Chevrolet Niva won't start; the starter doesn't turn: it just clicks.

Often, owners of a VAZ 2121 or 2131 SUV encounter problems with starting the engine. For example, when you turn the ignition key, the starter does not turn. Let's look at possible problems with the Lada 4×4 starter and ways to solve them.

Where is the starter relay located?

Many drivers have encountered such an unpleasant situation when the starter does not want to turn the engine and start the car.
And it’s not a matter of the battery, because even no attempts are made to move the power unit. There is just a kind of click and nothing else happens. In such a situation, you have to push start the car or come up with other ways to start the engine. If the starter clicks but does not turn, there are several types of car problems that are worth paying attention to. This problem will have to be solved immediately after it occurs, because further movement is only possible with a working starter. Especially when it comes to large cars, which cannot be started from a pusher.

Every car owner will be familiar with this situation when the morning starts late and you start rushing to work or on errands. But it happens that after an overnight stay, the car simply refuses to start, or starts after numerous attempts.

And such problems are not the norm and require careful diagnosis and testing. Since there may be plenty of reasons for malfunctions, you should carefully read the main ones and check them in practice.

The starter is also tested under full braking. Often there may be a manufacturing defect.

If, when you turn the ignition key, clicks are heard from the starter relay, but the unit itself does not spin, then the problem may be associated with a malfunction of the control cable that powers the relay, or with a problem in the performance of the relay itself.

In such a situation, the car can be started if you short-circuit the “plus” from the battery to the positive control terminal from the ignition switch (the smallest wire of the three is connected to it). If, with such a connection, the starter starts to spin, then the malfunction is definitely not related to the battery, and the problem should be looked for in the relay, ignition switch or wiring.

In practice, most of the problems and malfunctions when the starter operates are problems with the electrical part. Mechanical failures are less common. Problems with starting the vehicle's power unit, which are caused by electrical faults.

If you cannot start the car, you need to check its battery for functionality, since the starter is powered from it. If the power supply is insufficiently charged, the characteristic sounds of the engine starting system may be completely absent. You can measure the battery charge using a voltmeter.

If it is less than 9V, it is necessary to recharge the battery, otherwise further loss of capacity may negatively affect its operation. If there is no tester, you can determine how charged the battery is by the brightness of the headlights, although this requires some experience. If, when the high beam is on and the ignition key is turned in the lock, the headlights begin to shine weaker, it means that the battery charge has decreased significantly.

If the starter clicks but cannot turn the engine, you need to test the solenoid relay. In addition to the failure of this part, problems may arise with the power cable. To determine the functionality of the relay, it is recommended to connect it directly to the battery terminals. If the traction works with such a connection, the cause of the problem must be sought in the power system (damage to the wires, burnt relay contacts, a malfunction in the ignition switch). After troubleshooting, the engine starting system will function properly.

Insufficient contact or its absence leads to a loss of current in the vehicle's electrical network, which is why its consumers function incorrectly. Therefore, it is necessary to periodically pay attention to all connections in the on-board network. For normal functioning of the starter, a current of approximately 200A is required. At a lower starting current, only the pull-in winding of the relay is activated. However, the power unit cannot start.

When the VR is not working well, when you try to start the engine, clear dry clicks are heard; if the cause of the defect is a contact relay, the clicking in this case is quiet and quite soft. First, we check the functionality of the starter itself, this is done something like this:

• remove the starting device from the car;
• We connect the terminal wires to the removed battery, connecting their other ends to the main positive and ground of the starter;

• we connect another wire to the starter winding, with its other end we touch the positive terminal of the battery, while holding the starting device;

• if the starter is working, the bendix will engage, the rotor will rotate, if not, there will be no rotation, and when voltage is applied, slight sparking will occur;

• To completely make sure that the starter does not respond or, on the contrary, responds to the power supply, we apply plus directly to the winding.

Now, without disassembling the starter assembly, you can check the operation of the solenoid relay:

• apply minus to the winding output;

• briefly touch the BP contact pin, where power is supplied from the ignition switch (on many cars this contact is equipped with a “chip”);

• when power is applied and the relay is working properly, a clear click will be heard, and the bendix will move backward;

• if the bendix does not come out, you need to disassemble and diagnose the solenoid relay.

