Rebuilt my engine and installed the DOD Delete kit. Ran it, 0 oil pressure. Removed front hardware and timing chain cover, had oil in oil pump. Removed Valley cover. All O rings in place. Removed oil filter, full of oil, removed engine barbell in place, replaced it with new since motor was out. Also replaced oil pick up tube O ring also since engine was out. Put back in truck, still zero pressure, and yes valve cover off and no oil. I'm stumped. Help!
Already did that, Pulled spark plugs, disconnected coils, Pulled fuses, turned over numerous times, forever even, valve covers off and nota single drop off oil
You may want to remove oil filter and crank the motor coil harness disconnected so it won't start, it should gosh oil out the filter area, assuming oil in pan.
There should be a plug on the driver side of the block near the front of the engine close to the oil pan. Undo that plug and pump some oil in there. It sounds like the oil pump isn't primed.
Have you pulled the oil pressure sender and connected a mechanical gauge to see if you are actually having zero oil pressure?
Two options as this exact thing happened on a 6.0 build I did. You could remove the pump and pack it with petroleum jelly to get it to prime. Second, as already suggested is remove the plug after the filter and build yourself a cheap oil pump and prime the system directly. That is assuming everything is correct, the relief valve isn't sticking, etc. I would also hook up a mechanical unit to monitor pressure.
In our case, we chose option two. Even after putting roughly 9 quarts in the engine it didn't prime just turning it over with the starter. I assembled the engine myself and measured clearances so I knew everything was good and I was very generous with assembly lube, so we made the decision to start it up. Fired right up and after a few seconds oil pressure came right up. No issues whatsoever in 10k miles. Just know you do that at your own risk.
