I have a 1990 bronco that I was wrecked when I bought it. It ran fine but when I was replacing passenger side fender, I forgot to disable battery and the hood support arced off the starter selinoid. Didnt think anything of it until I tried to start truck. It cranks and cranks but wont start. I replaced the starter relay, ignition control module, coil, pick-up in the distributor. Still nothing! My new guess is it is a fusable link somewhere in the start circut.I also ran diagnosis test and got no codes! Please help, thanks

Double check the fusible links

Check for battery voltage at the coil not there could be the ignition circuit is open or the ignition switch has an internal defects.

Try this take a wire from the battery positive straight to the coil positive-and attempt to start.

I have power at coil but no spark. Tried new coil, ignition switch, starter relay, icm control module, pick up coil in distributor. Tried to check fuseable links but not sure I checked them all. There are a few by the starter relay, checked those and they seem ok. Are there any more elsewhere? Also when key is on check engine light is lit and so is engine light, when I try to start both lights go out and when key returns to on position and vehicle doesnt start there is a click and both lights come back on?Any help would be appreciated. Thanks

For no spark

Disconnect the coil wire from the distributor ground it and crank engine over -if it spark and nothing at the wire end on the sparkplug-its coming from either the rotor or the cap.

Also inspect and test the EEC Power relay
