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!