You can also check the VR when it is removed from the starter; here we also supply power with wires from the battery (plus and minus). When “ ” is applied to the control contact, the core on a working relay will be retracted; if the VR is faulty, the full stroke of the core is not observed.

The starter contact relay (SCR), which is usually located inside the car or in the engine compartment on the panel next to the windshield wipers, may also be faulty. In this case, when you turn the ignition key, faint clicks may be heard, or more often no sounds can be heard at all. Before you start checking the RPC itself, you need to make sure that power is supplied to the relay.

It should be taken into account that each car model has its own circuit, some cars have a starter blocking relay installed (has a different purpose), some cars do not have a starter lock relay at all. You need to check the chain according to the electrical diagram, but the principle of operation, we assume, is generally clear.

Also interesting: Where is the starter relay located in the field?

The ECR itself is also checked using a test light or a multimeter, but when searching for a defect on your own, it is more convenient to have a working relay in stock, given that the part is inexpensive and is almost always available in car dealerships.

You can check the starter traction relay with your own hands using an autotester. To do this, you first need to measure the voltage from the battery at the starter contact. After this, the tester probe is connected to the starter output, after which it is necessary to turn on the ignition and turn the key to the “start” position.

During measurements, you need to pay attention to the following: if measurements at the input show a voltage that corresponds to the normal charge of the battery, but when the traction relay is activated, the voltage at the output drops 2-3 times, then there is a high probability of burning out the power contacts of the traction relay.

If the traction drive malfunctions, the starter clicks and does not turn the engine. The fact is that burnt contacts cannot transmit voltage completely due to insufficient contact.

If the input voltage corresponds to the voltage of a charged battery and a similar voltage indicator is noted at the output of the traction relay, then the contacts of the traction relay are in perfect order. This indicates that the breakdown occurred in the starter. In the first case, the traction relay should be disassembled, after which the contacts should be cleaned, and the jumper plate should also be cleaned.

Nothing irritates a driver more than the silence of the starter in response to turning the key in the ignition. There are many reasons why a car won't start.

Starting from the banal disconnection of contacts, ending with the failure of the starter. External manifestations of a breakdown can also be different, and if you know the design of the starting system, you can quickly find a weak point.

If, when trying to start, the starter clicks and nothing else happens, this significantly narrows the troubleshooting sector.

Clicks under the hood when trying to start the engine are generated by the retractor relay, which is responsible for the engagement of the Bendix working gear with the flywheel ring. Not very experienced drivers believe that such clicks can be produced by the starter relay, and they consider the solenoid relay to be the culprit of the breakdown.

If the starter clicks but does not turn, then this is not at all a reason to blame the “retractor” (as the retractor relay is briefly called), because current flows to it, otherwise there would be no sounds at all. And the starter relay makes clicks during its operation, but they are almost inaudible, so this sound cannot be confused with anything.

The starter relay is located under the auxiliary fuse box next to the ignition relay. On the VAZ 21214, the starter activation relay is attached to the injection system relay bracket.

Modification: heat protection casing

As a rule, the starting device on the Niva and other domestic cars begins to deteriorate like this. At first it is difficult to start the engine, then a whistle appears. When parked for a long time, the car does not start at all, and the battery quickly runs out. If the device is not diagnosed in such a situation, the problem will get worse. There are usually two reasons why the starter is not checked immediately:

• battery - if replaced, the battery will withstand a faulty starter for some time, and the engine will start properly;
• wires and terminals are cleaned of rust, which improves the current supply and plant, but also for a short time.

The real fault is hidden inside the starter. It is noteworthy that at this time the engine starts easily, as soon as it cools down. When hot, it is impossible or extremely difficult to spin the crankshaft. Hitting the front starter cover with something heavy helps, but for how long? Sooner or later, the starter is disassembled, and the cause of all troubles is determined.

One of the factors for the early failure of the starter on the VAZ-21213 is a coolant leak. Most car owners do not even notice how antifreeze drips onto the electrical contacts of the starter. This will undoubtedly cause over time:

• damage to brushes and bendix;
• interturn closure;
• oxidation of terminals and other unpleasant things.

