2002 GMC Sierra 1500 Q&A
2002 GMC Sierra 1500 Question: I have no clue why, but my truck keeps stalling. Why?
Everything was going normal, I drove to a store. Came out of the store and tried to start up my truck but it wouldn't start up (never had this issue before) and I just kept trying, it eventually started. I tried to move my truck, but all the lights on the instrument panel started to flash and sometimes stay on. The gauges would start off at their normal spots but then quickly all drop down to 0. The engine kept stalling, no matter what speed I was going. The truck would only run for a maximum of 1.5min. I was uncomfortable with getting it on the road (severely freaked out actually) so I parked it and got a different ride home. It was like everything just completely stopped immediately. I tried about 30-40 times to get my truck working, but I couldn't even make it halfway around a very small parking lot before it died again. - TexasCorndog
Most likely the fuel pump has failed! VERRY common problem for GM!! - pushrod
If your dash lights are acting up, I would think you have an electrical problem. A fuel pump alone will not cause a dash to act up. Check your voltage and/or grounds for good contact, make sure your alternator is not shorted pulling power away from your electrical circuits. This vehicle will run with MAF unplugged, might unplug it and see if it runs better. Just a comment. - ProfessorG
