ACDelco.I'm curious, what brand/model fuel pump did you have, and what did you replace it with?
AC Delco GM Genuine Parts MU1745 Fuel Pump Module Kit with Sender
Did this job recently. So far, so good. I did notice the new pump is much quieter than the old one during priming.
It's no better at Carquest, Advance, NAPA, etc.I try to stay away from orottens orielys . too many crappy parts.
check to see if your truck has a hot cycle fuel module (small black box w/ 3-4 wires) behind glove box close to ecm.I have a 91 K1500 RCSB with a 350 and a 5 speed. Last week it started stumbling and stalling. No codes. So I assumed the fuel pump was failing. I replaced it and the filter. It ran good until yesterday. About 700 miles on the new pump and filter. It started loosing power like it was starving for fuel. I got a CEL with codes 24 and 44. It can't rev above 2300prms. I shut it off at a gas station and tried again after a few minutes and it ran good for about 20 miles. It then ran good for another 20 miles or so. I repeated this until I got home. about 130 miles total. I went through the TBI about a year ago with new filters on the injectors. But did not replace them. Should I be thinking the fuel pump relay? Maybe injectors? I plan on testing the fuel pressure this weekend. But It ran good for the the twenty miles each time. Any help would be appreciated.
Turns out is was a bad fuel pump. I replaced it with a Delphi and it’s ran great for 2 years now.check to see if your truck has a hot cycle fuel module (small black box w/ 3-4 wires) behind glove box close to ecm.