Replacing brushes is easy. It’s good that Russian starters are easy to dismantle, disassemble and damage. The brush assembly is located directly in the rear cover of the starter along with the bushing - it is also worth checking at the same time. Bendix is ​​located under the front cover. To remove it, you must first release the adjusting and thrust washers, then pull out the restrictor ring from the drive.

Now about a small modification that will protect the starter not only from aggressive liquids, but also from overheating. We are talking about installing a heat shield - like the generator on the VAZ-21213. It is best to use plastic for these purposes - a regular, unnecessary 5-liter canister will do. A piece measuring 20x15 cm is cut out of it. Then it is cut with scissors according to a pre-designed shape and a protective cover is obtained, the side overhangs of which reliably protect the starter. Can be mounted with one bolt.

Often, owners of a VAZ 2121 or 2131 SUV encounter problems with starting the engine. For example, when you turn the ignition key, the starter does not turn. Let's look at possible problems with the Lada 4×4 starter and ways to solve them.

If the car does not react in any way to turning the key, you need to check the devices sequentially in the following order.

Selection of components

The original starter is produced by LADA and comes in the original blue packaging. It is marked with article number 21214-3708010-01. The cost of this part is from four to five thousand rubles, depending on the store.

To avoid stumbling upon a fake, carefully examine the box. The presence of extraneous logos, absence of an article number on the box, or color mismatch is unacceptable. The low price should alert you.

Alternative options are produced by companies such as Fenox, Krauf, Valeo. The listed brands are distinguished by high quality products and fairly affordable prices. The price for starters varies from 2200 to 4700 rubles.

What original or analogue can I supply?

If the starter does not turn, you can simply replace it. Typically, in a store, the buyer has a choice between two options:

• original;
• analogue

They differ not only in their quality, but also in their durability. The easiest way to study visual differences is in the photo.

But the cost of the original starter is usually at least 3.5 thousand rubles. That’s why many people opt for analogues. There are many other manufacturers on the Russian market that are not certified by AvtoVAZ. If possible, you should choose well-established brands.

It is important to remember: all starters have different resources and may differ in size. It is advisable to arm yourself with a ruler and tape measure before going to the store.

This will allow you to avoid purchasing a device that is not suitable in size. Some manufacturers produce equipment that can be installed on various vehicle models. The price depends significantly on the manufacturer.

Before purchasing an analogue, you need to familiarize yourself with the brand. For example, Bosch has proven itself to be good. The equipment he produces is durable and does not cause difficulties in repair. There is a list of manufacturing companies recommended by AvtoVAZ itself. It is advisable to familiarize yourself with all the nuances and subtleties of installation in advance. This will allow you to select it at the start and install it later yourself.

If the car is from 2009, then check relay No. 5 in the passenger compartment, also check the contact group of the ignition switch, the cleanliness of the contacts on the starter.

The alarm there does not have a blocking relay. This is what we still need to understand. Have you looked at the plus on the starter solenoid relay? Thin wire on the starter.

There is a lot of correspondence, but what engine is not written about. There is also no information about what year the car was made. Before the restyling there were some fuse block diagrams, after - others.

The instrument panel time and daily mileage are reset when the power is turned off. So look in this direction - why the tension disappears. Start by checking the fuses, maybe the contact disappears from time to time (not reliable contact).

So, let’s look at the main reasons why the engine may not start when “cold” below.

Topic: Resolved: Starter does not turn over when engine is warm (after driving)

Good day! The essence of the problem is that when the car is cold it starts, the starter always fires, but when you drive it (i.e. it warms up), turn it off, and start to start the starter does not work. Sometimes it starts 2 times, sometimes it takes 2 minutes to turn the key back and forth and then it locks. If the starter does not operate, the indicators on the instrument panel dim. This was done to solve the problem (it didn’t help): all the terminals on the battery are screwed on and cleaned well; The (+) wiring to the starter is also cleaned and tightly put on. I ask for help and advice. The retractors die.

