This on new rebuild, done at a shop.[this shop is OK done other work for me] Started with electric gauge checked with mech. no pressure. pulled the gauge only drips from the tube. Changed oil again, same. Pulled the pan and pump [looks new as the invoice said]. The engine fired right up and sounds good. With the pan off I can see assemble lube here and there. Put air up the pump hole via rubber stopper no bubbles from my oil pressure tube. Plain C maybe D. Any ideas where to look next, or how check things further.
 
Call the shop that built it ! ASAP just to make sure they can't come back and void any warranty. How close is the pickup from the pan ? Did they assembled the engine and the pan ? , intake ?

Hay the pickup tube might be a thing, I'm going to look in to that[ something else to check, thanks]
 
You can check your oil gallery plug to make sure it is installed. It should have been removed for cleaning.
 
Maybe they forgot the idler gear in the back. You should get some oi pressure from just turning the stater with the spark plugs out.
 
All good ideas and a pile of help. Takes me awhile to check each one. Still looking, this engine is all WAS all together with all the body fluids in it.
 
You don't want it too close , sometimes the pickup is too close and can't suck the oil it's blocked by the oil pan
 
Return it to the builder... No need to chase rabbits, if the builder is a "good guy" I am sure that he would rather find and fix the issue than have someone else "maybe" get it to work Chap
 
Had a day to think about this oil pressure problem. I made a plug with place to put some air into the block. Doing so there seem to be a lot of air exiting some where in the block. This laying on my back holding the hose and a light trying look and lesson. I've seem a picture of the oil system here [ford barn] and it looks like there should not be any where for mass amount of air to come out. I understand how the system works so I think or guess that there may be hole that is not suppose to be in the system. I wonder if I can make some sort low pressure pump to push oil up the oil pump hole so I can see something. Does this sound like a workable plan? I maybe thinking out loud. Thanks for all your replies .
