(Batch fire) Only cylinder 2 and 3 has spark, but not 1 and 4. How to correct?
See post #15
Cylinder 2 and 3 are firing together whenever Spark B or D is selected in the output test mode
Cylinder 1 and 4 are dead silent whenever trying A and C
Continuity checks out on the COPS harness. I switched the coils around and the coils themselves all work.
So what would prohibit A and C from firing? anyone have any ideas? I don't know how to proceed with this short of testing continuity back to the ecu plugs, then beyond that...is there any other setting within Tuner Studio that I'm just missing or is this a hardware issue?
I'm seriously at a loss and don't know what to do. Braineack gave some advice to help get the fuel pump priming which is awesome, but I still have no crank signal, spark or fuel. TPS works fine, crank sensor gets voltage. I checked the continuity of my COPS harness and it seems to be fine, but nothing fires when plugs are grounded. I believe that since there is no crank signal, MS3 doesn't know when to fire or inject fuel.
I tried plugging in MSPNP1 and was able to pull a composite log of the trigger wheel, but MS3 is a complete blank.
BP4W motor and sensors (Ditched CAS)
SuperMiata 36-1 trigger wheel (tooth one is ~180° from top when crank is TDC) so about 60-65° offset from crank sensor at TDC
sequential capable but tying to run batch for now
Borg Warner EFR6258 Turbo
Innovate MTX-L Wideband O2
Using BP4W throttle body/TPS and IACV
Am I missing something? I feel like my best chance of getting this to run is reverting back to MSPNP1

There is no signal to the MS3. I cracked the unit open last night after reading on the forums, but couldn't find it; or i was just at the point of throwing my hands up in the air. I will try again once Leach0789 gets back home.
I was hoping to run batch just to get it out of his garage. Then I can wire in the inj/spark c and d and take a composite log of the crank and cam signals to see if a code could be generated to support the 36-1 trigger wheel and stock 99-00 cam gear. But for the time being, just batch on the trigger wheel is the goal.
Spark A runs to the top connector on MS3. Top row, pin 14. If viewed from behind, 6th from the left.
edit: I'll check for spark b location in a moment
firing order is 1-3-4-2 iirc
I haven't wired it sequentially yet since there is yet a code to run the stock NB cam position pulses with a 36-1 trigger wheel. Just trying to get it to run on wasted/batch spark and injection for now which should just alternate between SparkA and SparkB. The trigger for the coils are paired on the COPS harness per the 1.6L instructions
