No i only have the pocket scanner. yes u can here the injectors clicking, and ya my oil pressure comes up to normal. my buddy said that i prob have air in the fuel lines but i took the cap off the filter next to the oil filter and turned the key on and fuel poured out so i dont think i have air in the lines. the thing i dont get is that the truck fired up and sounded great but then it died out? and no theft lights it just cranks and all the lights on the dash light up as normal.
nah just thought you may have an air lock or the oring got messed up on bottom filter cap. Can you check fuel pressure? Ive had two instances where couldnt get one to start after put back together but started after I took the allen screw out of the top filter housing to check fuel pressure they started up fine, air lock I guess.
double check the 3 connectors of FICM, make sure they are snapped in. turn key on then loosen one of the fuel lines to the head, just enough to see fuel come out, then retighten, that will help it from being air locked.

you have to check ICP actual compared to ICP desired. I doubt you will have 1400 actual when cranking. If IPR is at %85 that tells me the actual ICP is low. these trucks need 500psi from the HPOP to start.
