(Batch fire) Only cylinder 2 and 3 has spark, but not 1 and 4. How to correct?

no, i was saying spark b should be pin 33--so the MS harness is correct.
All the sparks are driven off the same integrated circuit on the expander, I'd be hard pressed to think Spark A is working, yet Spark B is not.

Spark C and D are dormant if using wasted spark?
If not, and Spark A and C are firing at the same time, maybe I can switch the trigger source to run wasted/batch. But that probably means I'll never be able to run sequential.
Anything on the megasquirt itself to check whether it be software or hardware?

on a 4-cyl, yes.
IIRC it's wired:
A - 2/3
B - 1/4
You're absolutely certain in output test mode you can't get anything when testing spark b? and that spark b goes all the way from the coil trigger (yellow or yellow/brown) back to pin 33?

Both cylinder 2 and 3 fire when I test Spark B OR D in output test
Nothing happens for cylinder 1 and 4 when trying Spark A or C
Continuity is good from the coil plug all the way to the ECU pin for both Ignitor wires: Brown and Brown/yellow

So from what you said earlier, there shouldn't be any reason why Spark A isn't working if Spark B/D are.
So that means it would have no effect if switching to Wasted COP, activated Spark-A/C and Spark-B/D simultaneously, to try to use Spark C as the trigger instead of wiring to A?
I don't understand the logic if that would work, yet Spark A doesn't work independently if they are part of the same integrated circuit.

Spark D is run to one of the unused wires in the modified ignitor, but not actually wired to anything. I wasn't sure of why it did anything when cycling through the output, if it was set to wasted spark. It makes me wonder if this was to allow for a wasted setup to work even if the COPS are wired for sequential...without shifting or pairing wires as we do for the 1.6L
..but again, does not explain why A and C aren't working.
I feel like I'm missing something real stupid in the setup within MS. Patiently waiting for that "eureka" moment once it's all sorted...but I feel in over my head now. Swap and install only took 1 day. Figuring out how to start the car....5 days and counting.

From reading this thread:
Megasquirt MSEXTRA / MS3EFI • D14 "spark A" Not Working- Not Grounding - MS2/Extra v3.0 (View topic)
I know it's MS2, but is this something common that even new daughter boards or expansion boards are sometimes faulty?
