2000 Regal. Have had to replace fuel pump 4 times in the past 5 months. Also
replaced Relay. Mechanic says that power is at the pump, but after a couple
of weeks after replacing, I get a problem where it will intermittently won't
fire. I can tap the bottom of the gas tank with a rubber mallet and it will
start working. Using CarQuest brand pumps which have been sent back to them
for testing to see if there is indeed a problem with the pump, but haven't
Anyone have suggestions
Just worked on an old LeSabre with this very same problem. The owner had
put in a fuel pump from either NAPA or Advance Auto and it took three pumps
before coming up with one that worked. The DOA pumps all worked for a brief
time (mere hours) and then displayed intermittent pumping on ignition on.
No one wants to suspect three bad pumps, so you look at every other possible
cause, but damn it - it was three bad pumps from the store. QA just isn't
what it used to be...
I've heard numerous stories of multiple pump replacements on GM
cars, and nearly every story I've heard involved aftermarket pumps.
Can only think of one time I've heard of multiple failures when
original was replaced with OEM GM pump assembly.
