I borrowed the neighbors truck (grabbed some food for the fam and put a few gallons of gas in the guys ride) and scored two coils, two coil leads, a distributor and an ECU. Tried the easy thing first. Swapped the coil lead. No change. Swapped the coil. BAM! Started up in less than a rotation. Ahh...Now I don't have to sell them all... Thanks to all for the helpful troubleshooting hints. Stuck with no tools, parts, or equipment, I needed some quick thinking and tips. Great group action!
