I have a 2012 chevy 2500 6.0 4x4 base model extended cab. I drove to gas station and came back home, about 40 minutes later I went to leave and no crank not even a click of a dead battery. So I bought and changed the relays, starter, battery, and the ignition switch. Still nothing. It doesn't have onstar and the theft lights aren't on. And my neutral safety switch is brand new also. Anyone know anything about this. Also I have power at starter and can jump it with screw diver but that doesn't kick out the bendix. Been through everything I can think of for 2 days now.

 

What was done to resolve this?

so I thought it was the computer for transmission also called tcm. But I had it replaced and still nothing. So then I noticed that the fuse box was cracked so I bought a new lower peice where the wires sit and bought a new fuse panel and replaced them.. starts up everytime and also fixed other electrical issues like the lock button and window quit working on passenger side and now everything works and no problems.
