Ok here's what the bronco's doing and what I've done. Wife was driving it and it died. Got it towed back home and she tried to start it back up. Starter cranked over but the engine didn't fire. I was out at sea when this happened. The ground wire ended up melting so she replaced that. I got back and went to work on it. I tried to get it to start but I wouldn't even crank the starter over. Turning the key wouldn't turn the starter over(not even a click) but if I jumpered across the starter relay with the key in the run position the starter would crank but the engine wouldn't fire. None of the acessories i.e. headlights, radio, rear window, door locks, door windows will work but the hazards do. I replaced the starter relay and ignition switch and still got nothing. If anyone has an idea I'll try it. Thanks.
