All, I have been dealing with my 2014 3500 6.7L WON"T START issue for two years. Turn the key on and nothing, I get out of the truck and either rock the truck or move it sometimes just a few feet in neutral and then it will start. Dealership has had it several times but they can never duplicate the problem. Also has never shown a code. The common denominator in my opinion is when I have to roll the truck forward or backwards to rotate the transmission out of its current position, almost like a neutral safety switch problem? Any help would be appreciated.
