2013 no crank.

I would split the under hood fusebox and check for corrosion and as mentioned check those battery cables. K.I.S.S.

I wish that was the problem. I’ve removed and cleaned every ground, checked all the wires in the harness, I’m still having issues. I’m going to try and get a local guy with the big boy scanner to come see what he can find. I can’t remember what it’s called but he pays a lot of money to GM for licensing. Scans everything? Hope he can point me in a direction.

You can buy a tech2 clone for ~$400.
He might be using a newer scanner, but the tech2 will do everything available for our trucks.. in case you get more issues in the future..

Good luck and keep us posted!

Update if anyone is concerned. The wiring harness connector, the one that exits the front on the fuse box, had broken tabs that hold it to the fuse box. I hope I can find just the plastic connector and swap that.

mine was sort of like that, the xmas tree's that hold the harness up under the bottom of the fuse box were broken so I drilled holes in the splash guard and zip tied in place to keep them from pulling under the bottom of the fuse box.
gm only sells new harness blocks so all the wires would need to be de-pined and moved to new connectors
