VAZ 2110 starter does not turn

The starter on the VAZ 2110 is a simple brushed DC motor, powered by the car’s battery. It should be noted that at any engine speed its power will be quite high; this parameter of collector internal combustion engines is well implemented in the unit. Even if the load on the device varies, the power level will always be the same. However, if the device works slowly or poorly, turns, clicks, but the internal combustion engine does not start when you turn the key, then you need to pay attention to diagnosing each component.

VAZ 2110 starter does not work - where to look for the problem

Problems with starter failure can occur at the most unexpected moment. Since the engine cannot be started, the problem turns out to be quite serious. But you can try to solve this problem yourself.

It is no secret that it is impossible to start a car without a starter. Therefore, his condition should always be treated with increased attention. If it was not possible to save the element, then it is quite possible to carry out the repair yourself. It will be much cheaper than going to a service station.

First, study the VAZ 2110 starter from the photo, which will allow you to get a first idea about it. Don't worry if you've never even seen this element. This is not a hindrance to understanding the device.

stator with winding;
metal sleeve installed on the back cover;
rotor with winding and lamellas;
a planetary device consisting of three gears, which are activated as a result of the influence of the rotor on them;
relay;
another element - bendix - designed to connect the axis of rotation of the unit to the crown of the injector flywheel;
directly the body itself.

As practice shows, all components of this unit are characterized by high reliability, however, in the event of a breakdown, it is necessary to completely or partially replace the devices.

Why does the starter work poorly? As a rule, in this case the reason is the wear of the brushes - in some cases you can replace them by unscrewing the worn elements and replacing them with new ones.

This is what the flywheel crown of a VAZ 2110 looks like in perfect condition

But sometimes manufacturers equip cars with disposable mechanisms, so car enthusiasts have to solder the device in order to restore its functionality. In this case, it must be taken into account that soldering with tin is undesirable, since the brushes will get very hot, then it is more advisable to resort to the method of welding copper wires with current.

Problems with the starter itself

So, we have considered the main external causes and ways to eliminate them. Now let's look at possible problems that may arise in the starter itself. First, let's recall some of its features. On the VAZ “tenth” series, the manufacturer installs a starter with a gearbox. The design also provides for the presence of a planetary reduction gear, which, in turn, consists of gears (ring, internal and central) and a carrier connected to the transmission shaft.

If the starter engages, but a rough noise is heard, this may indicate wear on the gearbox gears. The problem can be resolved quite simply. The gearbox should be disassembled and the satellite gears replaced. One point worth noting. Most often, the needle bearings on which the gears rotate wear out.

When the gearbox wears out, the production of other parts accelerates, and significantly, for example, due to vibration, the liners in which the drive shaft rotates fail much faster than expected.

At this point you need to pay special attention. Over time, the liners can become so loose that the starter does not operate due to a jammed shaft.

In addition, as a result of the resulting vibration, the Bendix gear quickly deteriorates. And it doesn’t just end there. The damaged gear begins to gradually destroy the flywheel teeth. To prevent this, the bushings should be replaced as soon as possible.

If the flywheel crown is worn out sufficiently, this will also bring certain problems to the car owner. In this case, the engine will start, as they say, every other time. The starter works, but you will also hear extraneous noise, indicating a malfunction. Sometimes the ring wears out to such a state that the gear simply cannot fit in and connect with it normally. However, if the flywheel turns even a little, the starter will be able to turn it half a turn. In most cases, this is enough for the car to start.

Wear of the starter brushes is another problem in which this unit will fire every once in a while. By the way, sluggish scrolling also indicates the presence of this problem. When compared with other starter components, it must be emphasized that the brushes here wear out quite quickly. As a result, a moment comes when their length is no longer enough to touch the collector. Because of this, the engine will not spin up.

