Faults VAZ-2110: there is no spark. Injector 8 valves: possible causes of the problem

All possible breakdowns of VAZ-2110 vehicles are conventionally divided into three types. These are problems in the fuel supply system, various failures in electronics and electrical, as well as more global troubles (ICE, box). If the car has problems in the ignition system, then immediately diagnose - the spark is gone. Let's look at why the VAZ-2110 does not have a spark (injector, 8 valves). So, what are the reasons for this malfunction?

Possible reasons for absence

Most modern cars are equipped with a multitude of sensors. They make life easier for the car owner and complicate repairs. In the electronics responsible for the operation of the injector engine, there are several sensors responsible for the sparking process. But the reasons that there is no spark (VAZ-2110, injector, 8 valves), may be in other nodes. There are several types of possible breakdowns. The first can be attributed various problems in the fuel system of the car. This includes malfunctions in which fuel can not enter the cylinders or the supply fails.

If there is no spark (VAZ-2110, injector, 8 valves), then this may be due to the fuel system. The pump relay or the immersion element itself often fails. The audit is performed "by ear".

Next are the problems associated with the electrical part. This is one of the most common faults. With such breakages, an electric discharge does not come to the candle. Naturally, the mixture will not be set on fire. Among the global problems is a complete engine failure, a belt break. It is not necessary to dwell on these faults.

Methods of diagnosis

Why did the spark disappear (VAZ-2110, injector, 8 valves)? The problem should be clarified as thoughtfully and in several stages. And to find the cause was successful, you need a multimeter, as well as an arrester.

Stage One

Usually the symptoms of the problem are as follows: the starter rotates regularly in its standard mode, and the engine does not want to start. One of the most likely causes is a gasoline pump that does not start. By the way, on the injector "tens" it is submersible and is placed directly in the tank.

You can check the element by the presence of a work sound. Turn on the ignition - there must be a buzz in the area of the rear seats. Sometimes it is absent. In this case, check the fuses. VAZ-2110 is an injector auto, and the fuse box is located on the side of the center console from the front passenger side. It is necessary to unscrew the fasteners, then remove the cover, check the fuses for operability and replace them if necessary. If the elements are fully operational, then you need to check whether the relay, both the main and the fuel pump, will turn on. The moment of inclusion can be felt with a finger. You will also hear a characteristic click.

If the gasoline pump is functional, check the presence of fuel in it with a manometer. If there is no pressure gauge, then press the spool at the end of the fuel rail. This element may be in the protective cap. The pressure will be quite noticeable, although its power will not be determined. Operating pump and absent pressure can talk about the obstruction of the fuel line. This can be caused by a clogged fuel filter.

Stage Two

If there is no spark on the VAZ-2110 (injector, 8 valves), the spark plugs are often the cause. Naturally, they are checked if the gasoline pump works. It is best to use a surge arrester for testing. If the current is distributed into two candles, then there must be a breakdown "into mass".

A variant is possible, when there was a wire break on the ignition coil, or tears appeared on its winding. If the car VAZ-2110 does not have a spark (injector, 8 valves) on two wires, the reasons can be in the idle ignition coil or controller. In two cases, there is a risk of rupture of high-voltage wires. This option should be checked first. They look at the resistance level. Normal values are up to 200 kOhm.

Module and ignition coil

Here you can check the error codes that are in the car's memory. If the ECU does not have a diagnostic function, a known-good module should be installed.

Find out why there is no spark on the VAZ-2110 (injector, 8 valves), it is possible on the faulty controller. It is also possible to break wires from the controller to the ignition coil. If there is no spark on each of the coils, you should make sure that you have enough power. If there is no electric discharge for some reason, then the element must be replaced. The ignition module works in the system. Therefore, a superfluous operation will be a check for "minus".

Possible errors of the VAZ injectors

Codes can signal the failure of any parts and components in the car. Most often this is due to sensors. Particularly affected by temperature sensors - they overheat. Also motorists complain about injectors. Problems arise because of breaks in the chain. As a result, they can not work in time. This also includes a popular breakdown on the VAZ-2110 - there is no spark. Injector 8 valves can not be properly wound because of this.

Now about the errors associated with the engine. The most frequent of them is overheating. Also the candles are overheated, so the spark disappears. As a result, the motor does not show any signs of life. Next is to consider the valves. These parts can be too polluted, which will result in their complete closure. They do not pass the necessary mixture of air and fuel. And finally, fans - if they do not work, then the power unit will constantly overheat.

Other malfunctions

If the starter does not rotate, the spark disappears between the ignition switch and this element. Often this happens with a discharged or defective battery. The normal battery during the test shows no less than 11.8 V. The faulty ignition larva will appear immediately at the moment when the driver inserts and turns the key. If the turn of the key is too light or too heavy, you need to replace the lock. A starter relay or ignition system is also one of the possible reasons for the absence of a spark. But you can not check these nodes yourself. The starter can wedge the "retractor" device. In this case, the spark disappears along the way. Car enthusiasts with experience hit the starter with a key or a hammer to return the spark. But this is only relevant in the field.

What if the spark in the VAZ-2110 vanished? Check the starter in the garage using the battery. If you press the case of the device to the "minus" of the battery, and the "plus" wire is pulled to the "retractor", then the device comes to life. Often the spark may disappear where the starter is fed. This circuit is best checked with a multimeter. One can not cope here - the assistant will work as a key at the moment of performance of measurements.

Conclusion

When the spark ignited on the VAZ-2110 (injector), what's the reason, it's difficult to determine at once. Perhaps the problem lies in the banally oxidized contacts. In some cases, the situation can be corrected by cleaning the terminals from the oxides. Especially pay attention to the wire from the mass that goes to the battery. In 80 percent of cases the problem with a difficult start is solved in this way.
