Thanks Scott. I think I'm dealing with quite a few total separate and/or related issues here due to the time that it sat for 10 years or so. Picking them off little by little it seems. I think clogged injectors are part of the problem likely. It now starts if I floor it while cranking and then even smoothed out enough to idle with no gas pedal but running real rough. So the condition improved once I got it going a bit. Possibly helped out by the injector cleaner I have in the tank.The aux pulley doesn't matter at all on '89-94 other than the rare California model '94's with a cam sensor.
Unless the fuel injectors are stuck open or something I'm not sure what is going on yet without thinking on it... the system is pretty simple being batch fire and waste spark... The CEL can flash codes, there's instructions in the tech library on the EEC IV code area.
It wouldn't hurt to try starting fluid but also check for big vacuum leaks as they matter on the mid '90 up models with MAF sensors.
Dumb thought, on the crank sensor, the belt didn't wad up and break off any of the chunks of the sensor did it or bend up the vanes? There's two rows of vanes on the balancer.
I'm pretty confident the timing is right now, but not convinced that there is not a sensor negatively impacting performance. Crank or cam possibly. Or ICM, or solenoid or something. Gonna go to testing electrics with a meter and light probably, along with checking compression.
But to your thought on crank sensor. No it wasn't wadded up down there or tangled. Was just loosely draped over the cam actually. Not that that means the Crank sensor is good, but it didn't seem to have taken a hit or anything. Thanks for your thought provoking brainstorming though
