Check the fuel pump relay. There may also be an oil pressure switch in your fuel pump circuit. Load voltage for both may come from ecm B fuse. I'll have to check.

Not ecm B fuse, that load voltage comes from fusible link.

Ok. Well I know that the gray power wire to the fuel pump has no power and I have followed it up to the back side of my fuse box on the other side of the fire wall

Right side of firewall, battery junction block. There may also be an inline fuel pump fuse in that same location, close. My database is conflicting. As far as the fusible link, if you have voltage on both sides, the link should be ok.

Check the inline fuse and fusible link. The o/p switch and fuel pump relay, as far as voltage to the pump, should work independent of each other. The o/p switch may be located close to oil filter, driver side of engine, down low.

At the fusible link, if voltage on one side and not the other, get new fusible link.
