Turned her off an tried starting her again. Turned over very fast like no resistance on engine.i have no high oil pressure psi...trying to figure out what let loose after I put my foot in it...

How did the Stand pipes Look and the Dummy Plug ? I Just did 8 Injectors but had to get the Updates standpipes cause the Orings looked terrible . Just a thought

[cajunpsd]

We didnt change them. I had to leave for work and a mechanic buddy changed injectors. I wasn't thinking and didnt order the updated items. My bad.will see where pressure loss is tomorrow afternoon..

We did leak test. Air coming thru oil filler tube...Ipr energized and screen was very clean..so that is good and ruled out..took rail off and inspected dummy plugs and stand pipe.. Orings look good..so far I don't see any problems.. We have not pulled each newly rebuilt injector yet. Is there an oring that seals each injector to the cone on bottom of rail? Thanks, Todd

yes.. And there are also copper washers that seal the injector to the injector cups in the head... Make sure you didn't "leave" the old copper washer(s) in the cups when replacing the injectors. also the oil rail that goes on top the injectors- you want to "press" the oil rail into the injectors(you might have to give a good hit to it in order for it to go in the injectors)- basically make sure oil rail is flush with the head where the torx bolts go into, once they are you can tighten the oil rail down... Just a thought to your no start- this was my problem when i first learned to change my injectors and made a mistake with this. I didnt see that he torqued everything down to specs? did he do the correct procedure for injectors and oil rails?