Djin, look at the starter relay, perhaps the contact group in the ignition switch is also what the brain does. also the wiring of the connection point of the chips, the voltage drawdown from the poor contact somewhere, good luck in the search

The contact group is unlikely since the problem is described during heating. The relay might be worth a look. Most likely the retractor or the entire starter itself. I had the same problem, no matter how I treated it, replacing the retractor only gave a temporary effect. Disassembling the starter is the only way you will find out the reason. I struggled with money for a long time, threw away half the cost of the starter and ended up having to buy a new one. If you want, disassemble the retractor itself and look at the spots, if they are burnt, clean them, put everything back and lubricate the starter itself with oil, just don’t pour too much without fanaticism. It should work out

And who’s stopping you (when it won’t start) to apply + directly from the battery to the starter control contact (after disconnecting the chip from the ignition switch or the starter relay - depending on the year of manufacture of the car). Do this with the ignition on and the gear off. If the car starts, then the starter is normal, look for a problem in the ignition switch or wiring, or in the starter relay if there is one (most cars did not have one).

The problem is trivial and as old as the world - a hidden defect of the manufacturer - modern starters do not have a starter winding; instead, powerful magnets are installed with a small gap between the armature and the stator; when cold, during further operation this gap is masked and therefore, when the starter is cold, the armature can rotate even to some minimum level. then with warming up the gap is selected by temperature expansion and the armature jams tightly - there are two options: the first is to disassemble and wash the stator (at the same time do maintenance), if the magnet(s) are unstuck then option two. new

Brushes and winding

Inside the starter housing there are 4 steel cores (shoes) with a winding that is connected into a circuit.

Healthy! Some cars do not use cores with windings, but magnets, which is much more convenient.

The current to the winding comes from the central input, and the output is output to two copper-graphite positive brushes that go to the commutator. Also connected to it are negative brushes that come from the starter mass. All brushes are constantly pressed using small springs. But, since graphite is not the most durable material, these elements tend to wear out quite quickly. When brush wear reaches a critical level, the solenoid relay stops receiving current.

In the event of such a breakdown, the starter will not make any extraneous sounds. To repair, you will need to disassemble it and evaluate the condition of the brushes. If everything is in order with them, then we look at the windings. If they burn out, the layer of varnish that is applied to them will also burn out. Also, instead of copper color, the windings will be black.

Broken bendix teeth or flywheel ring

This problem usually appears on cars with high mileage, especially after a recent flywheel replacement or repair of the starting mechanism. When you turn the key, the starter makes strenuous attempts to start the engine: it clicks, buzzes (sometimes with a squeal), but the internal combustion engine does not start. The problem here is the engagement.

Broken bendix teeth

The flywheel teeth (on most cars) are beveled to help the Bendix gear engage more smoothly. If there is significant wear, jamming of the traction relay fork, wedging or wear of the gear itself, it does not reach the point of reliable contact and does not fit along the relief of the teeth. Slipping leads to more wear and, since the part is not repaired, to unscheduled replacement.

If, when starting the internal combustion engine of a car, any extraneous sounds arise from the starter, this is a reason to check it as soon as possible. Otherwise, he will “remind himself” on the road.

Chevrolet Niva starter does not turn - Do-it-yourself car repair

The simplest and most common problem that causes the starter to click but not turn when you turn the ignition key is a low battery charge. If the car's power supply is discharged or simply damaged, similar "symptoms" will be observed.

The engine starting system will behave as follows if the required current does not flow to the starter from the battery when the ignition key is turned:

• Nothing happens - there are no sounds, clicks or attempts by the starter to spin up. In such a situation, it is necessary to diagnose the health of the battery by turning on any consumer - radio, headlights or others;

• The dashboard lights go out and the starter solenoid relay clicks. In such a situation, the battery is almost certainly to blame;
• The starter makes a series of clicking sounds, and the lights on the car's dashboard dim slightly.

In all three cases, be sure to check the battery charge level using a multimeter or load plug. If the battery is faulty or discharged, it should be replaced or charged. When, as a result of the check, it turns out that there are no problems with the battery, it is necessary to move on to the following possible reasons for the appearance of clicks from under the hood when starting the engine.

No fuel supply

Often the engine does not start if the fuel supply system is faulty or incorrectly adjusted. Attempts to start such an engine are usually accompanied by popping noises, shots in the muffler, the appearance of black smoky smoke and a strong smell of gasoline from the exhaust pipe. A malfunction in a carburetor engine is usually determined visually.

It is enough to shine a flashlight into the primary and secondary chambers. If there are traces of gasoline on the walls, and fuel does not spray out of the accelerator pump nozzle, but flows out in a thin stream, it is necessary to urgently identify and eliminate the malfunction. To accurately determine a malfunction in an injection engine, you need special equipment that is connected to the vehicle’s diagnostic connector and is capable of reading error codes and faults.

