Working fuel pump won't prime

So me and my buddies just got done dropping my fuel tank and removing the fuel pump, we plugged the new pump into the connector and turned the key to test it and nothing happened.

We also ran electric to both the old pump and new pump and found both pumps still work. My relay and fuse for the EFI are both good.

Now we're trying to troubleshoot any possible causes but we're pretty lost, any tips or suggestion wwouldbe really appreciated

 

Now I'm searching for the COR relay hoping that may help

 

I should've checked for that first but I didn't know it existed
