What are the reasons for a car stalling due to insufficient fuel supply?

[CharlieMarie]

The reason for a car stalling due to insufficient fuel supply could be poor fuel quality. Below are the related explanations: 1. Poor fuel quality: Generally, this is due to the fuel quality being too poor to meet the required heat value. Long-term use of inferior fuel can lead to premature aging of the spark plugs inside, causing the spark plug gap to widen and resulting in damage to the fuel injector. This can cause the engine to misfire, leading to stalling at idle. 2. Additional information: A typical fault where the car must be started by pressing the accelerator is when the battery voltage and starter operation are normal. However, the engine cannot start unless the accelerator is slightly pressed, or there is difficulty in cold starts. This may be due to faults in the throttle body, idle switch, water temperature sensor, intake air temperature sensor, etc. Another possible reason is the use of poor-quality fuel in the car, which does not burn effectively in the engine.
