Electrical problem
1987 Ford Bronco V8 Four Wheel Drive Automatic 200.00 miles

When I turn the ignition switch to the "start" position, the truck will start. But when I release the switch and it returns to the "power on" position the truck dies. I first noticed this when the radio and the elect. Windows would not operate unless I keep a foward motion on the key switch. Not to the "start" position but to the "power on" position. I have removed the steering wheel, replaced the key switch, cleaned and lubricated all mechanical parts and cleaned all electricial contacts. My grandson is giving me a fit about not takeing him fishing, so please help me exorcise this demon.

Hello,

Sounds like your fusible links up by the starter solenoid have gone bad just tug on them to see if one is rubbery. Here is the location also check by the starter solenoid.

Check for power at the ignition switch and through the fusible links

Check out the diagrams (Below)

Please let us know what you find.

Cheers

Bronco won't stay started. When I turn the key to the start position, it stays on. Once I release it to the run position, it shuts off. Since the issue I have changed the battery, the solenoid, resistor, ignition switch, the starter, and the ignition cylinder (where the key goes). I am at a loss here. Would it be easier to just replace the distributor, distributor cap, and module instead of pulling it all apart like that? My mechanical skills are limited.

Please help.
Thank you,
Rick

If you loosen the distributor and turn it towards you, you will not have to remove it. Just make sure you mark where it was for the timing.