The starter may also fail to operate due to a short circuit in the rotor winding or its breakage. This malfunction is very dangerous for all electronics. Moreover, a short circuit is quite possible, which can damage the battery. There are even cases where the battery simply exploded. If the starter winding is shorted, you will hear a distinct burning smell in the engine compartment. There is no point in doing repairs here - it is better to just buy a new one. Otherwise, you risk wasting time and money, but repairs in any case do not provide any guarantee of subsequent long-term operation. It is possible that after some time the problem will appear again. Therefore, in this case, it is better not to save, but to immediately replace the starter, because the stingy, as we know, pays twice.

VAZ 2110 starter stopped turning, where to start repairs

Before disassembling the starter, it is necessary to check the serviceability of the wiring and some components. Perhaps the problem lies with them.

First of all, check if the battery is charged.
Then, using a tester, check whether voltage is supplied to the auxiliary relay terminal.
It is also necessary to check whether power is supplied from the ignition switch. To do this, remove the connector from the relay, connect the tester and turn the key to start. When you turn the key to this position, power should appear at the connector.

If no malfunctions were identified during this check, and the starter on the VAZ-2110 still does not turn, then it is necessary to remove it and determine the cause of the malfunction.

Instructions for replacing the unit yourself

If you decide to repair the unit, you should understand that most likely this will only help for a short time. The thing is that the constituent elements of the starter usually wear out evenly. Therefore, if you replace one part, you should understand that in the near future you may have to change other elements.

In VAZ 2110 cars, the procedure for dismantling and installing a new starter looks like this:

First, turn off the ignition and open the hood of the car. Disconnect the terminals from the battery, otherwise you may accidentally short-circuit the mechanism when removing it.
Next, if you have an injection engine, you will need to remove the air filter housing. Having done this, you need to unscrew the three nuts that secure the assembly.
Before removing the device, the power cable should be disconnected from the relay. Also disconnect the thinner wire; having done this, the unit can be removed from the car.
Actually, at this point the removal procedure can be considered complete. If you decide to carry out repairs, then all you have to do is disassemble the unit and identify the failed elements, and then replace them. Before assembling, clean the device and make sure that all its contacts are intact. If you are changing the unit, simply install a new one instead of the old starter; further assembly is carried out in the reverse order.

Malfunctions and methods for checking the VAZ 2110 starter retractor relay

You got behind the wheel, turned the key, the instrument panel turned on, and the fuel pump started working. You turn further, but the panel turns off and the starter is silent. You release the key, the panel lights up again and the fuel pump starts working.

First of all, check if there is voltage going to the solenoid relay. Is it coming? Try closing the starter. Refuses to turn? Disconnect the alarm system, it may also be the cause, just like the ignition switch of the VAZ 2110 itself.

Burnt contact of the starter solenoid relay VAZ 2110

Have you discovered that everything works in “independent mode”, but together it fails? This means that the solenoid relay is faulty and should be replaced.

This component of the system is a simple electromagnet.

This electromagnet includes:

the body itself, made of a non-magnetic base;
the so-called anchor, which is also a magnet;
winding installed in the device body;
two copper contacts, as well as a plate that closes them.

As for the principle of operation, it is quite simple. Two wires are supplied to the relay - from the battery and from the ignition switch (voltage appears on this wire only if the key is turned all the way).

When the driver releases the key, the voltage disappears. During the generation of voltage, the relay begins to operate, and the winding inside it is under the influence of voltage. As a result, the attraction of the so-called armature occurs, which subsequently begins to act on the rod located in the lower part of the electromagnet.

VAZ 2110 starter retractor relays in a box

This rod is directly connected to a jumper designed to close the contacts when voltage appears. At the same moment, the gear moves relative to the mechanism pulley. As a result, voltage begins to flow to the windings of the electric motor, as a result of which the flywheel rotates, and with it the crankshaft of the VAZ 2110 engine begins to rotate

What could happen to electrical equipment?

If there is something to burn in the working cylinders, then you need to look for what will make the mixture burn

This means that you need to pay attention to the car's ignition system. This could be an ignition distributor, a high-voltage coil and wires, spark plugs. It doesn’t happen that all devices fail at the same time, so we should talk about them separately

It doesn’t happen that all devices fail at the same time, so we should talk about them separately.

