Parked truck was running fine. Went to start it 2 days later just cranks. I can spray gas into the throttle body and it runs fine as long as I keep spraying fuel. I can hear the fuel pump kick on but no fuel pressure when I checked. I replaced fuel pump fuel filter, fuel pressure regulator and checked fuses and inertia switch. Nothing! I shot air from the fuel rail until I heard it bubble in gas tank thinking maybe some blockage. Nothing. I think I I listed it all. Any ideas?

Check valve in the pump should have stopped air from bubbling in the tank. That and the pump runs, no blockage in the lines but no pressure in the rail - I'd say pump's toast, most likely.
You did check fuel pressure with a gauge at the schrader valve, right ?

I did check with a fuel pressure guage on the rail and nothing. I replaced the fuel pump still and it's still the same no pressure