To determine the serviceability of the injectors, you should disconnect them from the ramp, and then ask an assistant to crank the engine with the starter. If gasoline flows out of the injector nozzle in a thick stream or does not flow out at all, the injector should be washed in an ultrasonic bath or replaced.

To avoid various surprises along the way, it is recommended that you always check all engine systems before leaving, eliminating minor faults. For example, loose contact, friction of wires and hoses on various protrusions, leaks of oil and other liquids, etc.

In this case, you can not only eliminate minor breakdowns, but also identify and prevent more serious ones, which can lead to significant expenditure of effort and money. Always stay mobile. Good luck on the roads!

Troubleshooting wires

During operation of the power unit starting device, the entire load is transferred to its solenoid relay. Therefore, to the question: why does the starter click, we can answer that the relay begins to function, making characteristic sounds. This indicates a malfunction, since the starter does not work at this moment and does not turn the crankshaft of the car engine. The occurrence of such symptoms is typical for the following situations:

• short circuit or burning of the turns of the rotor or stator windings;
• deterioration of the bushings, which caused the motor shaft to jam;
• breakdown of the rotor to ground.

Without removing the device from the car and completely disassembling it, it will not be possible to detect such malfunctions.

The traction clicks due to the fact that its core moves between the retracting and fixing windings, and if the voltage on the latter is insufficient, it cannot hold on and returns to its original position. The presence of clicks is evidence of unsuccessful attempts by the core to stay in the required position.

Note that if it was not possible to start the vehicle engine the first time, this is not at all evidence of a faulty starter. It is likely that most systems have not yet started working; to do this, you need to turn the ignition key again.

In addition to the solenoid relay, burnt contacts (this is accompanied by a characteristic burning smell and, in some cases, smoke), lack of ground, disruption of the integrity of the electrical network, or a discharged power source can cause problems with the engine starting system. Elimination of these faults is carried out on an individual basis.

Some drivers, in search of a malfunction, are in a hurry to remove the starter, but such hasty actions should not be taken, since often the problem of the engine not starting is due to wires, poor contacts or their absence. Here are the most typical defects:

• low weight of the engine and body;
• unreliable connection of the starter wires (plus of the rotor winding, main plus, power supply contact from the ignition switch to the solenoid relay (SR)).

If there is a bad ground on the engine, a sign of a defect will be a slight click on the first attempt to start, then all the instruments may go out, and with the next turns of the key any signs of “life” will disappear altogether (but not necessarily). Checking the presence of mass is quite simple, but the check needs to be done by two people:

• one of the participants closes the mass terminal of the battery with the engine housing with a metal object (for example, a wrench or a cigarette wire);
• the second person, sitting behind the wheel of the car, turns the key all the way to the right;
• If there really was a bad ground, the starter will immediately start turning at normal speed.

You should also ensure the reliability of all fasteners on the starter; to do this, perform the following steps:

• unscrew all the nuts on the starter, having previously removed the terminals from the battery;
• wipe the joints and fasteners with a dry, clean rag;
• treat contacts with WD-40;
• tighten the nuts with the necessary force; do not overtighten, otherwise you may break the thread.

If the BP wire is connected using a connector, bend the tongue of the “chip”; here the connection should be tight.

When, after cleaning all contact parts, the engine starts, it means that the malfunction has been eliminated, and there is no need to find out what caused the defect. If nothing has changed for the better, then you should definitely check the starter; to do this, the unit will have to be dismantled.

If, when starting the engine, the starter makes one loud click and nothing else happens, in 100% of cases this is caused by problems in the module itself. One click indicates that charge is reaching the starter as the relay clicks. In this case, failure of the relay is excluded. The cause of the problem with the functioning of this module may be an unstable charge that reaches it.

• the starter bendix has failed;
• the retractor is broken;
• the main winding of the starter is broken;
• winding short circuit;
• brushes and bushings are worn out.

In the latter case, it is only necessary to replace the failed components.

In any case, regardless of the reason why this problem occurred, the first step is to inspect and check all contacts visible from the outside. Often the starter stops performing its functions normally due to weak contact in one or another node. An unstable charge is also a fairly common cause.

