1996 GMC C1500 5.0 305 Fuel pump keeps going bad
I have a '96 GMC C1500 305 V8 that last December (2017) I
had a fuel pump go bad on it. Bought a new one at
Autozone, at first going with an inexpensive brand that I
ended up having to replace 3 times within 3 weeks. Finally
after the 3rd time I purchased the more expensive one, I
believe it was Duralast, and it ran up until a few weeks back
before going bad. I pull th pump out, replaced it because
thankfully it was under warranty and within a matter of
days it went out again. My question is, could it be any other
reason other than crappy pumps that could be causing
them to go bad as they have? The symptoms I had before it
went bad initially was at approx 50mph the truck would
sputter as if it were misfiring but seemed to idle fine when
at a standstill until it wouldn't start after letting it sit a few
days before attempting to drive around. I have good
compression, good spark and the battery has the
appropriate power to crank. One thing I did notice after
installing this last pump was the voltage gauge reading
was bouncing slightly without having the lights on but not
enough to cause the truck to turn off. I'm going to test the
fuel pressure today and see if once again the pump is bad.
