I have a 1987 Ford ranger. Recently I have a major problem. When the truck get hot..about 30 minutes ...it quits. I pull of the side of the road and it won't start. I am unable to restart it until it cools down. I think something is breaking down due to the heat but don't know where to start looking. After it cools..it starts right up as if nothing has happened..but...30 minutes later....it dies again.

Any ideas????
Thanks

 

Next time it happens, pull a plug wire to see if your getting a spark when you crank the engine. If not my guess would be the TFI module on the side of the distributor or possibly the distributor pick up coil.

Good Luck.

 

Thanks....I'll give it a try.

 

don't forget about the Ford recall on TFI modules. If this is your problem. I have a copy of a reimbursment form for this item, if I can find it. Ignition coils will act like this also when hot, as the previous poster mentioned. These are $20 or less at Autozone for house brand.

 

 

Ignition Module most likely. It will eventually quit altogether. But until then, it will quit when it gets hot. Not sure of the location on a Ranger. But some V-8s its on the distributor, others is located on the drivers side close to the firewall.

You could also have a fuel problem. Try running it with the gas cap off. If this works it could be the fuel tank evaporative system. Also you could have a vapor lock, is you exhaust system broken? Hope this helps you.
