Looking for FPDM LOCATION IN 1997 LINCOLN TOWN CAR


What is causing you to look for the FPDM? According to the factory service manual, your 1997 Town Car with 4.6L V8 does not have an FPDM. At least none is listed in the Fuel Charging and Controls section.

Were is fpdm located on 2002 f150 4.6 motor ?


If your talking about fuel pump driver module, separate from the fuel pump assembly, You don't have one that I can find. Not in the wiring diagram, the fuel pump assembly is called a module. I looked at ford partsbook for fpdm, not in there either. You do have a fuel pump shut-off/inertia switch. Do you want a wiring diagram for fuel pump?
The picture is location of inertia switch. I found the info in your owners manual.

I have explorer 2006 fuel pump doesn't work although it is new i want adiagram for its electric sircut


Did you test or just replace it ? There is a fuel pump driver module that controls the pump , an the PCM tells how much fuel to pump by a sensor on the fuel rail ! the fuel rail pressure sensor ! Your vehicle has Ford Electronic Returnless Fuel System ! watch this guy on testing Ford Electronic Returnless Fuel System Diagnosis Part 1 Ford Electronic Returnless Fuel System Diagnosis Part 2

did you check Inertia Fuel Shutoff (IFS) Switch The IFS switch is used in conjunction with the electric fuel pump. The purpose of the IFS switch is to shutoff the fuel pump if a collision occurs. It consists of a steel ball held in place by a magnet. When a sharp impact occurs, the ball breaks loose from the magnet, rolls up a conical ramp and strikes a target plate which opens the electrical contacts of the switch and shuts off the electric fuel pump. Once the switch is open, it must be manually reset before restarting the vehicle. Refer to the Owner's Literature for the location of the IFS.
Fuel Pump Driver Module (FPDM) Note: For the LS, the FPDM functions are incorporated in the rear electronic module (REM). The fuel pump operation is the same as for applications using the stand-alone FPDM. However, the REM communicates diagnostic information through the communication link instead of using a fuel pump monitor (FPM) circuit.
Note: The Ford GT uses 2 FPDMs to control fuel for the dual-injection fuel delivery system. The PCM outputs only one fuel pump duty cycle which is used by both pumps. The PCM individually monitors the FPDMs through their fuel pump monitor circuits. Both FPDMs are mounted on the same bracket. The FPDM mounted in the upper position on the bracket is referred to as FPDM and the FPDM mounted in the lower position, is referred to as FPDM2.
The 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 on Fuel Pump Control and the Fuel Pump Monitor, refer to Fuel Systems in this section. You need to do some research on line. depending on the location these FPDM corrode an short out ! This vehicle in the video is inside but on some trucks they are underneath the vehicle ! This guy here scanner danner is a automotive teacher an knows he's stuff !

P1233 code


ford 1233
lost spark? on 1 or all cylinders?
did you google this? 18,000 hits. just for this.
example

P1233 - Fuel System Disabled or Offline
Description:

The PCM monitors the fuel pump monitor (FPM) circuit from the fuel pump driver module (FPDM). With the key on, the FPDM continuously sends a duty cycle signal to the PCM through the FPM circuit. The test fails if the PCM stops receiving the duty cycle signal.

Possible causes:

Inertia fuel shutoff (IFS) switch needs to be reset
Open FPDM ground circuit
Open circuit to FPDM PWR RLY
Open FPDM PWR circuit
Open or shorted FPM circuit (engine should start)
Damaged IFS switch
Damaged FPDM PWR RLY
Damaged FPDM
Damaged PCM

Fuel pump driver module


Could have a problem with the fuel pump, partially blocked or seized and drawing too much current thru the FPDM. Also, pinched fuel line on either side of the pump or v dirty fuel filter could also cause pump to work too hard. Can you put a smaller fuse inline with pump motor, so that it blows before FPDM is damaged?

What side is the fuel pump for 2002 lincoln ls v6


2002 Lincoln LS uses a saddle-type fuel tank consisting of 2 fuel pump modules. A fuel transfer pump in the left side of the fuel tank supplies fuel to the right half, which contains The Fuel Pump Module (FPM). The FPM contains the fuel level sensor and an inlet filter. The FPM is controlled by the Fuel Pump Driver Module (FPDM) which is integrated into the Rear Electronic Module (REM) Fuel pressure is regulated by a pulse-width modulator in the FPDM which cycles the fuel pump on and off at varying intervals depending on engine load and RPM. The FPM supplies fuel under pressure to the fuel injection system supply manifold and a fuel level signal to the fuel gauge on the instrument panel.
It is recommended that if one of the fuel pumps fail that BOTH pumps be replaced as a set to avoid repeat repairs. (If one pump has been running for 1500 hours and the motor is worn out, the other pump also has been running for 1500 hours and is very likely to fail shortly thereafter.)

How do I fix code P1237 on ford taurus sel


P1237 - Fuel Pump Secondary Circuit Malfunction

Electronic Returnless Fuel Systems (ERFS) utilize a Fuel Pump Driver Module (FPDM) to control fuel pressure. The PCM uses a Fuel Rail Pressure Sensor (FRP) for feedback. The PCM outputs a duty cycle to the FPDM to maintain the desired fuel rail pressure. During normal operation, the PCM will output a FP duty cycle from 5% to 51%. The FPDM will run the fuel pump at twice this duty cycle, e.g. if the PCM outputs a 42% duty cycle, the FPDM will run the fuel pump at 84%. If the PCM outputs a 75% duty cycle, the FPDM will turn off the fuel pump.

If the FPDM does not out any diagnostic signal, (0 or 100% duty cycle), the PCM sets a P1233 DTC. This DTC is set if the FPDM loses power. This can also occur if the Inertia Fuel Switch is tripped.

If the FPDM outputs a 25% duty cycle, it means that the fuel pump control duty cycle is out of range. This may occurs if the FPDM does not receive a valid control duty cycle signal from the PCM. The FPDM will default to 100% duty cycle on the fuel pump control output. The PCM sets a P1235 DTC.

If the FPDM outputs a 75% duty cycle, it means that the FPDM has detected an open or short on the fuel pump control circuit. The PCM sets a P1237 DTC.
