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?

Most definitely.

I had the fuel supply and return backwards. I also forgot to ground the coil packs. Car started right up just in time for the event on Sunday!!

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