Why does my car stall when the accelerator pump is not working?
Why does my car stall when the accelerator pump is not working?
The sputtering is caused by the lack of fuel that is supposed to be provided by the accelerator pump when throttle is rapidly pressed. In more serious cases of accelerator pump failure, rapidly pressing on the gas may cause the engine to stall, again due to the lean condition that can be created when the accelerator pump is not working.

Can a faulty fuel pump cause a car to not start?
Faulty fuel pump: The fuel pump moves fuel from the gas tank to the engine. If the fuel pump is malfunctioning, the engine will be getting less fuel than necessary, which will lead to performance issues, and ultimately cause the vehicle not to start.

As you might expect, a similar phenomenon occurs when there’s not enough fuel getting into the cylinders. In this instance, the most common point of failure is the fuel pump, which is responsible for transporting fuel from your gas tank to the motor. If the pump fails, nothing happens when you press the gas pedal.

Why does my car stall when I put the accelerator down?
When an idle control valve becomes contaminated or stuck, it may lead to an unsteady and rough idle. The car will stall if the valve is too clogged or when it finally fails. If, while holding the accelerator pedal down, a small amount of pressure keeps the car running at a stop, the idle control valve may require attention.
