I currently have a 1987 R10 dual fuel tank truck. The drivers side fuel tank was disconnected prior to my ownership due to it rusting out. It’s my understanding the truck stopped running while the last owner was driving and he was told it’s the fuel pump. I checked the fuel pump by directly connecting it to a 12 volt battery and it runs fine. The truck will turn over but not run unless fuel is squirted into the EFI while cranking at which time it will run. A friend used jumper wires from the male plug on the drivers side wiring harness coming back along the frame rail to the male fuel pump plug on the passenger side fuel tank and with me in the cab it started. He told me to get a 2 wire female plug to connect to drivers side male plug and wire it with another 2 wire female plug to the passenger fuel pump and it should start. Not sure if I have the plug wires connected to the correct connector plugs or maybe they go elsewhere. There are only 2 other female plugs on the drivers side wiring harness where this other male plug is located. I’m trying to make contact with my friend again but know he is extremely busy and really hasn’t had time to help me out. Hopefully someone on here has had a similar issue or is more knowledgeable with automotive electrical than me.
