Ok guys here’s my issue, driving the bronco today and she died on me. turned the key and got a battery light, my abs light, no check engine light and fuel pump wouldn’t prime. Let it sit for a minutes and boom it came on, surged and sputtered then died. Tried again about 5 minutes later and it fired right up (keep in mind when the pump would prime the ce light would come on when the key was in run) . So I get home and start testing, I swapped the relay, checked grounds, reset inertia switch just in case etc...nothing. So I cleaned my garage come back out and it fires right up again.
I’ve had this problem in the past and it came down to a broken wire in the obd1 access plug. I have 2 questions, can I “jump” the FP to test it and make sure it’s not just busted, and 2 what are your thoughts on the check engine light coming on like normal when the FP primes but other times when it won’t prime I get no light at all. Truck still cranks regardless.
The biggest thing is that I got it home, but ide like to figure this out. I’m not an expert with an multimeter but with a little guidance on which wires to test/jump etc I should be able to work thought the FP circuit (89 Bii)
