2015-2020 Ford Edge, Focus, Transit Connect & Nautilus Fuel Pump Driver Module Failure: Stalling, No-Start & Replacement

Symptoms of a Failing Fuel Pump Driver Module

A bad fuel pump driver module can mimic a failed fuel pump, often causing symptoms that appear suddenly and can leave you stranded. The most common sign is an engine that cranks but refuses to start, as if it's out of gas. You may also notice the distinct lack of a 2-3 second humming sound from the rear of the vehicle when you first turn the key to the 'On' position—this is the sound of the fuel pump priming, and its absence points to a power delivery issue.

• Engine Cranks But Won't Start: This is the most definitive symptom. The starter motor turns the engine over, but it never fires and runs because no fuel is being delivered.
• Sudden Engine Stalling: The vehicle may stall without warning while driving, which can be extremely dangerous. The engine cuts out completely, and you may lose power steering and braking assist.
• Intermittent Stalling or Hard Starting: The module may work sporadically, causing the engine to stall unpredictably and then restart later, or require long cranking times to start.
• Engine Hesitation or Surging: Under acceleration, the engine may stumble, hesitate, or surge as the module fails to provide consistent voltage to the fuel pump.
• Check Engine Light: A failing FPDM will often trigger the Check Engine Light.

Common OBD-II Diagnostic Trouble Codes (DTCs)

If your Check Engine Light is on, a code scanner may reveal codes that point directly to the FPDM or the circuit it controls. Common codes include:

• P1233: Fuel Pump Driver Module Offline
• P0627: Fuel Pump "A" Control Circuit / Open
• P0191: Fuel Rail Pressure Sensor Circuit Range/Performance
• P1235: Fuel Pump Control Out of Range

Known Issues, Recalls, and Technical Service Bulletins (TSBs)

While this specific part has been a common failure item on many Ford vehicles, most formal recalls target older models or different components. Here's what is relevant to this group of vehicles:

• Ford Transit (2015): Ford issued Customer Satisfaction Program 20B53 for certain 2015 Transit models due to premature failure of the fuel pump control module. The program, which has since expired, provided a free replacement at the dealer. This acknowledges a known defect in the part for this model year.
• Ford Focus (2012-2018): A major recall, 18S32, addressed a faulty Canister Purge Valve (CPV) that could create excessive vacuum in the fuel system, leading to stalling. While not a direct FPDM failure, the repair procedure could involve replacing the "fuel delivery module" if certain fault codes were present, making it a related issue for Focus owners experiencing stalling.

Vehicle-Specific Replacement Information

The difficulty and location of this repair vary significantly depending on which vehicle you own.

2015-2020 Ford Edge & 2019-2020 Lincoln Nautilus

• Location: The module is located on the underside of the vehicle. It is bolted to the rear subframe on the driver's side.
• Difficulty: Moderate. The vehicle must be safely raised on a lift or jack stands. Access is relatively straightforward once the vehicle is lifted. The main challenge is often dealing with rusted bolts.
• Replacement Notes: The replacement part should come with new bolts and rubber spacers. These spacers are critical—they create an air gap between the new aluminum module and the steel frame, preventing the corrosion that caused the original part to fail.

2017-2018 Ford Focus

• Location: Inside the vehicle's cabin, protected from the elements. Sources indicate it is located under the rear seat cushion on the passenger side, beneath the carpet.

• Difficulty: Easy to Moderate. This repair does not require lifting the vehicle but does involve removing the rear seat bottom cushion and pulling back interior trim and carpet to gain access.

2018-2020 Ford Transit Connect

• Location: On top of the fuel tank.
• Difficulty: High. This is the most difficult replacement of the group. Accessing the module requires the fuel tank to be drained and dropped from the vehicle. This is a significant job that may be best left to a professional.

Does the Fuel Pump Driver Module Require Programming?

This is the most common question for this repair. For a direct replacement with a new or used OEM part matching your vehicle's original specifications, the answer is generally no, programming is not required. The process is typically plug-and-play. After installing the new module, you should use a scan tool to clear any existing fault codes from the computer's memory.

Buying a Used Fuel Pump Driver Module

A used OEM module is an excellent, cost-effective alternative to an expensive new dealer part. Since these modules are generally plug-and-play, a used part from a compatible vehicle is a great option for DIY repair. Here's what to look for:

• Inspect the Housing: The number one killer of these modules is corrosion. Avoid any unit with heavy white, chalky oxidation on the aluminum case, especially around the seams and mounting points. Look for cracks or holes in the casing.
• Check the Connector: Look at the electrical connector pins. They should be clean and straight. Avoid any module with green, corroded pins or any signs of melting or black soot, which indicates an electrical short.
• Verify the Part Number: Match the OEM part number exactly. The correct service part is F1FZ-9D370-B, which supersedes F1FZ-9D370-A and F1FA-9D370-GA.
• Ask for Mounting Hardware: For Edge and Nautilus owners, ask if the seller can include the original bolts and spacers. These are essential for preventing future corrosion.

Cost of Replacement

The cost to replace the FPDM can vary widely based on the part source and who performs the labor. For a Ford Transit Connect, labor costs will be significantly higher due to the need to drop the fuel tank.
