Hey Y'all:

Help me if you can. Just bought a sweet '86 F-150 Supercab with just 42K on it. After a week's driving it has started to shut off on me. The engine dies with no warning. Usually I can restart it with no problem. Replaced the fuel filter and ran Drygas thru it because it had been sitting for a few months prior to me buying it. I suspect either the ICM or pickup in the distributor, but I's like some input before I get out my goose hunting license.

Thanks.
Pat

 

Check all the wiring for a loose connection. When it dies does anything else go out at the same time. Radio, fan???

Engine dies, all else normal. It is as if somebody hit a kill switch on the engine. No hesitation, no surge, no warning, engine just quits running. Hit the starter and it usually fires right back up. I can't see any pattern that would indicate a particular set of parameters.

 

my neighbor had the same problem believe it or not with a 86 half ton long bed 302. he replaced the fuel pump and it works fine now. Hopefullly thats all he replaced cause i wouldnt want to mislead you but im pretty sure thats all he did.

 

my neighbor had the same problem believe it or not with a 86 half ton long bed 302. It had been sittting for 6 months and its in great original condition. He replaced the fuel pump and it works fine now. Hopefullly thats all he replaced cause i wouldnt want to mislead you but im pretty sure thats all he did.

 

Wow!! Two neighbors with the same truck type and the same fuel-pump problem!!! What are the odds of THAT?

 

Problem found! The Ignition Control Module was the culprit. After replaceing it the truck fires like a new one and no longer dies on a whim.

I love my truck!
