Re: 88 Bronco II no start?
I would check the eec relay and make sure it thumps when trying to start. A bad computer ground is a very common problem. They used to be in the pass side kick panel. Start here as it is the cheapest problem. Haynes manual used to have a one line electrical diagram. Start at the injector check for power at the wiring harness connector. Go all the way back to the relay. Also check for a bad fuse or a burnt fuseable disconnect. They used to be by the starter.
If one is burnt use two wire size smaller wire to make a new one. Newer models have a black electrical box in the engine compartment. Look underneath for burnt wires.
