I have been have trouble with my truck building enough rail preasure to fire up. It will reach 900 psi and not go any higher. The weird thing is that you can push start it and it will start right up. Once truck is running it will run perfect. Check accual rail preasure with efi when truck is running and I can get it to he 23900 psi at WO.
