I have a 1986 350 Corvette. It dies and an hour later it will start. Not this time. I had it towed home and the next morning it still didn't start. I jumped a wire with a light to see if it was getting fire from the spark plug wire to the plug. No fire. It seems to do this after it is warmed up.At least six miles out of town.When I put the wire on the dist post to the light it got fire and started. Wow. I had the ingnation mod. checked and it was fine. Could it be the chip in the key? Does anyone know how to jump around that? Any suggestions would help.
