Exclamation Ran fine, No rpm signal MS3x

I am having issue with Megasquirt getting RPM signal. I had the car running a week ago when I came back out to mess with the car I am getting crank but no start. I am very new with MS3 and electronics in general. I am seeing in many areas about adjusting the pots. I had originally had it running on 7.5 turns clockwise. I have tried reflashing the firmware. I had forgotten to unplug the ignitor so I am not sure if I killed it or not. Im kind of at a loss as to what could have changed. Maybe bad CAS?

1990 1.6
640FF injectors
MS3x - following trubokitty build

I have attached a composite log, a datalog when the car was running, and the tune it was running on (running rich).
I am getting nothing on the tooth logger.

I may get a JimStim to test the board.

If there is any more information that will help diagnose, please let me know.

Got the voltage at top of R54 to 2.25V and am getting an RPM signal now. 8.5 turns clockwise.
