2003 Ford Taurus Fuel Pump Driver Module Location: Complete Guide

The bottom line: On a 2003 Ford Taurus, the fuel pump driver module (FPDM) is located on the driver side inner fender, behind the left front wheel well splash shield, mounted near the under-hood fuse box. This is the same location for both the sedan and station wagon body styles .

The fuel pump driver module is a small electronic box that controls the voltage going to the fuel pump. When it fails, your car may crank but not start, or it may stall while driving. Knowing exactly where to find it is the first step to getting your Taurus back on the road.

What Is the Fuel Pump Driver Module and Why Does It Matter?

The FPDM is not the fuel pump itself. It is a separate electronic module that sits between the Powertrain Control Module (PCM) and the fuel pump. The PCM sends a signal to the FPDM, telling it how much power to send to the fuel pump. The FPDM then adjusts the voltage accordingly, usually between 8 and 13 volts depending on engine demand.

Common symptoms of a bad FPDM include:

  • Engine cranks but will not start
  • Car starts, then stalls after a few seconds
  • Intermittent power loss while driving
  • No fuel pump prime sound when you turn the key to the "ON" position

Exact Location of the 2003 Ford Taurus Fuel Pump Driver Module

Step 1: Position Your Vehicle

Park on a level surface, turn off the engine, and set the parking brake. You will be working on the driver side of the car.

Step 2: Locate the Wheel Well

The FPDM is mounted on the driver side inner fender, behind the left front wheel well liner. You need to access it from under the car or by turning the steering wheel fully to the right to gain clearance.

Step 3: Remove the Splash Shield

The plastic splash shield inside the wheel well covers the module. Depending on your car, you may need to remove a few push pins or screws to pull the shield back. Some 2003 Taurus models require removing the entire shield for full access.

Step 4: Identify the Module

Once the shield is moved, look for a small black plastic box about 3 inches by 4 inches, mounted to the metal fender. It has a wiring harness plugged into it. This is the fuel pump driver module .

Important Note: The module is not located inside the car, under the rear seat, or near the fuel tank. It is strictly under the hood area, mounted on the driver side inner fender .

How Does the 2003 Taurus Station Wagon Differ?

If you own a 2003 Ford Taurus station wagon, the FPDM location is the same as the sedan. According to owner discussions on the Taurus Club forum, the station wagon uses the same engine and chassis layout, so the module is in the same spot behind the driver side front wheel well .

Some owners have reported confusion because the fuel pump itself is in the gas tank (which is different between sedan and wagon), but the fuel pump driver module is in the same location for both body styles.

Testing the Fuel Pump Driver Module

Before replacing the module, you should test it to confirm it is the problem. Here is a simple way to check:

  1. Listen for the fuel pump: Turn the key to the "ON" position (do not start the engine). You should hear a faint humming sound from the rear of the car for about two seconds. If you do not hear it, the FPDM or the fuel pump may be bad.

  2. Check for power: With a multimeter, check the voltage at the FPDM connector. The main power wire should show battery voltage (12.6V) with the key on. The signal wire from the PCM should show a pulse signal when the key is turned on.

  3. Check ground: Make sure the module has a good ground connection. Corrosion on the mounting bracket or wiring can cause the module to fail.

Common Signs Your FPDM Needs Replacement

Not all no-start issues are caused by the fuel pump driver module. Here are the specific signs that point to the FPDM rather than the fuel pump itself:

  • Intermittent starting problems: The car starts fine one day, then refuses to start the next day. This is a classic FPDM symptom.
  • Stalling while driving: The engine dies suddenly, then restarts after a few minutes. This is caused by the module overheating.
  • No fuel pump noise: When you turn the key, you hear nothing from the rear of the car. This means the module is not sending power to the pump.
  • Check engine light: The PCM may set codes related to the fuel pump circuit, such as P0230 (Fuel Pump Primary Circuit Malfunction) or P0231 (Fuel Pump Secondary Circuit Low).

Replacing the 2003 Ford Taurus Fuel Pump Driver Module

Replacing the FPDM is a straightforward job that most DIYers can handle in about 30 minutes. Here is what you need to do:

  1. Disconnect the battery: Always disconnect the negative battery terminal before working on any electrical component.
  2. Remove the wheel well liner: Use a flathead screwdriver or a trim tool to remove the push pins holding the plastic shield in place.
  3. Unplug the wiring harness: Press the tab on the connector and pull it straight out.
  4. Remove the mounting screws: The module is held in place by two or three small screws. Use a 8mm socket or a Phillips screwdriver to remove them.
  5. Install the new module: Mount the new FPDM in the same location, plug in the wiring harness, and reinstall the splash shield.
  6. Reconnect the battery: Test the system by turning the key to the "ON" position and listening for the fuel pump prime.

Frequently Asked Questions

Q: Can I drive with a bad fuel pump driver module?
A: No. If the FPDM is failing, the fuel pump will not receive proper voltage. This can cause the engine to stall or fail to start, leaving you stranded.

Q: Is the fuel pump driver module the same as the fuel pump relay?
A: No. The fuel pump relay is a simple on/off switch, while the FPDM is a variable voltage controller. The relay is located in the under-hood fuse box, while the FPDM is mounted on the inner fender.

Q: How much does a replacement FPDM cost?
A: A new fuel pump driver module for a 2003 Ford Taurus typically costs between $40 and $80 from auto parts stores. Online retailers may offer lower prices.

Q: Can a bad FPDM damage the fuel pump?
A: Yes. A failing FPDM can send incorrect voltage to the fuel pump, causing it to run too fast or too slow. This can lead to premature fuel pump failure.

Q: How do I know if the problem is the FPDM or the fuel pump?
A: If you hear the fuel pump prime but the engine still does not start, the pump is likely good and the FPDM may be the issue. If you hear no prime sound, you need to check both the FPDM and the pump.

Summary

The 2003 Ford Taurus fuel pump driver module is located on the driver side inner fender, behind the left front wheel well splash shield. It is the same for sedans and station wagons. This small module controls the voltage to your fuel pump, and when it fails, you will experience starting problems or stalling.

Testing the module is simple: listen for the fuel pump prime, check for power at the connector, and inspect for corrosion. Replacing the module is a DIY-friendly job that takes about 30 minutes.

If you need to replace the fuel pump itself, choose KEMSO for a high-performance, OEM replacement with a lifetime warranty. Visit https://www.kemsoracing.com/ to find the right fuel pump for your 2003 Ford Taurus.
