unplug the injectors 1 at a time to listen to change in the way i runs,locate the cylinder that doesnt really change and inspect the plug,wire and if good then it may be a dirty or clogged injector,try addind seafoam to the gas and drive it for a while,it may smoke for some time but it should clean the injectors and valves really good.if it used oil alot before it may be carbon on the valves which seafoam helps clean them or you can squirt cold water in a spray bottle into the intake while running and the water explodes the carbon off the valves but it can not be really hot or damage to the valves will happen

Did you check the fuel inertia switch in the passenger side kick panel ?
The fuel pump is powered :
the fuse to the fuel pump relay.
The fuel pump relay to the fuel inertia switch
The fuel inertia switch to the fuel pump itself.
At the fuel inertia switch in the kick panel, power from the relay is the Dark Green w/ Yellow stripe wire and the pink w/ black stripe wire is the power. from the fuel inertia switch to the fuel pump.
If you jumper the fuel pump relay, you should hear it run. If not pull the fuel pump relay, and check the pins in the relay socket, pin 30 should be the power from the fuse.
If you have power at pin #30, jumper the relay socket as shown with the red line above, and check the dark green w/ yellow stripe wire at the fuel inertia switch for power.
Press the button on the top of the fuel inertia switch, and check for power leaving the fuel inertia switch on the pink w/ black stripe wire.
This is tests good, check for power at the fuel pump, same pink w/ black stripe wire.
Fuel inertia switch info is in the owners manual, If you did not get an owners manual with your truck ( purchased used ), you can download one from Ford :
