LY6/6L80 swap no start

[einarak]

I´m having trouble with a 2008 LY6 swap, E38 controller, after market wiring.
I get no spark, and no injector pulse.
Could it be because of a broken cam sensor? At first when the wiring was installed, the connectors for the maf and cam sensor where swapped. Is it possible that it could have killed the cam sensor? When cranking "Cam sensor counts" stays at 0, should´n I be getting some movement there?
Also the oil pressure sensor seems to be bad, it shows 24kpa (3.5psi) at all times, is that maybe the problem, is it possible that the ecm wont allow a startup since it sees no oil pressure?

The only codes Im getting are the regular ECM-TCM not friends codes...

[] P0700 - Transmission Control System (MIL Request) (Pending) (History) (Current) (Immature)
[] U0100 - Lost Communication With ECM/PCM A (SES) (Pending) (History) (Current) (Immature)
[] U0121 - Lost Communication With Anti-Lock Brake System (ABS) Control Module (Pending) (Old) (History) (Current) (Immature)
[] U0140 - Lost Communication With Body Control Module (Pending) (Old) (History) (Current) (Immature)
[] P0700 - Transmission Control System (MIL Request)
[] U0100 - Lost Communication With ECM/PCM A

att is a small log with short cranking (the only log I remembered to save )

Who's harness? Did the motor and transmission comre from the same vehicle or same year? Did you disable VATS? Double check all of your grounds and connections. Make sure your computer/injectors are receiving power while you are cranking and not with just the key on.

psi conversions harness, motor is 2008 but I think the trans is 2009 (at least its older than 2010 that is for sure). Both Vats been disabled, starter check and starter diagn disabled, all grounds good, and ecu getting power at key on/start, I checked that specially.

Did you do a write all for the vats, starter, and diagn? Also, I think you have a ECM/TCM mismatched. I believe GM changed some stuff in 2009 with respect to the ECM/TCM.

New cam sensor was innstalled and it fired up right away. So it is confirmed that swapping connections on maf and cam sensor is deadly for the cam sensor. The ecm and tcm was sent to psi to have them matched, but im goint to put a 120 ohm resistor on the bus out on the tcm to se if it fixes the connection error. Thanks for your help
