As for the coil I do believe we are running the correct one, not sure if there is a different one but am going to check tonight. We have tried replacing the ICM, the Voltage regulator, the Starter Solinoid(a few times), the starter(a couple times), the alternator, the distributor, cap and rotor. The distributor rotor sometimes gets so hot that it could possibly burn someone. We've also replaced the spark plugs. The coil continues to get extremely hot.
As for the vapor locking, the reason we believe it is vapor locking is that when the engine would get extremely hot before we did a radiator flush, the truck would shut off and there would hardly be any fuel in the visible fuel filter bowl between the mechanical fuel pump and the carburator. Thus causing no fuel to the carb.
Up until time of our purchase of the vehicle, we are not 100% on how much changing the truck has endured. All I know is that we have had to work on it quite a bit this past summer and it has almost cost us more than we paid for the truck.
I am getting very fed up with it stalling on me at the worst possible moments, for example while driving down a very busy street in our town. Its at the point where I don't take it out on the highway like I would like to be able to do. I need this truck as a general means of transportation. If you can help in any way shape or form it would be more than greatly appreciated.
Thank you so very much.
