I have a 2010 mustang GT 4.6L motor that I am trying to get running using the FMS control pack. per the instructions I swapped out my engine harness with a 2007 engine harness. I get the PCM and fuel pump lights on the control pack. when I press the start button the start light comes on on the control pack, but I dont get it to crank. I hear the start relay in the control pack click when I push the start button. I checked and I do not get 12v on the starter signal wire at the starter. if I do the screwdriver jump between the 12v starter and the signal lugs it will crank once or twice. I do not have the heavy red 12v wire from the altenator or the IMRC connector hooked up.
Any ideas what I can test or any troubleshooting steps? Thanks in advance

I built my standalone wire harness and paid to disable the PCM's PATs.

I'm also having problems; my engine runs and shuts off immediately.

It seems that these PCM 4.6 versions aren't very project-friendly.

Please, if you find a solution to your problem, comment here; it might help me too.
