Cleaned up all the grounds I could find under the hood and bypassed the ground with jumper cables and still nothing. Tomorrow I’m taking the intake back off to make sure I haven’t pinched something.

Had 2 friends help me look for a ground problem and nothing so today went to a wrecking yard and got a used bcm. Fired right up but now my air bag light is on and a new engine code popped up, crankshaft variation not learned

Just for kicks, I’d put your other BCM back in and see what happens.
that's wild.. I would love to know what killed the bcm.
the new one probably needs flashed to the car. few different ways to do it.

My thinking is it was bad before I ever started working on it. Was just waiting for no voltage to finally let go. I haven’t had any weird symptoms from it before but I definitely didn’t short anything while taking the negative off and back on. I’ve seen a couple vids of the same symptom but no cause.
And way to do it besides a dealer?

TBH I’m kinda curious myself. I don’t think it’ll fix the no start but I wonder if the airbag and extra faults I didn’t have before go away. Oh and my radio says locked and automatic lights no longer work but that’s programming most likely.
you could program it yourself with techline connect/sps but you need a windows 10 pc/laptop and a mdi2, a mdi2 clone runs around $200 or so, maybe a little more. The programming fee is $45 for 2 years of programming. only for 1 vin.
