I think my fuel pump is on the way out. Sometimes the car runs fine, and then all of a sudden it will stall and i wont be able to get the revs above 1500. if i just leave of the gas it is okay. Does anyone know what this is? please help!!!

thanx 92rsq8

 

If you still have a Cat. I would check to see that it's not plugged. Look under the car at night with the engine warmed up, see if it is glowing. Its been my experience with Fuel pumps, when they go, they go.

A little more info on the car would be helpful..

 

Before you get all excited about the fuel pump, don't overlook the fuel filter. If it has done what it is supposed to do, it may be clogging.

Testing the pump pressure would be a good idea. A vacuum reading would be a good indication of the condition of the cat and exhaust.
