I have a preowned 2005 Chevrolet Silverado 1500 the owner says it was a bad fuel pump I replaced same problem
1 Answer
Did you check voltage and ground, engine cranking, for the fuel pump before you replaced it? Are you missing anything else? Engine cranking, you have spark at the plugs and fuel injector pulse? If your missing everything, check for rpm signal, comes from crank sensor. Don't replace anything unless your testing points in that direction. Any applicable trouble codes?
