Bob Devol's Profile
Bob Devol's WebsiteJust in case the fuel rail fittings are corroded shut (not uncommon), you can also make up a fuel drain hose that can be hose clamped to the fuel filter outlet side and dropped into the gas can.
To activate the pump on a GEN2 without a separate pump switch, use a small piece of safety wire (or any un-insulated .032 wire) to make small shunt that can jump between the two fuel pump relay plug female sides that complete the fuel pump circuit.

It can be done w/o messing with the relay using the diagnostic port. Don't have the info here with me, maybe someone else does? Dave Harriman

Posted: Sat Aug 13, 2016 2:27 pm I thought it was from Mike Davies on fuel pump testing. One of the wires from the 4 or 5 pin connector for computer code reading that is by ECU. Grounded out one of those wires and fuel pump would run.

Posted: Sun Aug 14, 2016 10:20 am You can also run a wire from the positive lead on the fuel pump up to an insulated quick connect near the master switch. I then kept a one foot piece of wire in my tool box (with a mating insulated quick connect on one end and an alligator clip on the other end) which I would hook up to the master switch to run the fuel pump.

Posted: Sun Aug 14, 2016 3:33 pm IIRC, the grey with pink wire is the ground, jumper that one with the one next to it, on the end of the plug(black?).

Posted: Sun Aug 14, 2016 10:12 pm That sounds very familiar Dave. Can someone confirm those two wires?
