Every morning, car owners come to parking lots and garages, wind up their iron horses and set off on the road. But sometimes the car may not start and run.
There are many versions, all sorts of reasons, but you need to establish the one that led to the refusal. Not many owners know what tool or device to check the engine on their own. In modern cars, an inscription on the reason for the failure or a special symbol indicating a breakdown will be displayed on the dashboard. In older models that do not have on-board computers, the owner's own eyes and ears act as test instruments. You need to listen carefully to the sounds that the car makes or does not make when they try to start it.
Often the reason for the failure lies not in mechanical damage to the engine, but in other, simpler reasons that literally “lie on the surface”. For example, when turning the key in the ignition lock, the instruments and control lamps must first come to life. If nothing happens, most likely the electrical circuit from the battery is broken. It happens that a loose terminal can come off the battery. Sometimes in the evening, forgetful owners leave the car with the headlights on, and by the morning the battery is simply discharged.
If the devices and lamps are functioning, but the starter does not turn the engine, the problem is rather in itself or in its electrical part. It happens that the solenoid relay fails due to moisture and dirt. When turning the key in the ignition lock, a distinct click of the solenoid relay should be heard.
If the starter rotates the crankshaft of the engine, but it does not start, then first you need to remember that the engine requires fuel to operate, which ignites the ignition system. Therefore, you should make sure that the car has gasoline by simply looking at the fuel level sensor on the dashboard. If there is gasoline, then it's time to check the ignition system. It would seem that in such a situation, service station specialists are needed with measuring equipment, since it seems unlikely to check the engine on your own. But here, too, the first steps can be carried out right on the spot. To do this, you need to open the hood and recall the operation of the ignition system: electric current from the generator is supplied through a high voltage wire to the ignition coil, and from there to the distributor (ignition distributor), which, in a certain sequence, supplies voltage to the spark plugs. It is enough to pull out the wire from the distributor and bring it to the metal part of the car, while turning the ignition key to see a spark. If it is, then the coil is working.
