get a code reader like the Actron CP9015 Code Scanner, 20 dollars and will flash codes. if it will not diagnose itself, the ecm must be replaced. this fixed my dads truck with the same problem

The relay is more than likely in the fuse box under your hood.
I would check that box first, then the inside one.
I think it's in the battery box, I know in the older models it was there, number 301.

it is in the fuel tank.. drop the tank, remove little snap ring on top of tank, and pull the old fuel pump assembly out, then just replace the old one with the new one.. good luck keith...

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 :
