Nb swap. no trigger reading in composite logger

Nb swap. no trigger reading in composite logger
Hello, I have recently swapped my engine from a 1994 to a built 1999 engine, in a 1990 chassis. I had originally swapped the car a few months ago to the 94' engine using the CAS at the rear of the exhaust cam and it worked perfectly. I recently finished assembling my built 99' engine, I am now using the crank position sensor, and cam angle sensor from the nb however I have no spark when cranking now. I have searched through 15+ forum posts and haven't been able to figure it out yet. I noticed using the composite log feature that I only get one or two events then nothing. I will add the composite log from 5-10 seconds of cranking, and the ignition settings used. I don't know what to look for in the composite log I just know mine appear to be much shorter than others, and I'm unaware of which color represents each signal
Important Details:
mslabs ms3 basic 90-93 pnp ecu
99' block. head, Cam angle sensor, and crank sensor
90' chassis, and harness
1.6l coilpacks wired according to flyin miata swap guide
2 days since running on 1994 engine perfectly
Posted is a composite log from cranking the engine for about 5-10 seconds
Crank sensor came from running car but could be bad?
Here are some thing I have tried so far:
Tested continuity and voltage from where the na style CAS was chopped all the way to each connector
tested spark using coil test mode in tuner studio, I have spark on both coil packs
I tried rising edge and falling edge spark settings, both result in no spark output on cranking
bought a new cam position sensor and installed that
double checked I'm using the correct wires from the original CAS to each sensor
I have a 99 trigger wheel, all teeth are intact, the crank sensor was spaced using a credit card
I will link a picture to the diagram I followed in wiring the cam connector.
I used the yellow and blue wire from the 1.6 harness for the signal for the cam sensor, and the white wire for the crank signal
I would appreciate any help at all, if someone could tell me if the composite log looks wrong that would be great!
