first start up -no oil pressure,with remote oil filter
F
started my 5.3 today, ran it twice in 5 seconds increments. I'm getting no oil pressure using a mechanical oil press gauge, pulled the valve covers- no oil in any of the rockers.
I'm running a 7qrt milodon pan and pick up tube with a remote oil filter, I was thinking I could have mixed up the oil lines to the filter. I pulled the filter it was filled with oil.
pickup tube- ring issue?
bad oil pump?

I ran the motor a few times today in 10 second increments, pressure built to the gauge, fluctuating from 20-30 psi at idle, but still no oil come up the pushrods- I'm a bit afraid to run the motor any longer.
does it sound like a chunked up pickup tube o-ring?

I did the same,unplugged the coils and injectors.Cranked for 20second.Then stopped and waited a minute,cranked another 20 seconds and had 30psi oil before I fired up my lq4.Running the motor for 10 seconds is too short to build pressure and cycle through.If I were you I would prime it again with the covers off and see if oil come up.Then start it,some guys have 30-40psi on idle so thats not bad.I get 40psi at idle,if you rev and dont build up more pressure..I would be concerned.I get about 55-60psi in upper rpms on stock pump.