Even if you eventually managed to start the engine after some attempt, you should not consider the problem solved. Otherwise, at some point the car will simply stop starting and you will have to look for alternative ways to start the engine. You should not solve the problem by replacing the starter.

A car has long ceased to be a luxury. It’s hard to imagine life without a car these days. Many people drive a car every day and for any need - to work, study, dacha, shopping, on vacation. And that's why it becomes very bad when the car won't start. Plans are ruined, meetings are cancelled, people lose money!

We will look at situations where the starter works, but the car still does not start, another time. And now - about what to do if the starter on a Priora does not turn.

First, let's understand how a starter works and what its structure is. An electric motor with a gear that meshes with the engine flywheel and turns it when started. All this is hidden in a housing on which the solenoid relay is mounted. It is designed to move the gear and supply power to the electric motor.

When you turn the ignition key, current is supplied to the relay. Using an electromagnet, it is retracted, using a special mechanism, it moves the gear and starts the engine by closing the contacts. When the key is released, power stops being supplied to the magnet of the solenoid relay, the relay operates in the other direction and the contacts open.

If you hear clicking sounds when you turn the ignition key and the lights on the instrument panel go out, it may be the battery. It needs to be checked, recharged, topped up with electrolyte or replaced. Is the battery OK? Then the situation becomes more interesting. Check the wires that come from the battery.

Check the connection between the ground terminal and the body. If necessary, clean this connection. Check the connection between the plus terminal and the starter. Determine if power is supplied to the solenoid relay from the ignition switch. To do this, you need to disconnect the connector from the relay, and turn the ignition key “to start” and measure the voltage at the connector.

The Priora starter still won't turn? Then you will have to remove it from the car and check it.

The removal procedure looks like this: disconnect the battery terminals, unscrew and remove the air filter, unscrew and remove the positive wire from the starter. Then disconnect the connector from the relay, unscrew the starter mounting nuts and remove it. We are already much closer to solving the question of why the Priora’s starter does not turn.

You can hook the negative wire to the starter housing, and the positive wire to the lower terminal of the solenoid relay. The electric motor didn't work? The culprit is most likely the motor brushes.

Ignition

If the previous steps did not help, proceed to checking the ignition. The most common problem occurs due to moisture accumulation in the distribution cap. Do the following:

1. Remove the cover and inspect for condensation.
2. If there is one, wipe with a dry cloth. Before wiping, check the lid for cracks - if there are any, just throw it away and buy a new one.

If everything is fine with the cover, check the wires for electrical conductivity. Bring the tester to the insulation and wait for a successful outcome. It will be so if you do not detect current: with normal wires, the insulation will not allow it to pass through.

Bushings

Bushings (aka bearings) are located in front and behind the starter. They are responsible for rotating the device shaft. If these elements are worn out, the starter will start clicking, but will not turn. Problems with bushings can also be caused by the fact that the starter is installed incorrectly, that is, it does not occupy the desired position along the axis. Or the winding could short-circuit. In this case, see the previous paragraph.

Healthy! Also, problems with the bushings will be indicated by “heavy” cranking of the starter, even if the engine is well warmed up.

Although many do not consider bearing failure to be a serious failure, they need to be replaced. Otherwise, the starter shaft will jam, which in turn can cause a fire.

Description of problems with the starter and ways to solve them on the VAZ 21213

On Niva, most of the components are quite reliable and do not require frequent repairs. But there are a number of standard breakdowns characteristic of the vehicle in question. Most often, the starter does not turn for the following reasons:

• turn-to-turn short circuit in the solenoid winding - the relay needs to be replaced;
• open circuit of the power supply - it is necessary to check the connections between connections No. 50 and No. 86 (the most common places of oxidation);
• the relay armature is stuck - it is necessary to replace the armature.

If the solenoid relay is activated, but the starter does not rotate or rotates very slowly, then you must:

• poor contact on the tips and terminals of the battery - it is necessary to stretch it and clean it from deposits;
• the commutator contacts are burnt, the brushes are stuck - you need to clean the commutator and replace the carbon brushes;
• there is a short circuit in the brush holder - it is necessary to replace the cover on the commutator side.

