Fuel Pump Driver Module
Note: For the Thunderbird and LS6/LS8, the FPDM functions are incorporated in the Rear Electronic Module (REM). Fuel pump operation is the same as applications using the stand-alone FPDM. The REM will, however, communicate diagnostic information through the BUS +/- circuits (SCP) instead of using a fuel pump monitor (FPM) circuit.
The fuel pump driver module (FPDM) receives a duty cycle signal from the PCM and controls the fuel pump operation in relation to this duty cycle. This results in variable speed fuel pump operation. The FPDM sends diagnostic information to the PCM on the fuel pump monitor circuit. For additional information, refer to PCM Outputs, Fuel Pump and PCM Inputs, Fuel Pump Monitor in this section.

Testimonial: "Thanx for info..no wonder I couldn't find Relay! "
possible just not probable. you need to see if there is any pressure to fuel rail. if not youre going to have to by pass the fuel pump and see if it is getting voltage. if so then apply a seperate voltage and ground wire to the pump to see if it kicks on. come to think of it, it could be the PATS system(security) that shuts down the system. it will crank but will not fire. your ford dealer will need to reprogram the system.

the enginr oil pressure switch runs the fuel pump till the oil pressure is up to the normal operating range. When the pressure is up the relay kicks in and takes over the power to the pump. The oil pressure switch my be at fault if you can no hear the pump running when you turn the key on

It is on the passenger side of the engine compartment under the wiper panel. its deep in because of the body design. you'll see a relay box. It should click on and then quickly off when the key is turned to run without starting the engine
