Electrical problem
1987 Ford Bronco 6 cyl Four Wheel Drive Automatic 126K+ miles
----------------------------------------------------------------
My engine will not start, however, it will run if starter fluid is used; at least until the small amount is used up. It will occasionally start and run for less than 30 seconds after sitting overnight. It was running fine, then overnight it would not start. I have replaced the negative terminal (it was old & worn) and both fuel pump relays. It ran fine for a week or so after each of the relays were replaced, then the no start. As far as I can tell, the fusible links are OK. When I turned the key on today, I tried to check for voltage at the positive terminal of the fuel pump and got nothing. When I removed the fuel pump and jumped it off the battery, it immediately spurted fuel. What else can I check or replace?