Sometimes it happens that the starter rotates. But the engine flywheel remains motionless. Perhaps the reason lies in clutch slipping. To determine the exact cause and repair, you will need to remove the starter and check it on the stand. The problem can only be solved by replacing the coupling. Sometimes extraneous noise occurs when the starter rotates. The reasons for this may be the following:

• The bearing bushings and armature shaft journals are worn out – the starter needs to be replaced;
• The starter is loose.

To solve most problems that arise during operation, you will need to remove the starter. This procedure may require dismantling the injector. Testing at the stand will not take much time. But it will allow you to determine the exact cause of the malfunction. There is a wide range of breakdowns. They usually occur on cars with mileage of more than several tens of thousands of kilometers.

Fuel rail

On the ramp next to regulator 5 there is a control fitting 3

It is closed with a cap, which is unscrewed, and then carefully pressed on the spool

Ramp drawing

If fuel flows, it means it is entering the ramp. But perhaps the necessary pressure is not created. Reasons: clogged filter cylinder, pump malfunction, etc.

If fuel does not flow, notice whether the pump turns on when the key is turned to the “I” mark. When the ignition is turned on “cold”, the pump should run for 10 seconds.

Additional mounting block

Know that fuse F2 and relay P4 are responsible for turning on the pump. There is also a main relay P5, and all these elements are located in a block mounted on the same bracket with the ECM (see photo).

Case from practice

What happens if water gets into gasoline? In the summer - nothing. And in winter, the power supply system can become clogged with ice. All elements are at risk, from the pump to the injector valves!

Fuel supply line filter

A small amount of water is always present in fuel. If this number is increased, this is what happens:

1. The first start always goes without problems;
2. Then, after leaving the car in the parking lot, after 2-3 hours the owner will no longer be able to start the engine without repairs.

All of the above applies to any injection internal combustion engine, including the VAZ-2123. And the “first candidate for failure” will be the fuel filter. It is located under the bottom of the Chevrolet Niva and is encased in aluminum (see photo). However, this is done on many cars.

Pumping up excess air

One smart book says that the engine may not start due to the fact that the intake manifold draws in too much air. This means you need to check the fastening of all pipes. But not only.

Vacuum brake booster

The source of “excess air” may be a faulty VUT. The starter turns, the engine on the Chevrolet Niva does not start, and the reason, it turns out, must be sought in the brake system!

We won't look for anything. Let's do it simpler:

1. The vacuum supply hose is removed from the amplifier side (see drawing);
2. The hole in the hose is closed with a finger and one test run is performed;
3. The engine starts, which means the cause has been found.

That's the whole trick. We wish you success!

Gasoline pump

In order to find out whether the fuel pump is working, there is no need to go anywhere. You just need to listen a little while turning the key in the ignition. Because when the fuel pump operates, a specific buzzing noise is emitted, and if the fuel line is clogged, it will be amplified several times, which will indicate insufficient flow in the circuit.

First of all, you need to check the fuel pump terminals and the power to them. In the photo, the terminals were worn out, which caused the contact to close and the fuel pump to melt.

Mechanical problems

• Probably the most common reason why the engine cannot start is the lack of proper fuel level in the tank. This reason could be due to the driver’s lack of attention, which is unlikely, or due to a malfunction of the fuel level sensor, which could “sour” at a certain level, indicating a sufficient amount of gasoline in the tank.
• There is a blockage in the fuel pump or fuel filter.
  Not severe contamination of the filter mesh. It could be worse!
• The injectors are clogged or the gasket is broken - this problem is a consequence of the problem described above.
  These injectors had a broken gasket. They leaked air and did not allow the engine to start the first time.
• Oil and coolant levels , which could cause increased heating, and subsequently engine failure.
• The idle speed controller is faulty .
  In order to fix this device, you need to read this article. The idle speed control is secured with three bolts.

Now that we know about the possible causes of the problem, let’s look at how to specifically diagnose it and identify the malfunction.

conclusions

Having determined exactly whether there is a particular problem that is preventing the engine from starting, you can know for sure whether you can do this work yourself, or whether you will have to use the services of a car repair shop.

In most cases, you can do it yourself, since the replacement work is not complicated. An important aspect will be the fact where the work will be done, on the street or in the garage, since in the case of the latter, no natural phenomena will force you to finish the work for reasons beyond your control.
