    Any error codes ? Does the problem started suddenly ?

    What's the boost pressure? What's the fuel pressure at filter head at idle? Please explain injector cutout doesn't do anything. How many hrs on unit? I've seen guys step on the pre cleaner and collapse the lid.. So was the lift pump replaced or hpcr pump or both?

    Be sure to inspect air system for oil, a little in the lines can be a lot in the air to air
