I've got a 2012 3500 crank but no start replaced injectors, fuel control actuator, lift pump, can position sensor still wont start. 12 psi to cp3, not sure to injector rail. Not showing any codes. Now remotes dont work for door locks or remote start.

 

What is it doing when youre trying to start it? Does it turn over? Does it make noise, if so what kind? Include anything ya might think could be helpful for us to help ya out.
