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.

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.
