My info says it is in the bcm. The bcm shows to be located below or behind glove box. The wiring diagram for fuel pump relay, doesn't show any terminal numbers for the relay. Sometimes that means the relay is soldered in and you can't pull it out. The fuse for fuel pump relay also shows to be located in bcm.
Make sure of your diagnoses before you start taking things apart.
I doubt I can help you much from where I'm sitting, I can't see anything from here.
Fuel pump relay should be located under hood in fuse box and fuse box should have relay marked out as fuel pump. Another way in owners manual there should be diagram of fuse and relay boxes and locations.
1999-2003 ModelsEngine Compartment fusebox - fuse #5, and relay #207
NOTE: You really need to have a diagram in front of you when looking for these specific fuse/relay locations. The Owners Manual is a good resource. Autozone's free online Repair Guide is another source of fusebox information and illustrations.
Fuel Pump relay switch is in the main box usually located on the drivers side Fender in a black box.
According to the owner's manual in the power distribution box in the engine
compartment (Ford recommends disconnecting your battery)
Relay # 5 is the fuel pump relay , and also in the PD BOX is a 20 amp mini-fuse
for the fuel pump relay + RAP module in location # 9
( P.S. - don't forget your fuel pump inertia switch , in the right front passenger area ,
by the right front kick panel )Sometimes this gets kicked by passenger or if the car is bummed hard it could set this item to shut down fuel system. Best of Luck
There is both a fuse and a relay for the fuel pumps electrical system. The image below of the Power Distribution Box is located in the engine compartment.
