Hi skyewatcher, Welcome to 2carpros and TY for the donation If you can hear the fuel pump come On. Check the actual fuel pressure if its within specification, if okay check if the injectors are pulsing Also you replaced the fuel pump relay this means the inertia fuel cut off switch is okay if its coming On. 4.9L Below is the EWD-fusible link thru the fuel pump relay to inertia switch and then the fuel pump hru the brown wire-
