grounds

x2 on the bad ground cable.
If your ground cable has an additional smaller #10 wire that connects from the battery to the chassis that wire will attempt to carry the power through the chassis and ground strap on the engine. That could be causing the wacky stuff you are seeing.
Also, check the ground straps from the body to the frame.

As stated eariler your main ground cable should go directly from the neg battery post to the engine block, if it isn't you need to fix it so that it is. There should be a smaller wire 8 to 10 gauge, that goes from the neg post to the fender, two woven bare straps that go from the intake manifold to the rear fire wall, and a 8-10 gauge wire that goes from the passenger fender, by the heater box, to the frame.

it sounds like you have the posts on your starter crossed up some how. The pos battery cable should hook directly to the large stud on the starter solenoid, and a bare woven strap goes from the other stud on the solenoid to the starter motor....... that woven strap is not a ground, it is what supplies the voltage to the starter motor when the solenoid engages.

the two smaller wire...... the purple wire goes to the "S" terminal and supplies the solenoid pwr to engage etc..... The other wire Yell or off wht, goes to the pos post on the coil and provides a full 12 volts to the coil to aid in starting

If you reverse the two smaller wires when you turn the key to start you are sending a full 12 volts to the coil and nothing to engage the starter, since the other side of the coil is connected to a ground, after the windings get a full charge and the dizzy isn't spinning because the car won't start, there isn't anywhere for the coil to dump etc...... and could cause wierd things to happen etc.....

verify that you have the wires routed correctly.

First of all I want to thank everyone for their help. It finally started the ground wire was the issue after looking at carefully it was melted right at the connection. It also cause the neutral switch to go bad. I ran a new ground wire and bypass the neutral switch and it started right up. Thanks again to everyone
