'85 720, 2400 eng., auto trans, std. cab.
Orig. prob, no fire to fuel shut off solenoid, couldn't idle.
Solved by baring spot on red solenoid wire and soldering un-needed choke heater wire to it.
Runs OK now, key switch wont kill ignition.
Unplugged the black relay that's with the fuel pump control module and a brown relay and it turns off OK.
Anybody able to help?