We will assume that the distributor is installed correctly; in this case, a failure may occur through a breakdown of the cover or slider, or a failure of the Hall sensor. However, most often the cause is poor contact in the power connector of the ignition distributor. An ignition module or coils that do not produce high voltage to produce a spark at the spark plugs can create problems.

Injectors work in conjunction with ignition modules, of which there are usually two per engine. One ensures the operation of cylinders 1 and 4, and the second - cylinders 2 and 3. In these systems, the electronic control unit, which generates control pulses for all systems, including the ignition, may be problematic. This block can only be checked by replacing it. The same can be done with ignition modules.

Sometimes the fault may come from the high voltage coil. it does not generate voltage that can create a spark to ignite the air-fuel mixture. You can check its operation if you unscrew the spark plug from the cylinder and, together with the high-voltage wire, ensure its contact with the engine ground. At this time, you need to crank the starter and watch the spark plug. The absence of a spark confirms that the ignition coil is faulty.

It is impossible not to dwell on such elements of ignition systems as spark plugs. They are the ones who ignite the combustible mixture in the working cylinders of the engine. During their operation, the metal parts of their electrodes burn out, after which the gap increases, starting the motor becomes more difficult, or even becomes impossible. Check the condition of the spark plugs regularly, especially their gap. then problems can be avoided.

You can continue to review situations when the starter turns, but the VAZ 2110, 2112, 2114 does not start. It is simply impossible to take into account absolutely all cases, but to avoid such situations, carry out routine maintenance of the machine in a timely manner, use only high-quality operating fluids.

VAZ 2110 won't start, the injector turns the starter

Probably every motorist has encountered a situation in which your car does not start, and there is little pleasure in it, especially if it happens on the road.

To begin with, it is recommended to conduct a general diagnostic of the engine and try to identify the malfunction. In this situation, in order to determine the malfunction of the VAZ 2110 power plant, it is recommended to check all operating systems of the engine, proceeding from general to specific.

The blender or crown of the VAZ 2110 is faulty - how to check

Bendix is a device consisting of two parts - an overrunning clutch, as well as a gear, which is located directly on it

It should be noted that the overrunning clutch is directly connected to the starter pulley thanks to splines installed in a spiral. The mechanism moves along these slots when the driver tries to start the engine.

If the starter does not click and does not work or works slowly even when hot, the problem may lie in the bendix. In addition, there is another fork on the device, consisting of two metal plates mounted directly on the overrunning clutch. This fork is attached to two opposite points of the element. One of the edges of the plates is made in the form of a rectangle.

When the driver turns the key in the ignition, the retractor relay acts on these plates. Next, the gear moves along the pulley using splines until the element engages with the flywheel rim.

Doesn't start well and boils

In this case, the reason lies in the coolant. Check its level. If necessary, dilute with distilled water. However, there is no need to mix different brands of antifreeze. It may foam, which will further accelerate overheating.

The thermostat may also break. The VAZ 2110 8-valve injector is equipped with a two-piston element. It's very easy to check. To do this, you need a burner and a pan of water. Place the thermostat in the container and wait for the water to boil. If bubbles appear and the piston does not move, it means the element is faulty. The temperature at which it should operate is indicated on the metal body of the thermostat. The element cannot be repaired - it must only be replaced. As a result, the system is unable to regulate the operating temperature of the antifreeze. The coolant moves only in a small circle. But the car may start poorly (every once in a while) due to an incorrectly adjusted ignition. Most "ten" cars have a distributor ignition. Here you need to set the correct lead angle.

Checking the overrunning clutch of the VAZ 2110 starter

A cold engine starts without the slightest problem. You are driving quietly, stopping somewhere - to go to the store or for other matters. You return a few minutes later and are faced with a problem: the starter clicks, but refuses to work. And only after the engine has cooled down the car starts.

