No offense, but your post isn’t the clearest. I’m guessing you said you blew a motor, replaced the motor and now the new motor is showing no oil pressure.
Who installed the motor?
Was the motor confirmed to be in good solid running condition when it was purchased?
Did the motor come with the oil pump installed?
Did you confirm that the o-ring on the pickup tube was good?
Is there oil showing on the dip stick?
Is the oil pressure sensor plugged in?
If there is oil in the oil pan, get an analog oil pressure gauge and see for sure where you’re at for oil pressure.
I purchased a used engine from a auto salvage yard that said it was in good working order when they took it out. They ship used engines daily. We installed a new oil pump when we installed the engine And a new pick up tube oil and oil filter oil pressure sensor is new and all wires are connected.
Yes we purchased a used engine from a salvage yard that ships used engines daily. We installed a new oil pump, oil pick up tube, filter, oil , oil sensor, checked the screen on the oil pressure sensor and the wiring and still no oil pressure. Bought a oil pressure test kit today and going to remove the oil pressure sensor and hook it up next to see if it reads anything. Is there something I'm missing or what could it be

An engine from a 2013 won't fit the 2021's.

Is it running with no oil pressure? or are you cranking it looking for oil pressure? If you didn't prime the pump it will never get oil pressure cranking it.
WE STARTED TO JUST CRANK IT OVER WITHOUT IT FIRING. then started it and no oil pressure. How am I supposed to prime it. We cranked it over quite a few times without it firing to try to prove it. Is there a certain way to get it to prove
is there a certain way to get it to prime

how do you prime the oil pump
When I installed a new oil pump on my Yukon, I removed the front cover of the pump and packed it about 25% full of synthetic grease to seal the rotor/housing gaps. Worked perfectly. You can do this without pulling the pan - just need to remove the harmonic balancer and timing cover, and anything in the way of getting them off.

Right side of front of motor down near the oil pump is a plug you can pull out and pump some oil in there. I will try to find the link I found before on it

Ha didn't see the post in between
I saw a video on that but what do I do after I fill that with oil
After I fill the oil pump with oil from the side port how should I proceed with continuing the prime and I am going to remove the oil pressure sensor and put an oil pressure test Guage on it after I do that and remove the Guage will I have to reprime the engine
Put the plug back in and start it up.
alright I'm keep my fingers crossed
