Question MY STROKE WON'T CRANK after injector oring change. Help

I have a 96 F250 7.3L and i recently changed all the orings on all of my injectors because they told me that was causeing it to smoke blue at a idle and some loss of power. I did everything as instructed and put everything back together. I am not a mechanic but know my fair share and learn by experimenting. I got everything back on and went to crank it and it just turns over but doesn't fire. It will crank on starting fluid and kill as soon as it runs out of fluid. Any ideas? I took out all the injectors, changed the orings, purged the cylinders, soaked injectors in oil, put them back in, torqued to specs, replugged all glow plugs and injectors, plugged in both gaskets. replaced valve covers, changed oil and filter, and here i am.

Mine did this too. Its like it wont even budge almost like its locked. Hopefully its not I know this is a big concern when oil or fuel gets leaked into the cylinders but it sounds like you took all the precautions. Just keep cranking you may need to hook up another running truck with jumber cables cause that much cranking and your battery will probably drain. But keep going after awhile maybe a long while she will run again.

I agree. There is air in the high pressure oil system. You need to keep cranking until it fires.

I agree, keep cranking, let sit a few minutes and try again. Will eventually run but like crap, will be blowing smoke, drive 15 miles and all should be fine. The oil from removing the injector dropped a lot of oil into the heads.

Fill the HPO rails with oil top up the HPOP res. hook up a jumper box or running truck to your batteries crank it over but not for long it is easy to burn up the starter stop and let the starter cool off before cranking again, when I changed mine this is what I did and it started the first crank.
