2006 6.0 no oil pressure

[huserfarmer]

I have been working on this about a week and haven't figured it out yet, need some advice. It quite running on me and i replaced the stc fitting on high pressure oil pump, ran good for about a week. I left it idling for a minute and it all the sudden went to full rpms. It went back down to idle and then thats all it would do was idle. When i shut it off it wouldn't start back up, shows no oil pressure on the dash, put new high pressure oil pump on, new ipr valve on top of pump, checked lpop, looked good, oil pressure valve on front cover of lpop wasn't stuck, oil filter housing doesn't fill, when i put air to oil branch tubes were stc fitting connects i don't here air leek, but i do when i putt air to sensor port on passenger side valve cover, not sure were to go from here, any suggestions? Sorry about bad spelling

You have a way to monitor ICP pressure and IPR duty cycle?

Your number one problem is in bold. LPOP has to pump oil first, and it isn't if the housing doesn't fill.

I have a snap-on solis, it might monitor the icp and ipr, but i have no idea how to go about doing this. I think im going to go ahead and replace lpop and pressure regulator and see what that gets me, i know throwing parts at it is the wrong way to do it

Those PID's aren't going to matter if the LPOP is not working.

I read the post wrong and thought it said that the filter housing does fill with oil.
