I have '86 305 motor (fuel injection)in my '59 half ton pick-up. The motor won't start when hot, but will start again after sitting for 20 minutes or so. Any ideas what the problem might be?
I've already replaced the starter, plugs & wires, & ingition module.

 

Is it cranking and not starting or does it not crank at all?
If it's not cranking until it cools off it's probably starter heat-soak problem.Could also be ignition advance related if it seems to be firing against the starter, this is aggrivated even more by heat.
