Why does a car start and then stall?
1 Answers
Reasons why a car starts and then stalls: 1. Throttle failure: The throttle is blocked or severely carbon-deposited; 2. Issues with the ignition coil or spark plug: Excessive spark plug gap can cause the car to stall; 3. Fuel injector failure: Blocked fuel injectors lead to insufficient fuel supply and stalling. Problems in any part of the fuel system, ignition system, or intake system can cause this phenomenon. If the car stalls even when the air-fuel mixture enters the cylinder normally, it is highly likely that there is a fault in the ignition system. The role of the ignition system is to generate a sufficiently energetic spark between the electrodes of the spark plug in accordance with the working sequence of the cylinders.
