Bulla I believe that hole that was filling up is the vent line for the HPOP and will be sealed off by the gasket at that point not open untill the very top of the resivour, someone please correct me if I'm wrong!

Here is a link to HPOP diagnostics... and this remark in another forum (emphasis mine)

Well when I removed it I think that a little ball bearing that is brass fell out into the ipr area. When I removed my ipr there was this ball bearing sitting inside the pump. So I don't know if the ball bearing goes into the end of the ipr or back at the end of the plug with the rod. I hope someone knows what I'm talking about.
Look through the IPR hole you will see a little hole machined out for it, the rod goes in from the bottom so it will not fall out of that hole...it blocks the bleed hole on the front of the pump kind of a check ball if you will.....
drop it through the ipr side into that hole, insert rod from bottom, then plug...then install IPR....clear as mud?
On edit good thing you saw that truck wont make pressure without it, would be scratching your head why the truck dont start after reinstall...lol

Do you have well charged batteries at this point? DO you get any smoke from exhaust (when trying to start)? The PCM will not command injectors unless it sees adequate voltage...I believe the magic number is 10.5 VDC while cranking. Throw a charger on it and make sure the batteries are fully charged.

The batteries were low but we charged them for an hour while putting things back together and then when we went to start it we put the charger on Boost. Yes there is smoke... whitish color smells like its trying to fire but just won't.
Also we pulled the ICP out again and oil shot out pretty good... a lot better than friday, friday it just slowly bubbled out and now it comes out fast.

we did fill the HPOP up before trying to start... I have gave up on it for today to research a little more. But that was also my thinking was to check it tomorrow morning and see if has leaked out again. The battery charger is on right now.

Good idea...the batteries will be charged by tomorrow and if the hpop is down you can fill it. Also, I seem to remember a relay that can go bad and prevent startup (help anyone). Do you know if the GPR is working correctly (this is a longshot, but I don't know the temperature in your neck of the woods)?

Yes there is a relay for the IDM you can swap it with the blower relay but if he's getting smoke he's getting fuel pulse, he may still have some air in it some times it takes a lot of cranking on an empty top end I know every one is going to blast me but I would hit it with a 2 second shot of either or propane with the glow plug relay disabled, and see if the added fuel will initiate a run condition and then you can start eliminating air entrapment as a cause of your non start, if you are not comfortable with starting aids I can assure you in 25 years I have yet to experience a engine failure or part failure du to their use and they can be very helpful in a situation like yours!
