Intermittent no crank no start issue, been happening for a while usually I cycle the key a few times or throw the jump box on it and it usually cranks over, haven't been driving much due to a frozen caliper but I have recently replaced all calipers and rotors/pads. Back in March at one point had trouble getting it turned over and had a P0513 incorrect key immobilizer code pop up but haven't seen that since. Recently trying to start im losing all power inside cabin, no lights no locks almost like there's no battery.thought it was ignition switch so I replaced that but still getting same issue, also replaced mega fuse still same cuts off, power comes back in cabin after a few hours or overnight not sure exactly on timeframe. I was able to start the engine after these issues by jumping the negative on battery to the front ground on engine block. So the question is now what grounds control the ignition and power to cabin that I can check. 2013 Tahoe Ssv
