1996 sun voyager 8352 fuel pump issues

[850morrison]

hello my name is Ryan. I recently got this motor home that was sitting on my grandpas property. he purchased it in 2019 drove it 80 miles and since then it has been sitting. It is a 1996 8352 MGB Sun Voyager by gulf stream. It has 88K Miles on it. I can get it running with starting fluid but not on its own. I removed 20 gallons of bad fuel out of it and put in 10 gallons of 93 octane along with 104 octane booster. I dont have any pressure at the schrader valve on the right side fuel rail with key to on position. I need help locating the fuse and relay location for fuel pump and also the wiring diagram. Also after verifying of the easier items are ruled out what is the best way to replace the fuel pump? I assume i have to drop the tank to get access to it. I appreciate any and all feed back. This is a project that i am finally getting time to dig into.

I can't help with a wiring diagram, you might be out of luck there. I'd start with a wiring diagram for the chassis, Ford, GM, workhorse? the locations can be different depending on where the body builder decided to stretch the harness to, but the components should be similar, and the locations in the fuse panels should be a good enough guide.


Higher octane is not better gas for starting an engine. I'd run a tank of regular once it drives, only use high octane if you need it to prevent pinging.
