Might be worth a shot to blow air thru the injector itself
gotta be kinda spendy to put new injector oring kit on everytime you pull it
or they should be replaced anyway the copper crush washer at the bottom is the one that would concern me
But Im kindA A prefectionist in that regaurd

ok after switching injectors around abit and doing air tests, it sounds like the injector that is now in position #1 may still be leaking. (not the one I already fixed)
I'm going to put everything back together. Run it and see what happens. if it still has a no warm start issue I know exactly which injector is the culprit.

Could it be a problem with the oil rail itself
I think odds are slime that 2 diffrnt injectors in the same spot would have a problem
If you have a scangauge you could see if its got a HPO leak once its back together

If 2 injectors in the same spot and it still hd a leak I dont think its an injector leaking the air that would mean both injectors were bad thats highly unlikly
wonder if its the HPO rail or something
anyway it should run alot better since you replaced that oring in the top of the injector that had blown out
I bet it was gushing oil right there when it was blown out that injector looked pretty oil soaked

BLADE thanks for the suggestion.
OK so I pulled the injector that I thought was bad and put the air nozzle in the top. Air leaks out of the two smaller holes that are on top of the injector.
Pulled the injector next to it and tried the same test. No air leaking out of the top.
Is this something that I can fix? Do I just need another HPO seal in the injector?

I smooth missed that post. I really need to retake that Evelyn Woodhead sped reeding test 'n see iffn I rilly passed 
Steve....there's really not that much to the top part of an injector (spool valve section). You can remove the small bolt that holds the coils together and the spool valve will slide out. Take lots of pictures so you know how the wiring, shims, and coils go back together. The valve is directional. You can also remove the two torx bits that hold the spool valve body to the injector body and it will come off but it's directional in relation to the body also. There is a small o-ring on the bottom of the spool valve body that might be broken.
This is the best cutaway picture I could find of the spool valve body but it doesn't clearly show the oil path and/or why it might be leaking out the top: Page 43: Fuel Management System It almost sounds like the spool valve is "hung" open but it only moves .017".
I'm also adding a comparison link which might help: https://www.powerstrokediesel.com/do...Comparison.pdf

Ok after a few mishaps it is back together. Tried to start it>>won't turn over at all.
Seems like the batteries are wearing down so I will recharge them.
Getting codes P0603 and p2623
Is it usually hard to restart, especially after I pumped so much air through the system?

Yes it will take a few to start its gotta get all that air out
mine took probably 2-3 min of crank thats not including rest periods
P0603 just from batts unhooked
P2623 Injector Control Pressure Regulator / Open
this last code is why it wont start is it fulley plugged in the IPR

when you were energizing with 12 volts to the IPR for the air tests Did you keep it short periods of time
the IPR can burn up if energized to long with 12 volts
do you have a scangauge
or anything to watch HPO
