Hi! I am new to the group. I have a 73 400 automatic Roadrunner with air and electric windows, It starts and runs great but when I shut it off, I can't get it started and there is no spark at the coil. It has to sit till it cools off and then it starts. I replaced the coil, the alternator, the plugs and wires and the ballast resister. Where do I go from here?
