If, when you try to start the car, you hear the starter working, but the engine does not start, then you are dealing with some kind of malfunction. There are only a few most common types of machine breakdowns of this kind.
The first thing that falls under suspicion in the case when the engine refuses to start is the absence of a spark, with the help of which the fuel mixture is ignited in the combustion chamber. The presence of a clear smell of gasoline in the interior of the car can help to make sure that this guess is correct. A defect in the ignition system can be the result of damage to the insulation coating of the wires located in the engine compartment of the car, or be associated with the failure of the spark plugs. The problem may also apply to the electronic component of the automotive ignition system. Self-diagnosis of such malfunctions is quite dangerous both for the machine itself and for its owner. The list of possible defects in this area includes problems with the ignition distributor, actuators or the failure of any internal sensors. Another reason that the engine refuses to start may be a breakdown of the vehicle's fuel system. Often it is caused by contamination with impurities of low-quality fuel. In this case, the fuel line system becomes clogged and gasoline stops flowing into the injection system. To solve this problem, it is necessary to disassemble the engine and perform a complete purge of the fuel line. To avoid blockages, use quality fuel that does not contain emulsions and other impurities. Also, the fuel pressure regulator in the engine may fail. The car in this case will not start due to the low level of pressure required for the injection of the fuel mixture. But even if the car can be started, the engine's efficiency will be significantly lower, which will lead to a decrease in power and an increase in fuel consumption.
