No Start 2005

Tore 2005 f350 down to do HG and studs while in there did and egr delete and replaced oil cooler, put in stand pipes and dummy plugs, changed out the stc fitting and redone the HPOP o rings, put in new orings on ipr valve. Before trying to start poured oil in the oil filter canister to let go into oil cooler galley so there was nothing dry. Now got all this done and tried to start my truck with a computer hooked to OBD port while trying to start showed nothing at the icp sensor then checked icp sensor and it showed no oil in place where screwed into on oil rail after that took off valve and it showed no oil even in rocker box where I think should be wet in that area. Also pulled the canister filter out and it was still dry and the oil poured into in the beginning was still at the same level as when started. Can someone please help me where to turn to next, and also would like to know how to put air pressure in the system to here if there are any leaks in the system. Truck been down since Nov. 24 would love to here it run again.
