My 2001 ford f 150 Started stuttering and idling weird so I turned it off and it never started again. Please replace the fuel filter check this Relays and they’re good unscrew the valve on the fuel line rested in and some gas dripped out. Check the inertia switch and it was still engaged. Any suggestions before I replaced the fuel pump .

 

Press the Shrader valve on the fuel rail and see if gas comes out. Then try and start it again. Press the Shrader valve again. If no fuel comes out there's a good chance your pump needs replaced.
