What causes an engine to stall while driving?
If the engine stalls while idling or driving, the engine may be running out of fuel. This could be from not receiving enough fuel pressure to keep it running. The most likely cause of this kind of stalling would be, a fuel pump that is not spinning fast enough; or is intermittently cutting out.
What to do if your fuel pump is failing?
Accelerating requires more fuel, forcing your fuel pump to work harder. If your pump is failing, it may not be able to keep up with this increased demand, starving your engine of fuel as it tries to accelerate. If your car acts like it’s about to stall when you try to accelerate from a stop, you may need to have your pump inspected. 3.
How can you tell if your fuel pump is dead?
Of course, there could be other explanations for your engine’s failure to start besides a failed fuel pump. To confirm that your pump has failed, check the pressure in your fuel lines with a fuel pressure gauge; if it reads zero, then your pump is likely dead.
