be noted that the flywheel is usually dirty. In many cases, this makes the tag difficult to detect. As practice shows, on the flywheel, in addition to the mark that needs to be set, there may also be characteristic indentations-pits. If you mistakenly replace the mark with the edge of the hole, which is visually similar to the mark, then the engine will not start.

Also, during the process of replacing the timing drive on cars with a carburetor, the ignition may go wrong. Quite often, a violation of the spark supply to the cylinders can be determined by installing the spark plug armor wire of the first cylinder to the fourth, and the wires from the fourth cylinder to the first. In some cases, after such a rearrangement, the engine can be started.

If such a failure is detected, then the gas distribution mechanism drive must be set correctly, and if necessary, additional adjustments and adjustments to the ignition system are also made.

Problems in the cliff

After replacing the timing belt, the car does not start. If this problem occurs after the timing belt breaks, then the cause must be sought in this. If the drive breaks, the valve timing is lost. Most often, a collision between pistons and valves occurs. This ends, at best, with bending of the valves, and at worst, with damage to the pistons.

It turned out that such grooves significantly reduce engine power.

There are two ways to identify a problem with the valves:

Remove the valve cover and carefully crank the engine. At the same time, carefully monitor the operation of the valves. If one does not work, then most likely it is bent. This method is not reliable; in many cases the valves will work as they should;
A more reliable way is to study the condition of the valves directly on the removed head. All bent valves are visible to the naked eye.

An article on the topic “Which VAZ engines do not bend the valves.”

If you determine that the valves are damaged, you will have to replace them. This must be done as a complete set. Don't forget to grind the new parts properly.

Tips and tricks

On cars with a timing belt, it is strictly not recommended to limit yourself to just replacing the first belt. At the same time, new rollers should be installed. Ignoring this rule may lead to another jamming of the rollers and breakage of the new timing belt.

Also, after installation on old rollers, the new belt may slip and wear out faster. Even if the engine starts normally, you may encounter noticeably increased noise during engine operation.

Let us also add that, structurally, the timing belt can also drive the pump (water pump of the cooling system). During replacement, you should separately check the condition of this element, and also change the pump strictly according to the regulations. If the water pump jams, then the belt may also break.

This suggests that during the work the contact chip for some sensor could have been damaged. To accurately determine the cause, the engine can be scanned for errors using a special OBD2 scanner.

When selecting belts and rollers, it is necessary to install high-quality analogues or original parts. You can purchase spare parts either as a ready-made installation kit or separately. Remember, low-grade counterfeits of ready-made timing belt installation kits from well-known companies Gates, Inna, etc. may be found on sale.

Finally, we note that replacing the timing mechanism drive is rightly considered a responsible procedure. Incorrect installation can lead to engine failure or unstable operation of the power unit. If you are not confident in your abilities, then it is better to entrust this procedure to experienced car service specialists.

Lighting up correctly

"Lighting". another way to start the car.

First of all, keep in mind that the wires for lighting should have the largest possible cross-section. The cars are placed with their hoods facing each other, but not touching each other. The positive terminals of both car batteries are connected by one wire. The other wire is connected to the negative of someone else's battery, and the other end is shorted to ground.

Do not lay wires to the negative of a discharged battery. This way you can only charge the battery, but not start the engine, although in some cases this is enough.

If the engine does not start, move the crocodile directly from the negative battery of another car to the negative terminal of the discharged battery. Be careful, touching the positive terminal will cause a short circuit.

After starting, do not rush to remove the wires, let the engine run for a while. Remember, the negative wire is removed first; the headlights cannot be turned on so that they do not burn out during a power surge.

