6.6 won't start without pumping ...

Just replaced injectors, 6.6 won't start without pumping fuel/water separator pump while cranking...check engine light now on after replacing injectors and now it won't run over 2000 rpm...all is reassembled properly, also has new fuel pressure regulator and glow plug sensor...yup, what's next?

no clues? code reader says fuel rail pressure, check engine light won't clear

doa in bedford, pa wouldn't start, interstate tow garage disassembled the fuel/water separator primer pump (button you push to prime) before I got into the shop area ... possible that it is leaking/sucking air?

Need some helpful replies please...
