O.K.. I don't know if this fixed the problem but just for trouble shooting purposes, I ran to AutoZone and picked up an ignition switch for 67 GM cars that had the same switch positions and the pins on the bottom were in roughly the same spot.. I had to grab one of the terminals and rotate it 90 degrees, but with a little tweaking, they all lined up and reluctantly complied with being jammed into the factory plug. Now.. the starter works like it is supposed to and I haven't had any issues, but that's how the other 3 ignition switches started out. I'll keep you posted!.. Something I did notice though, When you put your key in the ignition and turn the key to "on", can you hear a switch or relay power up under the hood? I can... Don't know if that's normal, but it does it with every switch I have tried.
The corvette works on a slick RFID system.. the key fob stays in your pocket and when you get close to the car it lets you open the doors and allows you to start the car with the button.. I miss that setup, since I sold that vette, I have walked away from my truck several times and left it unlocked.. they sell an aftermarket setup for about $550.
