Default Yet another MS3 + VVT in a 1990 that won't start

Threw the ECU in yesterday, finally filled it with fluids and having issues getting the thing started. Took a log of cranking which is pictured below. Is my cam signal inverted? Looks like I am getting sync, however.



Log & MSQ attached as well, although it should be relatively boring as it is just a MS3 basemap with sequential injection enabled.

Thanks!!

edit: my spark settings are currently "falling edge" & "going high", which jives with the logs?

Should be rising edge, unless it should be falling...

Basic MS3s with a board version V3.2 or higher (such as this particular unit) use falling edge for the 99-05 and rising edge for the 90-97 (CAS).

Hmm, so if you guys think the log is good and I am getting sync, should I move on to checking spark&fuel?

Thanks so much everyone! And thank you Dimitris, for dealing with my barrage of emails earlier.
