basically replaced both rocker cover gaskets as leaking oil and now wont fire up!

i had all injectors out so fuel system will be empty which i think is the problem.
the valve ontop of the engine from the tank only bleeds fuel upto the high pressure pump but looks like theres no way of bleeding air from injectors and fuel rail?

fault codes reads fuel rail pressure sensor performance which im sure is because its not seeing the fuel pressure as sytems full of air?

any help much appreciated

I would have expected the high pressure pump to just expel the air by that point, I assume the injectors went back in the same positions? Have you pulled one out again, put it in a container (if you can) and turned it over to see if you get any mist? ( got to be real careful if you do that) 2012 5.0 SC AB
