>You have oil pressure again...Do you now know what happened to cause the loss of oil pressure?

Nope...nada...

Perhaps the attempt after installing the replacement pump it did not prime...even though the impellors were packed with grease and oil. When we tested it we had all spark plugs off and we still had the oil pressure sender unit removed so there was an open hole so no oil squirting out lead me to believe something bad was going on down below...

Should have done what JWH suggested.

If someone has this issue after a new pump installation I would have someone squirt oil down the open oil pressure sender unit hole while I am using a flywheel tool to move the flywheel BACKWARDS and this should suck the oil backward down through the oil pump...about two flywheel turns backwards should do the trick. You would be able to see the open hole ingesting the oil if the pump is turning