The first culprit in this situation is the overrunning clutch (popularly called Bendix, from the name of the well-known manufacturer of this part). It is better to replace it with a gearbox.

But you check and there is no malfunction? The next line is the wires going to the battery. Examine them carefully. It is quite possible that replacing the wire will solve all the issues.

Starter VAZ 2110 disassembled

There may be another situation: while on the road, the radio starts to turn off spontaneously, despite your attempts to turn it on. Having stopped to look and turned off your VAZ 2110, you soon discover that you cannot get the starter to crank. We checked the battery, everything is fine, but the car, which previously started normally, suddenly struggles.

You start pushing, and it works, everything works again. Almost certainly the problem is in the Bendix.

Step-by-step instructions for replacing the VAZ 2110 starter

In order to remove and replace a faulty VAZ 2110 starter, you will need to perform the following procedure:

Remove the negative terminal from the battery
Disconnect the control wire of the traction relay.
Read also: Battery does not light up when ignited: causes and solutions
Remove the positive terminal of the starter using a key at “13”
Unscrew the mounting nuts securing the starter to the clutch housing.
Removing the starter
Using the “10” socket, unscrew the traction relay output nut.
Next, remove the wire end.
Then, using the “8” socket, unscrew the mounting bolts of the traction relay and remove it.
At the very end, the gasket is removed, which seals the connection between the front cover of the starter and the relay.
Remove the traction relay armature and spring from the front cover.

Where and how to buy?

You can select a starter based on the unique number of an existing model or based on its technical characteristics. The correct starter with a 1-year warranty can be purchased at any specialized auto store or ordered online. Purchasing from an online store is accompanied by a lower price, but the absence of a stamped warranty card. Therefore, it is important to insist on receiving not only a sales receipt, but also a fiscal receipt. It is the latter that will determine the actual date of putting the starter into operation.

You can order a starter at an official VAZ dealer, but only an original one, the price of which will be at least 8,500 rubles . In this case, the dealer provides a discount on installation.

Almost every car owner of this, in principle, the best car in the domestic automobile industry (let alone the worst!) can encounter a situation when suddenly the starter of a VAZ 2110 does not turn. But, as you know, if you don’t start, you won’t drive, which means you need to, firstly, find the reason why the starter still refuses to turn the engine, and secondly, eliminate the detected faults.

New starter for VAZ 2110

Let's try to follow the path of looking at symptoms and finding solutions.

VAZ starts and immediately stalls

The car may stall immediately after starting, even due to trivial little things such as consumables. Therefore, first of all, I advise you to check the fuel and air filters. If they are clogged, it is difficult for the engine to receive oxygen and fuel, which causes it to simply stall.

If before your VAZ stopped starting, the following were discovered:

Power Loss
The car doesn't start well
Increased fuel consumption

It is most likely that the catalyst that is equipped with VAZ injection models is faulty. The catalyst can be removed by flashing the engine control unit. As an alternative: install lambda decoys. A clogged catalyst may also be the reason why the VAZ does not start.

When the solenoid relay is at fault

Have you discovered that everything works in “independent mode”, but together it fails? This means that the solenoid relay is faulty and should be replaced.

When the immobilizer is a hindrance

The engine stalled unexpectedly, the starter refuses to turn it, and it also won’t start with a “push.” The battery was checked - charged, serviceable, terminals clean and in place.

However, your immobilizer is working, and most likely the problem is there. The protection is triggered, the engine is silent. It is necessary to tow the VAZ 2110 to a car service center for diagnostics.

In order to bypass and disable the immobilizer yourself, it is recommended that you read the following article: https://vazweb.ru/desyatka/elektrooborudovanie/kak-otklyuchit-immobilayzer.html

The overrunning clutch has failed

The first culprit in this situation is the overrunning clutch (popularly called Bendix, from the name of the well-known manufacturer of this part). It is better to replace it with a gearbox.

But you check and there is no malfunction? The next line is the wires going to the battery. Examine them carefully. It is quite possible that replacing the wire will solve all the issues.

