Default MS3 Basic 1.8 Swap No Spark

Hello,

I was wary to post in this section, but I am having trouble diagnosing a spark issue with my MS Labs Basic. I do get spark while in test mode, but not when cranking. I am also getting combustion out of the intake. Engine was running perfectly prior to being pulled and has not been touched since. RPM is synced. I speculate it might be a grounding issue. Any suggestions would be appreciated. I have attached regular and composite logs below.

Thank you for the help.

Details about the car in question:
1993 with BP4W
1.6 MS Labs MS3 Basic
1.6 coils
Wasted spark
Batch fuel

Hello again! I am still at it.

I tracked down my issue causing no spark, due to improper grounds. However, I am still having issues with the car. It will fire, but will immediately die. I attached a composite log and I am getting a strange inverted signal in the log which I believe is killing the car.

Thanks again for looking.
