Ignition issue
I've searched and have not seen anything similar to my symptoms, so here we go:
(1991 with a J-SPEC TII swap/ N374 ECU/ NA wiring harness)
No spark from plugs when grounded to body.
I have checked the following:
-Coils (both L and T) have power
-CAS is wired correctly to ecu
-Relays click, so i am assuming they are fine since the coils have power.
-when it was cranking, the volt meter read 0.01v on the ecu output to the leading coil (haven't connected the oscilloscope yet, but will soon to get a better reading)
-coil wires are wired correctly to ecu
What else can I test? What other inputs does the ECU need to see in order to fire the coils?
I have been reading quite a bit that the N374 ECU is trash. Is it possible that I may need a N370?

I failed to also mention that I have the Neutral switch disconnected(I think it connects to tranny somewhere) and also 2 wires that have same connector(barrel style) and are grounds.
I am doubtful, but would these affect it?
