I recently had the problem where the car would stall while I'm driving. I would have to pump the pedal to keep it from stalling on me. I just replaced the fuel pump and filter. It worked fine yesterday. This morning I go out and drive, the car stalled once again. I feel like it might have something to do with condensation all over the car in the morning? I would like feed back on what could be the issue so I can resolve the issue. I am not a mechanic and honestly I just watched youtube videos to help with the fuel pump and filter. Thank you in advance.

 

Ok, just getting the obvious out of the way. But I'm assuming you put the fuel filter on in the right direction?

 

Another thing you may want to check into is a Vacuum leak could be a hose that has fallen off or has softened so much it leaks.
Depending on the miles the car has a plugged Catalytic converter can cause a car to stall. Or if some smart Alick stuck something in your tail pipe too.
Another thing I always check is the Air filter, not sure what you have but you might want to take a look.
I have been pleased with the K&N brand and I clean it every 2nd oil change, or 7000 miles.
Also if your Trans fluid needs changing this can make it stall or hesitate too. Check the color to make sure it is a clear Red.
