No oil pressure after engine swap and what I have tried so far

With the front cover off, pour oil down the screw-on oil filter tube while hand turning oil pump gears. If you get flow, good.
With oil pan off, pour oil through the removed oil pickup tube (you've got to turn it upside down to pour through the pickup screen). Do you get flow through it? If yes, then examine the tiny black o-ring on the non-screen end of that pickup tube. If it is OK, then firmly reinstall your oil pickup tube.
THEN you can button her back up and retry... but better would be replacing those rod bearings before reinstalling the oil pan. Also, having the oil pan off is an ideal time to shine a bright light upward to examine for a walked cam bearing.

I have another front cover from the old engine, so I am going to pull it this evening. I really wanted to test my theory that the issue was just a stuck valve. When I pull the cover off I will manually spin it and feed it some oil to see if it is pulling oil now.
Good news is that I had not filled it with oil yet, I was just making sure the oil cooler lines were full when I noticed the drip, so I still have the newly purchased oil
Everyone has been a great help so far, special thanks to The Deputy for calling me yesterday to talk through some things.

Am I missing something or are these pump gears different?
Gears on top are from the old engine that I pulled
gears on bottom installed are from the engine with no oil pressure
If the new engine was missing this piece then it makes sense that it would not be pumping
both pulleys are identical.

You mean it was missing the center gear on the original?? Dang man I thought in all the pics earlier you had that sitting to the side or something!!! Yes that will make an oil pump not pump! It has to have that center gear in order for the pump to spin off the crank.
If that's how it was when you pulled it then there is NO WAY that engine ever had oil pressure! Lets hope & pray someone installed a different front cover or something while it was out of the LR and then did a **** poor job and didn't install the gear.
