It seems that after my truck sits for a few hours or more that when I turn the ignition on that the fuel pump on the frame will run for up to like 15 minutes before shutting off so that the truck will start. When truck starts it runs great. I have replace the fuel pump relay and the eec relay (or which ever relay is next to the fuel pump relay) I used FOMOCO relays. These didnt seem to help. I have been told its the computer, the fuel pump, tps, fuel pressure reg, and so on. I s there a plan of attack to use in this situationand if so what is it or if you know what it is that would be a great help.
have the same problem?
