I have a 1965 coupe and it will not start. I drove it last summer and got to my destination but the engine would not turn off even when I removed the key. It fried the wires in the process. I have replaced the wiring harness, starter, voltage regulator, and the cellinoid. Now it will turn over but not star and will continue to turn over when I remove the key. Does anyone have any suggestions? I am stuck on this.
