I know you've checked over everything repeatedly, so bear with me cuz I don't know the specifics of your swap. Did you use the 93 dx harness with your 90 bay harness? is everything pinned to the ECU correctly?

[eeseen racing]

dizzy+distributor i thought that was common knowledge

and Primerdrift i used my old 90 harness and switched the 91 si ecu and dizzy inwirin seems all right going to the ecu


maybe one day someone could come and double check but it all looks right

[BigBearWest]

is it a 91 si dizzy?

[eeseen racing]

supposedly yes

[Primer_Drift]

eeseen do you have both harnesses?

[eeseen racing]

um yes i do

[Dj_FL!PSW!TCH]

Did you swap the pins at the ECU?

[eeseen racing]

ya we did swap the pins

Sorry for the dumb post eeSeen, I was in a hurry. I was going to say If you have both harnesses, retest the bay connector to distributor connector on both harnesses, if they are the same pins then that eliminates that. Then move on to engine bay harness to ECU, if the pin out matches your wiring diagram check for any pins in the ecu connector and bay that might not be pushed in all the way.
