Default no pump it seems

Ive got an 05, crank but no start. Replaced the PEM with a known good one. No codes and my scanner is showing fuel pump relay active but,it has no fuel pump running. Anyone know a way to jump the fuel pump power to test it separately? I'm stumped...

...its definitely fuel related. Pulled the fuel rail and cranked it and got nothing. But there has to be a way to hotwire the fuel pump. If I can do that and have pump, it's electrical somewhere. If nothing, it's pump. I pulled all 5 plugs and poured a little full in each cyl, replaced plugs and coils and boom, ran for 2 seconds. Odd thing is, my scan tool shows when the fuel relay kicks on but no pump. I'm leaning to swapping the pump out but money is tight and I want to diagnose the correct issue.
