Apparently, at times when trying to crank, I am not getting fire. At first I thought it was a carb problem, but the last time it happened, I checked and was not getting fire thru the plug wires. This problem seems to be worst when I've run the car for awhile and it's hot. Evenso, it will do it when cold as well. I have an HEI dist and replaced the coil, cap, and rotor and still have this problem. If anyone has a wiring diagram I would appreciate it. Also any suggestions as to what may be causing this and how I can figure out, I'll thank you in advance.
