In my '79 F-150 with a 351m, I have a problem with the engine stalling when it gets hot. It will die, and I am stuck for about 45 minutes until it cools off enough to start again. Any suggestions?

 

I had the same problem in my 79 with a 400. My problem was that when I'd stop my truck I couldnt start it untill it cooled. One of those times I happen to have some water and I poured it on the ignition control box b/c It nearly burnt my hand when I touched it. After I cooled it off the truck fired right up. I bought on from AutoZone but eventually ran into the same problem...I bought my next one from Checker an its working great....I kept the old one as a spare...The symptom for my truck was that when I tried to start nothing would happen...

Hopefully this helps...

Been there before too. Go get a new ingition module from the auto parts store. Keep the old one in case of emergency. If your're junk yarding, keep an eye out for a spare. Just makt sure it has the same color gromet for compatability.

If you want a GOOD module find a Ford Motorcraft OEM module. Many parts stores have testing machines for igntion modules. When you mount your module use spacers to hold it 1/4" off the mounting surface. This will allow cooling air to get to the bottom of the module. Cary the parts store module as a spare. I run an OEM module now and I haven't had to change it for years. The parts store modules would run a year at best.

 

I had a similar problem, but it turned out not to be the module. I had a pinhole in the fuel line, back by the tank. I guess it was letting air in, and with the engine warm it was "vapor-locking" somehow. I had to manually shake the fuel line from beginning to end, until my grand-daughter saw the wet spot. Until then, I had changed modules, coils, etc, and as the engine had cooled off, it seemed fine. That is, until it got warm again. Just one more thing to check out.

 

WOW! That took some work to find!

Thanks for the info.
