I have a 91 bronco with the 5.0 efi with terrible electrical problems , so many that it must be something simple , I'm simple, but after chasing power, grounds, relays , still nothing. Please help.

Sounds like it could be a bad fender mounted solenoid.

Battery cable goes to one stud. The other big stud goes to the starter.

The little stud comes from the ignition switch.

Probably start there. You can jumper across the two big terminals with a screw driver or pliers or something to see it will turn over.

Do you have a wiring diagram?

Didn't think the ECM had anything to do with cranking.

Neutral safety switch?
