Hey guys
Have an issue with my 79 and can not figure it out.
Three times now in the past month I have been driving down the road and my motor cuts off. No power steering, but the radio and head lights still work. There isn’t a funny noise or weird action from the engine before it does this. It will not restart. I have twice left it for 30 minutes and came back and it would turn over and run for a short amount of time. When I had it towed last time they replaced the distributor thinking that was the issue.
They checked the fuel line and it was clear with nothing in the filter.
I can’t keep paying for towing every time I drive it.

Anyone ever had an issue like this??

Sounds like an ignition control module.

Ditto on control module, or even coil will do that. Heat related is hard to troubleshoot.

Honestly you can carry a gallon of water and dump it over the module to cool it down and see if it restarts. That is one way to trouble shoot it.

I repair electronics, while water WILL cool a TFI down, a better recourse is to get some electronic FREEZE spray, or even Computer CANNED air to cleanem with, Its either fuel, air, or spark.... Hope ya nail it.. 87 Bronco II owner..

Ignition Control Modules (ICM) and distributor Ignition Pickup Coils fail with heat like that.

Your Pickup Coil has been replaced. It's inside distributor.

If you replace ICM and it fixes it, replace the coil too. Ford trains all their techs to do that automatically because an internally shorted coil will run just fine, but the added current (heat) it places on the ICM circuits cooks them prematurely.

These guys got right! Whoohoo this gang is awesome! Hope he swapped em out. Should run fine when he does

Hey did you replace the control module. Did it make a difference.

Hey did you replace the control module. Did it make a difference.

Another little wire can alo be over looked. Its the yellow and black wire on the solenoid side of the battery area. Happened to me the other day--in case its not the module box.

Lots of folks have fell victim to the old brain box..

I agree, the old duraspark modules were problematic at best, (I used to carry a spare in the glovebox just in case)
I actually gutted a duraspark module and mounted a GM HEI module inside. Some relatively simple wiring mods and lose the resistor wire and that's it. Hei has variable dwell control so it runs noticeably better and you can run a more modern E-core coil without frying the module. Still looks factory then too!
Hope that helps
Cheers
