I have the same problem but I can jump start my truck through the starter. The problem started with my vecu back two weeks ago I had a blown fuse for air suspension and def lock so I went took out the fuse I didn’t had matching 15a fuse so I put 20a then oh boy some nasty smoke came out of my vecu and ya i fried my vecu still don’t know what cause that but I went out got the vecu from same truck as mine and everything worked fine just have check engine light on all the time but no problem running the truck I know I had to go to dealer to clear all the codes and have them put my Chasee number a
