Well I managed to get it running again after things dried up a bit... and the starter promptly died. The starter also happened to be a rebuild I installed last November. (I'll get back to that below)
The cap, rotor, wires, and I believe also plugs are fresh, but during an inspection I noticed a tear in the rubber shielding on a wire, so those are getting replaced in a few days. The distributor was also missing its dust shield and grommet, so those are on the way too.
I got an inductive plug wire tester (the kind that fits over the wires) and tested for spark... got nothing. Not sure if it's just the tool. I pulled the ignition coil and i'm 99% sure it's the original unit. Resistances across primary and secondary coils were out of spec according to clark's garage-- primary was 40 ohms (normal .4-.6) and secondary was 8k (normal 5-7.2k) so I'm replacing THAT too.
Now I know I have a vac leak/ improperly routed vac system (PO had a turbo brake booster check valve... don't have any pics from before the fire to figure out how everything was routed so we went back as close as we could to stock) and that'll be sorted soon too.
What's really worrying me at this point is in the last few days, since I tore down the ignition and put it back, the first few times I turn the key in the morning the starter doesn't even come on, but I can hear the solenoid engage. Then, the first few turns of the motor are really slow or hesitant, and once it gets spinning like it should, it won't start until I give it some gas.
I'll be able to rule out spark and vacuum as possible causes in a few days, but until then, any idea what could be causing that?
cheers
