I recently installed new 180/80 injectors from a small one man shop he has a good reputation I put them in and it had a bad seal so it miss fires and had a lot of white smoke so I pull them and put new seals on them reinstalled them and now it will not fire. I have been cranking for over 2 days only builds like 45 psi that's what the icp sensor says. I have the batteries on chargers they have plenty if charge it will not fire I don't know what to do it ran before I pull the injectors I just don't know there's a intermittent cam sensor code but the tach works I have ordered ipr seals and will install them after anyone have any idea what's happenening?

 

Should of stayed with a well known shop that does injectors such as Jim at Rosewood
As for your original question you have either air in the system or have a massive hpo leak, either from the injector O rings or, hpo rail drain plugs

 

I never pulled the plugs on the rails and the truck ran before I pulled the injectors also my ipr is at a 55% duty cycle when turning over the engine

 

Check for uvc connections,possibly a bown fuse #19 I believe.

 

All the fuses are good lIke I said thought I had a bad orings so I replaced them all now it won't fire at all

 

By any chance you have your valve covers off? If so re check the connections and that the injector solenoids are nice and tight. But sounds like the injectors weren't done right, since you had problems from the beginning of the install, might want to take it as a possibility

 

Normally you pull an oil galley plug on each side, then crank until you get oil. It bleeds the air out of the system. I am concerned about the injector build. Hopefully it works out for you. Good luck

 

If it's only showing 45psi icp while cranking then you have a major hpo leak or no feed. I know it sounds like a dumb question but how much oil is in the truck? Did you check the hpop reservoir? And are you sure. If those two and check out and the ipr oring don't help I would recommend pulling the valve covers off and watch for oil escaping while cranking.
