I blew a power steering hose , cleaned up the mess replaced the hose, driving down the road, truck revs up to about 3grand and dies the truck will not start. I have replaced the fuel filter, fuel pressure regulator and new batteries still no start , took to dodge dealer cause I had a p2509 my mechanic buddy said computer maybe needed to be flashed , dodge mechanic said computer is good and needed to do a fuel test , lift pump good, injector pump good but I only had 149 psi at rail he checked the fuel pressure relief valve it was bypassing like crazy, he says I needed a new one put new one on fuel pressure at rail is no 500 psi but still no start , now he is testing the injectors.....anyone else been through this any ideas.....

Rail pressure failed to build up for ECM to fire injectors.
Already replaced fuel filter,FCA and PRV.
The only left to replace would be injectors/tube and CP3.
