I'm not geting tired of hearing about it,,,that's what we're here for...
I'd check spark again.
If your still getting spark it would seem igniter and coil are good,,,and probably means distributors cam and crank sensors are good.
The wires at igniter are notorious for cracking...
I left a main wiring connector unplugged and felt like calling the junkyard once. Fatigue and frustration can make you miss stuff, fur sur.
Check the fusable links(wires) with an ohmeter.
Check the big Fuses at battery with ohmeter. The little windows in mine are fuzzy and I don't trust looking thru them.
I'll try to think somemore on this. Tonite my brains pretty fried over my headgasket.
