I seem to have potentially fixed this issue. I'll know more when i can run it for about 30 min and let it sit for about 10 and try to start it again. (Replicate the original problem). But here's what I did.
Troubleshooting. Jacked the car up, looked at the wiring at the starter. There was the WHITE wire... Wasn't sure where it went. Touched it... it sparked. Hmmmm.... Turns out when the previous owner relocated the battery, he ran a WHITE 10g wire from the starter to the horn relay bus bar. But the way he did this, was the ran a white wire CLEAR around the entire engine bay, around the drivers side, around the radiator and to the original red wire that used to run presumably from the battery. Anyway, that original red wire ran to the horn relay. SO.... why did it spark? Turns out the wire was WEDGED between the header (wrapped in heat wrap) and solenoid. The wire had been burnt pretty good, and looked corroded and was sparking/grounding out on the solenoid. Next.... the Exciter wire (purple ignition wire???) was also burnt to hell and previous owner put electrical tape over it. Tore the tape off... .the wire was shredded. I'm not even sure how it got voltage through the wire.
So..... replaced all these wires, wrapped wires in heat shielding, routed them further away from the headers and WHALA!... Started right up. Amazing.
Is this the solution???? like i said... find out when i can take it for a long spin.
But after reading your reply Dave... I also noticed the solenoid is VERY close if not almost touching the heat wrap around the header. Whomever replaced this header bought a high performance one. I think it was called a Proform???? I forget and I'm not in the mood to crawl back under the car. I took a shower and I'm drinking a rum and coke.
Regardless... I love this forum, you all are incredible. I'm hoping the wires were the problem.
