My fuel pump seemed to stop working last week-truck starved for fuel and died. I replaced the pump, and it worked great for a week. Tuesday night it did the same thing and cost my boss a huge tow fee. I have replaced the fuel pump relays behind the dash. The pump is damn near brand new. The emergency shut off is not popped up. I have a pre-pump Dahl filter and a fuel pressure gauge on the test port. Nothing. I drained the Dahl, and it was siphoning off the tank as usual-so I've got good, tight flow from the tank. Now the fuel pump won't do anything. What else could it be-just a bad wire, connector or what. When it first did it, I got P0231-fuel pump secondary circuit low. I haven't been able to get it to another code reader to see if anything else comes up. Could my ECM be bad? Help, I need this truck tomorrow night. I'll try to check some wiring with a multi-meter.
