You didn't perchance take the engine mounted filter cartridge out?

Oops, just noticed the year and I know squat about 7.3's

Do you mean the engine will not spin or do you mean the engine will not fire/run?

There is a check valve in the center stem of the filter housing on a 7.3L, so if you leave the fuel filter out, no fuel gets to the engine.

After consulting a buddy we both went over everything and agreed install was correct. Turns out the air dog doesn't fill the water separator by priming. I filled the pre-filter before installing on the pump but not the water-separator. Since my dumb*** tried to start the truck so many times on top of leaving the door and hood open I needed to jump the truck. Once we got her started all was good
