Where is the fuel pump driver module on a Ford 500?
The fuel pump driver module (FPDM) is a critical component in your Ford 500, responsible for regulating the voltage sent to the fuel pump. If you're experiencing issues such as difficulty starting your car, stalling, or inconsistent fuel delivery, the FPDM might be the culprit. Knowing its location can help you diagnose and address potential problems more effectively.
Understanding the Role of the Fuel Pump Driver Module
The FPDM works as an intermediary between the fuel pump and the engine control module (ECM). It ensures that the fuel pump receives the correct amount of voltage based on the engine's needs, optimizing fuel efficiency and performance. A malfunctioning FPDM can lead to erratic fuel delivery, which may cause engine performance issues.
Location of the Fuel Pump Driver Module in a Ford 500
In the Ford 500, the fuel pump driver module is typically located in the trunk area. Specifically, you can find it:
- Behind the trim panel on the driver’s side of the trunk.
- Mounted near the rear seat or close to the wheel well.
To access the FPDM, you may need to remove the trunk liner or trim panel carefully. Be sure to disconnect the battery before working on any electrical components to avoid injury or damage to the vehicle's systems.
Steps to Access and Inspect the FPDM
If you suspect an issue with the FPDM, follow these steps to locate and inspect it:
- Open the trunk and remove any items obstructing access to the trim panel on the driver’s side.
- Carefully remove the trim panel or liner to expose the FPDM.
- Inspect the module for signs of damage, corrosion, or loose connections.
- If necessary, disconnect the wiring harness and remove the module for further testing or replacement.
When to Seek Professional Help
While accessing the FPDM is relatively straightforward, diagnosing and repairing it may require specialized tools and expertise. If you're unsure about handling this component or if the issue persists after inspection, it's best to consult a professional mechanic.

Frequently Asked Questions
How much does it cost to replace a fuel pump module?
How Much Does a Fuel Pump Driver Module Replacement Cost? The cost of an aftermarket fuel pump driver module replacement can range between $100 to $550 for parts alone. Several factors affect pricing, such as brand and warranty. Labor can cost you an additional $125 to $300, depending on the rates in your area.
Where is the fuel pump driver control module located?
Once lowered, the fuel pump driver module is easily accessible underneath the vehicle. Depending on your application, the fuel pump driver module is either located on the rear Crossrail above the spare tire or on the rear frame wall.
What is a fuel pump driver module?
The Fuel Pump Driver Module controls the voltage delivered to a vehicle's fuel pump.
Will a bad fuel pump driver module throw a code?
If a problem develops in the FPCM, on-board diagnostics (OBD) will log a U0109 code.
How do I know if my fuel pump driver module is bad?
Some symptoms of a faulty FPDM include misfires, damaged fuel filters, and engine surges.
How long does it take to replace a fuel pump module?
about one to two hours
Fuel Pump Control Module Replacement Cost
With diagnostic time and labor, you can expect a professional to charge somewhere between $350 and $1300. It's a job that can be done in about one to two hours for most models, but it's possible yours could take longer if it's installed in a difficult-to-access location.
How do you clean a fuel pump module?
If your vehicle has an electric fuel pump, you can use a fuel system cleaner to clear any sediment buildup or blockage. If you have a manual one (usually found in older model vehicles), you can actually open the pump to clear debris out of its internal filter, though that isn't an option in most modern vehicles.
Will a bad fuel pump module throw a code?
Intermittent problems – a failing fuel pump might sometimes cause intermittent issues that don't immediately trigger the check engine light but lead to pending diagnostic trouble codes that indicate a developing problem.
What is the code for Ford fuel pump driver module?
P025A Code: Fuel Pump Control Module Circuit / Open. Diagnostic trouble code (DTC) P025A stands for “Fuel Pump Control Module Circuit/Open.” The P025A code is logged once the powertrain control module (PCM) detects abnormal voltages in the fuel pump control module's circuit.
What happens when the fuel pump module goes out?
A faulty fuel pump module does not provide enough pressure to the fuel pump. Decreased fuel supply to the fuel pump will result in overheating of the engine. Contamination of fuel also leads to wearing out of the engine.
