Help getting SC3800 swap troubleshooting (Page 3/3)

I think it's a MAP issue. I noticed on VCM scan that my MAP reading was maxed at 200kPa. I unplugged the MAP and it fired up, albeit with a CEL for the MAP sensor.
it's after dark now so I'll checkout the wiring in the morning, otherwise I'll be getting a new MAP.

Thanks for everyone who helped. I'll update the post with the final result, but I'm 90% there.

Ryan GMTuners is awesome for anyone that didn't already know. He's help this community for decades. I'm sure I'm not the first person he's spent time giving free help to.

Turns out, the MAP sensor 5 volt reference was pinned in the wrong location(C1P10) instead of being spliced in with C2P33

Engine is out and getting a clutch. Plus I'm fixing a few minor issues.

Wow, good job! I've often said it usually boils down to the stupid stuff. Thanks for letting us know.
