No oil pressure

[ITSME4G63]

THis past weekend we were all ready to start my friends car after a rebuild. We tried to prime it but saw no oil shooting out in the valvecover, took off a oil cooler line at the oil filter housing and no oil, wtf! We've assumed/cvoncluded this must be due to a failed opil pump, but I thought Id ask here jsut for sure, no matter how many times wed crank it, no oild pressure, the oil just stayed in the pan. SO it seems as if the oil pump siezed up. Any input appreciated, going to be takin it apart this weekend....again.

How did you try to prime the engine?

pick up could be blocked or something got in the gears and stopped it is your timing belt moving freely from the oil pump sproket?

took it apart yesterday, something went wrong with the pump, it turned byt not as easy as the replacement new warantee one did, so putting new on in tomorrow and will prime it via air tool before puttign the tbelt on.

Disassemble the pump, make sure the gears have no burrs, thoroughly clean everything with soap and water, blow everything dry, put assembly lube on the gear shafts and then assemble the pump. Once you are done, turn it upside down and squeeze some white grease in the pick-up passage (before you put the pick-up tube on) turn the pump to suck that grease up. Once you see that you are getting suction you can install the front case on the block and so on. Turning the pump with a drill is the second best option to prime the engine because nothing can beat using a pre-lube pressurized tank.
Good luck.

We'd take apart that pump, but since we got a brand new one for free of charge, just gonna put that in and send the old one back. The new one spins so nicely.

You don't listen to what I say. Am I not clear enough?
I'm talking about what you should do with the new one before assembly!!! Plus you have the stubby shaft to install, at least you should be doing that.

Definitly do what suparata said to do with the new pump. I didn't bother checking one of my old pumps and just put some grease in the pickup tube and installed it. It was also a little harder to spin than a few others I had seen but the others I'd seen were used so I figured there was still oil inside those allowing it to spin easier. Needless to say roughly 8000 miles later it died and a rod bearing went bye bye.
