Hi Blitzkreig75,

I hate those kind of problems, don't you? I have a couple of ideas that you might try.
You didn't say if you had checked the grounds. They are just as important as the hot leads. Take the ground cable loose at the engine block and clean the connection and the block post. If you use sand paper, be sure to clean the residue off after sanding. Make sure the starter is bolted down tight. It uses that connection for its ground, along with the ground cable on the block.

Measure the voltage on the wire from the ignition switch to the starter solenoid. It would be nice to know if there was a difference when it worked and when it didn't. Might be a bad ignition switch or a bad connection from the fuse panel to the ignition switch. Here's an easy test for you. Connect a wire to the solenoid terminal and bring it up near the battery. When it won't start with the ignition, see if it will if you touch the wire to the positive battery terminal. That should tell you right quick if the problem was with the 12 volt source from the ignition switch.

Let us know what you find.

Very best regards,
