What Causes the Engine to Stall While Driving?
1 Answers
The main reasons for the engine suddenly stalling while driving are as follows: 1. Fuel system failure. This includes fuel pipe rupture, fuel pump failure, fuel exhaustion, or clogged fuel inlet. 2. Electrical circuit failure. A short circuit in the low-voltage circuit causing power interruption, issues with the ignition switch, starter malfunctions, or blown fuses in the fuse box. 3. Ignition component failure. Faulty ignition coils, ignition modules, or spark plugs can cause the engine to start but stall after a while, then restart and stall again. 4. Misalignment or breakage of the engine belt. Over time, belts can age and loosen, leading to breakage or misalignment that causes the engine to stall. 5. Lack of driving skill. Automatic transmission cars generally do not stall, but manual transmission models require proper clutch and throttle coordination. Sometimes, if the car speed drops and the driver does not downshift, staying in a high gear instead of shifting to a lower one, the car may stall.
