I recently had a shop swap out injector 5 on my truck. It ran great for 2 days I parked it and no it won't start. I checked to fuel filter on top of the engines and there's no fuel in the housing. I loosened the fuel filter cap on the fuel pump and no fuel came out.

Good morning,

Can you hear the primer pump run down on the frame by the drivers door?

I attached the procedure and the wiring diagram for you to view to test for power.
