Hello everyone, I have a 1991 Jeep Wrangler with 4.0 litre engine. I have done alot of modifications to the jeep including cutting it in half behind the front deats and tubing the rear. My problem is that my battery keeps draining when the jeep sits for a day or so. I have found the fuse that is causing the problem and it is labeled in the haynes manual as the Electronic fuel injection fuse. If I pull this fuse then the battery doesnt drain. My question is how do I figure out where the problem is in the Electronic fuel system. The only thing that I have changed there is the fuel pump. I do remember a problem when I first installed the new pump that the fuse kept blowing under the dash. So I grounded the fuel pump directly to the fram and that cured the problem. So if this is the problem, I dont know which wire was originally used for the ground on the fuel pump. Does anyone know how I can figure this out? I checked and I dont have any stray wires left by the fuel pump. I have looked for wiring diagrams and have not found one yet.
