Ok my car wasn't getting fuel so i decided to replace the pump, since i didnt know what condition it was in anyways. So i go and fire it up with the new pump and after about 5 minutes of driving it stutters pretty bad and i cant keep a normal speed. But if you shut it off and turn it back on, itll drive fine for a couple minutes before it looses power again. So i replace the filter just in case too. Right before the car starts to loose power, you can hear the pump making noise. Its almost as if the car isnt getting enough volume at high rpms, but only after a few minutes of driving. any thoughts?
