Thank you sir. I will look in to this.

I have a 2000 3500 5 speed. New built engine. Currently getting about 9 volts to fuel relay. Truck started and ran upon engine install but oil change place arced alternator on oil filter. Injector pump was fried, so I replaced. Traced back to computer. Sent off twice and got same result. Installed computer on another truck, same result, have to jump pins for relay to start engine. Sent off to Auto computer specialist this time, same result. Fass comes on and works fine but injector pump won't create pressure while this relay is getting low voltage. Please help. I have used this site for testing wires and can only come up with computer failure but after repairing 3 times now with two companies, I'm at a loss.
