There are many reasons for a sudden engine stop while driving or idling. This is a malfunction of the ignition or fuel system, and untimely oil change, and low-quality gasoline. But most of the breakdowns can be eliminated with your own hands at minimal cost.
Instructions
Step 1
The ignition system is one of the causes of engine malfunction. The most common malfunction in this assembly is the coil. It is quite simple to check its serviceability, to do this, turn the key in the ignition lock, connect one end of the wire with the test lamp to ground, and touch the other end to the unnamed terminal. If the control lamp starts to light up on contact, then there is an open circuit in the primary winding. Consequently, the coil must be replaced. Broken wires and poor insulation of the ignition system can also cause the engine to stall.
Step 2
The engine power system is a reason that should be given special attention. If some parts are defective, your repair costs may increase significantly. One of the reasons for stopping the engine in this case may be a clogged fuel filter. The solution to this malfunction is simple - to replace it. And so that this never happens again, change the fuel filter at least once every six months or after seven thousand kilometers of the car's run.
Step 3
The problem of stopping the engine of a car can also be in a breakdown of the gas pump. It can become unusable if the driver tries to start the engine with an empty gas tank. It is strictly forbidden to do this, since the gas pump should only work when there is fuel in the tank. A clogged coarse filter is also a fairly common cause of a malfunction of the engine power system. On most vehicles, it is located under the rear seat and is easy to remove. If it is heavily contaminated, flush it with the same gasoline or other means designed to remove contamination from engine parts. Then, if there are no deformations on it, install it back.
Step 4
Due to low-quality fuel, the idle speed sensor may also fail. When using poor fuel, carbon deposits form on parts, which can lead to improper engine operation and uneven idling. Such a malfunction must be eliminated by flushing the entire throttle assembly and changing the gas station where you buy gasoline.
Step 5
Untimely oil change can also be one of the reasons for engine shutdown. When the oil begins to lose its viscosity, the friction force in the parts of the crank mechanism increases, which leads to severe overheating of these parts and engine shutdown. In this case, it is necessary to urgently change the engine oil.