Possible reasons

First, you need to understand what you've recently done to the engine. This is the only way to determine the possible cause of the malfunction. For example, if the car does not immediately pull after replacing the timing belt, then, of course, you should check the condition of the element. There can be many reasons why the car does not pull and the engine power drops. Let's look at the most common of them:

First, you need to check the installation of the timing belt (the marks may be set incorrectly, which is why the car does not pull).
Diagnose the functioning of the injection nozzles - sometimes the problem lies precisely in clogged injectors. If your vehicle is equipped with a carburetor engine, then you need to check its settings. The carburetor may be clogged and will need to be cleaned.
Check the ignition (if it is too late or too early, then there may be a problem with the engine power).

In addition, other problems may be causing the loss of power. For example, a clogged fuel filter. But we will look at solutions to common problems.

Checking the batteries

If the scooter does not start in both cold and warm weather, the owner should check: the gas tank, enrichment, tap, filter, carburetor and pump.

First, it is recommended to diagnose the fuel tap. To do this, you need to disconnect the hose from the carburetor and turn the crankshaft. If everything is in order, gasoline will begin to flow out of the tube. But if the fuel does not drain or flows even when the engine is not running, then the valve should be replaced.

The second stage of diagnosing the power system is inspecting the fuel filter. If a component becomes clogged, it should be replaced. But even if the filter is clean, but it is not blown out, it means that a blockage has formed in it.

Due to contamination of the carburetor, problems with starting the engine may also occur. The cause of the blockage is low-quality gasoline or an ineffective filter. To solve the problem you need to:

Remove and disassemble the carburetor.
Blow out and clean all openings. For cleaning, use a compressed air cylinder or a simple compressor.
Check the float chamber and its components.
Clean the fuel jet.

It is also worth remembering about the most banal problems - lack of fuel or old gasoline. If after a long period of inactivity the scooter does not start from the button, you should drain the old gasoline and fill the tank with fresh fuel.

Sensor check

There are several ways to diagnose a controller. The most accurate option that will allow you to obtain an oscillogram is to use special equipment. An oscilloscope will not only determine the state of the controller, but will also make it clear that the device will soon fail. Not every electrician has such equipment, so simpler, but no less effective options are discussed below.

Diagnostics with a multimeter

Before testing, the device must be set to DC measurement mode, the operating range should be 20 volts. You will also need two metal pins. Before carrying out diagnostics, the rubber cover is removed from the device connector.

The preliminary check procedure to determine that the necessary signals are supplied to the Hall controller is performed as follows:

The main armored wire is disconnected from the distribution unit. It must be connected to the vehicle ground to prevent accidental discharge. Because this will cause the power unit to start during diagnosis.
Then the ignition system is activated.
The connector is disconnected from the distribution mechanism.
The tester is set to DC mode with a range of 20 volts.
The negative contact of the multimeter is connected to the car body, you can choose any place. The positive output of the tester will be used to measure the operating voltage parameter.
The connector connected to the distribution unit is equipped with three contacts - red, green and white, but the colors of the conductors may be different. At the first output the voltage value should be 11.37 volts or about 12 V, at the second output it should also be around this value. And on the last conductor the operating parameter should be 0 volts.

Starting a car in winter

Winter launch. a separate topic. To start, you just need to turn on the ignition. In this case, the low beam will turn on automatically; you need to keep it on for at least 20 seconds, and then turn it off to accumulate the starting charge. Do not turn on other devices.

Move to neutral and press the clutch. Turn the key and listen to the starter. After a few revolutions the engine should start. If this does not happen, it means that the starting charge has not reached the target, and it needs to be accumulated again. If the second attempt fails, the battery is frozen. There are only two options: start with another car (the so-called lighting) or take home the battery for heating. As a last resort, there are still attempts to start in tow, including second gear. This method does not work on a Grant with automatic transmission.

Serious damage

And here it’s worth starting with a broken timing belt. The motor spins, but very easily, since the valves are all open. Check the belt right away to see if it is in place. Moreover, sometimes it happens that the front part is intact, but the back part, which runs along the roller and pump, is torn. Remove protection and check integrity. Of course, you can’t do without replacing the belt, so there should always be one in stock, at least a little “alive”.

