After all and it seems like a ground issue, put a jumping cable from the nagetive to the engine block and then try the chassis, it’ll work, I had a 08 suburban with same issues till it stopped cranking and it was a bad grounding somewhere and I put extra new grounds in different spots and even works better then it ever has

Have a 2010 with intermittent no crank no start have to pull ecm and cables and eeset electronics for 20 mins to start. Also gauges go crazy and drip and stabilitrak and abs come on until it kicks back in. Pull your "info" fuse in your driver fuse cluster. It cuts power to the bs onstar vcim which is causing interference on the high speed lan or can whatever i dont have a scanner. Anyways youll lose remote start which is what started acting up for me and doing . I got no comm to ecm bcm tccm everything. 3 months thru winter everyday having to pull cables and discharge it pissed me off it being onstar module i would never use
