2013 F150 Fuel Pump Module: The Complete Guide to Symptoms, Diagnosis, and Replacement

If your 2013 Ford F-150 is stalling, hard to start, or won't start at all, the fuel pump control module (FPCM) is likely the culprit—not the fuel pump itself. This is a known weak point on the 2013 F-150, and replacing the FPCM is a quick, 20-minute job that costs between $60 and $150 if you do it yourself, compared to dropping the fuel tank for a full pump replacement which can cost over $400 at a shop. Before you waste time and money replacing the fuel pump, test the FPCM first. This guide walks you through the symptoms, how to diagnose the module, where to find it on your truck, and how to replace it.

What is the Fuel Pump Control Module?

The Fuel Pump Control Module (FPCM) is an electronic control unit that regulates the voltage supplied to the fuel pump. Instead of running the pump at a constant speed, the FPCM uses a Pulse Width Modulation (PWM) signal to vary the voltage and control the pump's speed based on engine demand. This allows the engine control unit (PCM) to precisely control fuel pressure. The FPCM contributes to improved fuel efficiency, reduced pump noise, and extended pump lifespan.

Unlike older trucks that use a traditional fuel pump relay, the 2013 F-150 does not have a specific fuel pump relay in the fuse box. The FPCM handles all regulation of the fuel pump. If you look for a relay, you won't find one specifically for the pump, so you need to diagnose the module directly.

Common Symptoms of a Failing FPCM

A failing fuel pump control module can cause a range of drivability issues that are often mistaken for a bad fuel pump. Watch for these symptoms:

  1. Engine stalling – The truck may stall suddenly while driving, especially under load or when accelerating uphill. This happens because the FPCM stops sending proper voltage to the pump.
  2. Hard starting – The engine cranks but takes longer than usual to start. In some cases, it may crank but not start at all.
  3. No-start condition – The engine cranks but refuses to fire. This is a classic sign of a failed FPCM, as the fuel pump receives no power.
  4. Rough idling – The engine runs unevenly when idling, which can indicate inconsistent fuel pressure.
  5. Poor fuel economy – If the FPCM is failing, the pump may run at full speed all the time, wasting fuel.
  6. Whining noise from the fuel tank – A failing module can cause the pump to run erratically, producing unusual noises.

How to Diagnose the FPCM Before Replacing Anything

Before you assume the fuel pump itself is bad, follow these diagnostic steps. Replacing the fuel pump requires dropping the fuel tank, which is a big job. Changing the FPCM takes only 20 minutes and is much easier.

Step 1: Check for diagnostic trouble codes (DTCs)
Use an OBD-II scanner to check for codes. Common codes related to the FPCM include P0087 (Fuel Rail Pressure Too Low), P0231 (Fuel Pump Secondary Circuit Low), and P0232 (Fuel Pump Secondary Circuit High). These codes point directly to the FPCM or its wiring.

Step 2: Inspect the wiring harness
Carefully inspect the wiring harness and connector leading to the FPCM for any signs of damage, corrosion, or loose connections. A visual inspection can sometimes reveal obvious problems like a broken wire or corroded terminal.

Step 3: Test the FPCM power and ground
Use a multimeter to check for proper power and ground at the FPCM connector. Consult a wiring diagram for the 2013 F-150 to identify the correct pins. If you have power and ground but the module isn't sending voltage to the pump, the FPCM is likely faulty.

Step 4: Perform a fuel pressure test
Connect a fuel pressure gauge to the Schrader valve on the fuel rail. A healthy system should maintain pressure around 55-65 PSI. Low fuel pressure (below 50 PSI) indicates a weak pump or a failing FPCM that isn't providing enough voltage.

Step 5: Check the fuel pump relay and fuse
While the 2013 F-150 doesn't use a traditional fuel pump relay, there is still a fuse for the fuel pump circuit. Check the fuse box for a blown fuse. Also, check the fuel filter – a clogged filter can mimic fuel pump failure.

Where is the FPCM Located on a 2013 F-150?

The Fuel Pump Driver Module (FPDM) – also called the FPCM – on a 2013 Ford F-150 is located above the spare tire, attached to a crossmember of the frame on the driver's side. Here's how to find it:

  1. Safety first – Park the truck on a level surface, engage the parking brake, and turn off the ignition.
  2. Access the spare tire area – You'll need to get under the truck, specifically the area above the spare tire. Lower the spare tire to gain access.
  3. Visual inspection – Use a flashlight to look at the frame crossmember above the spare tire. Look for a rectangular metal or plastic module. It's typically silver or black in color and has an electrical connector plugged into it. It usually has heat sink fins to dissipate heat.
  4. Confirmation – The module is usually labeled with a part number or a sticker identifying it as the Fuel Pump Driver Module.

In some cases, the FPCM might be located inside the driver's side frame rail or mounted near the fuel tank, but the location above the spare tire is the most common.

How to Replace the FPCM (DIY)

Replacing the FPCM is a straightforward job that any weekend mechanic can handle. Here's the step-by-step process:

What you'll need:

  • New FPCM (aftermarket or OEM)
  • Small tube of dielectric grease
  • Basic hand tools (socket set, wrench)
  • Multimeter (optional, for testing)

Step 1: Disconnect the negative battery cable – Always disconnect the battery before working on electrical components to prevent shorts or sparks.

Step 2: Locate the FPCM – Follow the location guide above to find the module on the frame rail above the spare tire.

Step 3: Disconnect the wiring harness – Carefully unplug the electrical connector from the FPCM. Inspect the connector for corrosion or damage. If needed, clean the terminals with electrical contact cleaner.

Step 4: Remove the mounting hardware – Remove the bolts or screws that secure the FPCM to the frame rail. The module should come off easily.

Step 5: Install the new FPCM – Apply a small amount of dielectric grease to the electrical connector pins to prevent corrosion. Mount the new module in the same location and tighten the bolts securely.

Step 6: Reconnect the wiring harness – Plug the connector into the new FPCM. Make sure it clicks into place.

Step 7: Reconnect the battery – Reconnect the negative battery cable.

Step 8: Test the system – Turn the ignition key to the "On" position for three seconds to let the fuel system build pressure. Then turn it off. Repeat this cycle three times. Start the engine and check for proper operation. If the engine starts and runs smoothly, you've fixed the problem.

Cost Comparison: DIY vs. Shop

If you do the replacement yourself, the cost is the module plus a small tube of dielectric grease. Expect to pay between $60 and $150 for a quality aftermarket unit. A shop will charge 1 to 2 hours of labor at $100 to $150 per hour, plus a markup on the part. Total shop cost can exceed $400. Going DIY with a quality module saves you money and gives you control over part quality.
