Start, no-start, start, no-start..?

Looking through my '94 FSM and a couple of other 90's era GM FSMs, they all indicate that the ECM will not pulse the injectors unless you have good feedback from the ignition control module and/or reference pulses from the Opti.
What part of Birmingham are you in? It doesn't look like downtown. I am in Huntsville (and it is awful bleeping cold for MAY~!)

OK. I didn't know what the quads controlled. I probably should have read through the whole thread again before posting.

I'm in Pell City which is east of birmingham down I20.
The no pulse reference at the injectors is verifying what I suspected all along, either ECM or Opti, its just narrowing it down to which one....

The ICM was replaced along with the coil, so i'm discounting those.
