Hi all, I am wondering if any of you guys ever had a fuel pump go bad on your trucks around my year, and what are some of the symptoms. Mine chugs pretty good going up hill at higher speeds and when i shut it off i can hear the pump still running for up to 15 to 20 seconds. i checked running fuel pressure and it is good. Any ideas?

fuel dont gradually go, usually they just quit and that is it....check the injectors, maybe o2 sensor, causeing it some grief..

It's not always suddenly and permanent. I have had two Suburbans where they went out gradually. On the last one, the vehicle first died while sitting at a stop light. Then it would die randomly while idling or while running fast or slow. It would always start right back up after just a few seconds. It died 3 times going to the shop to get the pump replaced, but it got there.

Like I said USUALLY they dont I wouldstill clean the injectors or check them see if they are still sparying good, or could be stupid o2 sensor causing you grief but that would give you an engine light I would think
