Check fuel pump fuses and relay. When you first turn key to on you should hear the fuel pump whine for a couple seconds then shut off.
Need to test fuel pressure. Not just if its there. Also see how long the pressure stays. Supposed to be 55psi min and hold above 50psi for 10 min. My truck stays pressureized for more than 24hrs.

If I pump the pedal the truck will stay running and even drive (unless is try going up a hill) then it just slows down , it doesn't idle without fuel pedal pumping either