If the engine does not start, but the starter spins quickly without engaging the flywheel crown, then we can conclude that the teeth have worn out. Try turning on third gear and pushing the car forward 30 centimeters. The crankshaft will turn a little and there will be a whole section of the crown opposite the starter. If the wear is too great, you will have to start it only from a tug.

Breakdown of the starter and oxidation of the negative wires can also cause the engine to not start. In the case of the starter, there are two most common breakdowns - the bendix, or more precisely, the overrunning clutch, and the brushes. It is very easy to check the overrunning clutch; you just need to turn the gear in both directions. In one it should rotate freely, but in the other it should not rotate.

Often, drivers are faced with the fact that their VAZ 2109 stops starting

for some reason. If the car does not start, the question immediately arises, “Where to start?” In fact, everything can be quite simple, and in 90% of cases this is a typical problem that is quite easy to diagnose and solve.

Why did the engine stop?

Possible reason for the engine stopping on the road. throttle valve clogged. The problem is solved by cleaning it. Contamination of the fuel filter with low-quality fuel can also cause the engine to stall. Sometimes this only appears long after refueling. There is only one way out: drain the bad gasoline and replace the filter.

Has the engine stopped running and won't start? Most likely, the generator is broken or the drive belt is broken. In this case, the on-board network does not receive the necessary power, the battery is discharged and the starter can no longer rotate.

The Lada Granta may not start due to the fact that while parked one of the on-board devices, for example, the radio, remained on. Keep an eye on this when parking your car for a long time.

Circuit breakers

VAZ 2109 cars have a rather impractical location of the fuse box - between the windshield and the engine compartment. All dirt, dust and other deposits accumulate on this block.

If the lid is not sealed, moisture may get into the elements after rain, causing them to short out. The most basic one in our case is the fuel pump fuse. If it burns out, the fuel is unable to pass from the gas tank into the chamber. And no amount of “purging” will save you here. To avoid getting into such a ridiculous situation, experienced drivers are advised to always carry a set of new fuses with them.

If the Priora does not start well when hot

In this case see

In the second table, in addition to the reasons described, also note:. Let us remind you that in some cases the Priora does not start due to a faulty immobilizer or alarm system

In some cases, a flashing engine computer (electronic control unit) can help solve the problem of poor starting. And regular car maintenance will help eliminate problems with poor engine starting.

A pressure regulator capable of draining fuel through a diaphragm into the receiver. DPKV contacts, if the sensor has been changed, check that the poles are connected correctly. Faulty ignition module.

Let us remind you that in some cases the Priora does not start due to a faulty immobilizer or alarm system. In some cases, a flashing engine computer (electronic control unit) can help solve the problem of poor starting. And regular car maintenance will help eliminate problems with poor engine starting.

Dirty filter

Its blockage leads to the fact that the VAZ 2109 does not start

And it doesn’t matter whether it’s a carburetor engine or an injection engine. It's easy to check the condition of the air filter

On both carburetor and injection engines, you should remove the housing cover (the only difference is that on the first it is iron, and on the second it is plastic). Next, we take the element out and look at its condition. Paper filter elements should be light-colored. If they contain particles of dust and dirt, air cannot pass through them into the combustion chamber. Hence it turns out that the VAZ 2109 carburetor does not start: the starter turns, there is a spark. In winter, periodically inspect its external condition. A filter like the one in the photo on the right can no longer be used.

Yes, this will not harm the engine, however, there will be frequent interruptions in operation. As a result, the chamber will be filled with a too lean mixture - hence the lack of “traction”, power, failures in acceleration and high fuel consumption. By replacing this part with a new one, you will get rid of all these problems at once. By the way, the manufacturer recommends changing the air filter at least once every 10 thousand kilometers. If the car is driven in rural areas, where there are mainly dirt roads, this period should be divided into two. Dust and dirt are the main enemies of the filter.