You start pushing, and it works, everything works again. Almost certainly the problem is in the Bendix.

Types and prices

models of starters were optionally installed on the VAZ 2110 , most of which found application after installing a 16-valve internal combustion engine in the car. They also differ in design and type of service. Therefore, now you can choose and buy the following starter models:

3708000 – RUR 3,452.
3708000-01 – 4,760-8,551 rub..
3708000 – RUB 4,659.
3708000-01 – RUB 4,170.
3708010-01 – RUB 5,897.
3708000 – RUR 3,940-6,200.
3708000 – RUB 4,380.
3708000 – RUR 4,070.

Starter models with a lower price are optimized for the existing flywheel crown. Previously, they were installed, until 2007, on bodies of the 2105 and 2107 brands. They have enormous maintainability. Replacement of brushes takes place in just a few movements with complete removal of the product from the car.

The indicated price is recommended for retail sale and, for the most part, is respected by stores and online platforms. The actual price may differ upward by no more than 7-10%.

No contact

The starter starts with difficulty, before clicking. At first you are only slightly alarmed, but the situation repeats itself again and again: first it clicks, and only then the engine turns.

Have you checked your contacts lately? You need to start with the battery, maybe you are wrong to blame the starter, and the reason is oxidation of the terminals. Have you cleaned them and the starter clicks again? You need to check how your VAZ has ground contact with the body, and then the contacts of the starter itself, because they are also prone to oxidation.

Another test method: ask someone to turn the ignition key, while you yourself knock on the relay, using only a hard object. If it starts, it means that the closing contacts (nickels) are stuck, and it is easier to change the relay than to disassemble and repair it.

What does the price depend on?

In addition to such a pricing factor as the brand, especially in relation to VAZ branded products, the retail price is influenced by:

Starter type.
Model.
Rated power (kW).
Nominal voltage (V).
Gear module (mm).
Number of gear teeth.
Weight (kg).
Compatible battery capacity (Ah).

The final price of the product is minimally affected by the configuration of spare parts:

Cover s/p.
Cover s/k.
Brush holder equipped with brushes.
Relay cover.
Brushes.
Relay coil.

The injector can also fail

In fact, we have sorted out almost all starter malfunctions associated with the operation of the VAZ 2110 carburetor engine. There are also injection engines, which are fashionable to install on cars today. Yes, they are more environmentally friendly, reduce fuel consumption, increase power performance, and the engine does not require warming up in winter.

But the injector is unlikely to “rejoice” at insufficiently high-quality gasoline; its repair is more expensive, since it operates under the control of a microprocessor. And in our operating conditions, this can also be the reason why the starter does not work well. Perhaps the injector requires cleaning (and this should be done regularly, since low-quality gasoline contributes to the deposition of resins and impurities).

We looked at the main faults of the VAZ 2110 starter, but not the only possible ones. If you monitor the operation of all components and devices on the car and respond in a timely manner to even minor failures, then your starter will properly turn the engine, the car will start, and you will travel for pleasure.

Checking spark plugs and sparks

If the engine does not start within five seconds, there is no use turning the starter. You can try to start it again, but it’s unlikely to help. Moreover, operating the starter for too long can lead to overheating and even fire.

If you try to start a carburetor engine for a long time, gasoline will flood the spark plugs and make further starting attempts impossible in principle. The injectors have a purge mode, so the spark plugs can be dried without removing them from the car - you just need to press the gas pedal to the floor and turn the starter.

Clean working spark plugs VAZ 2110

But these are half measures. First of all, you should unscrew at least one spark plug, put the wire back on it and position the spark plug on the engine so that there is a distance of about three millimeters between the metal part of the spark plug and the metal of the engine. Turn on the starter and make sure that there is a uniform spark between the spark plug contacts.

Checking the spark in the spark plugs of the VAZ 2110

Do this check for each candle. If there is no spark on any spark plug, then there are global problems in the ignition system.
