How do I reset my fuel pump on my Ford?

Resetting a Ford fuel pump isn’t a single universal button you press. In most cases you re‑energize the system by dealing with the fuel pump safety switch (if equipped), checking the relevant fuse and relay, and cycling the ignition to prime the line. If the pump itself has failed, it may require replacement or professional diagnosis.

Understanding what may be reset and where to look

Ford vehicles vary by year and model, but these are the most common reset-related checks you can perform before getting deeper into diagnostics. The exact locations and availability depend on your specific car or truck.

• Inertia (safety) switch: a red button that cuts power to the pump after a collision or impact; must be reset after an event or if the switch trips.


• Fuel pump fuse: protects the circuit; a blown fuse will stop the pump from receiving power.


• Fuel pump relay: a separate control device; a faulty relay can prevent the pump from running even with a good fuse.


• Wiring/connectors: loose, corroded, or damaged wiring can interrupt power to the pump or its controls.


• Ignition cycling to prime: many Ford systems re-energize the pump when the key is turned to ON; cycling the ignition can help prime the system in some situations.

If any of these elements show signs of damage, wear, or improper function, addressing them is often enough to restore normal operation. For persistent problems, professional testing of fuel pressure and electrical circuits is advised.

Resetting the inertia switch (if equipped)

Some Ford models use an inertia switch to shut off power to the fuel pump after a crash or sharp impact. If your vehicle has one, follow these steps to reset it. The exact location can vary by year and model, so consult the owner's manual if you cannot locate the switch.

1. Turn off the ignition and remove the key.


2. Find the red reset button—commonly in the trunk, near the spare tire well, or under the driver's side dash. If the button is popped out, push it back in firmly to reset.


3. Inspect the area for any obvious damage and reconnect any wiring that may have been disturbed. If a fuse was blown, replace it with one of the same rating.


4. Close the trunk or dash area, then turn the ignition to ON for 2–3 seconds, OFF for 2–3 seconds. Repeat this cycle 2–3 times to help prime the fuel system.


5. Attempt to start the engine. If it starts and runs smoothly, the reset may be complete. If not, proceed with the remaining checks or seek service.

Not all Ford models have an inertia switch, and some switch locations differ. Always refer to the vehicle’s manual for exact instructions and location.

Check the fuel pump fuse and relay

Electrical protection and control components—the fuse and relay—play a critical role in delivering power to the pump. Here’s how to verify them:

• Locate the fuse box (engine bay or cabin) and identify the fuel pump fuse. Use the diagram on the cover or in the manual to confirm the correct fuse.


• Inspect the fuse: if it’s blown, replace it with a fuse of the same amperage rating. Do not substitute a higher rating.


• If a spare fuse is available, test by swapping the fuel pump relay with a similar, known-good relay (e.g., a cooling fan or horn relay) to see if the pump runs.


• Check the relay socket for signs of corrosion or a loose connection. Clean or reseat the relay if needed.

After replacing fuses or relays, attempt to start the vehicle to determine whether power is reaching the pump. If the pump still does not run, there may be an issue with wiring or the pump itself, requiring further testing.

Priming the fuel system and ignition cycling

On many Ford models, cycling the ignition helps re-energize the fuel rail and prime the system. Use this method if recommended by your manual or dealer guidance.

1. Turn the ignition to the ON position (do not start the engine) and wait about 2–3 seconds for the pump to prime. You may hear a faint whir or hum from the rear of the vehicle as the pressure builds.


2. Turn the key to OFF for a couple of seconds, then back to ON for another 2–3 seconds. Repeat this cycle 3–5 times.


3. Try to start the engine. If it starts, let it run at a low idle to build steady fuel pressure. If it stalls or fails to start after multiple cycles, move on to fuel-pressure testing or professional diagnosis.

Note: Do not crank the engine continuously for long periods while attempting toprime the system; prolonged cranking without fuel pressure can flood the engine or damage components.

Testing fuel pressure and diagnosing the pump

If basic resets don’t restore operation, you’ll want to test the actual fuel pressure and observe electrical current to the pump. This requires a fuel pressure gauge and may require access to the service manual for your exact engine variant.

• Relieve fuel system pressure before disconnecting lines. This is typically done by pulling the fuel pump fuse and cranking the engine until it stalls.


• Connect a fuel pressure gauge to the test port on the fuel rail or Schrader valve if your engine has one. Watch the gauge while the engine is cranked or while the ignition is in the ON position.


• Compare the measured pressure to the manufacturer’s specification for your engine. If pressure is too low or drops quickly, the pump, fuel pressure regulator, or leaks in the line may be at fault.


• Check electrical power to the pump while the engine is cranked. If the pump isn’t receiving power, investigate wiring, connectors, fuses, and the fuel pump relay rather than assuming a bad pump.

Fuel-system testing can vary by model and year; use the service manual or a qualified technician to interpret readings and perform safe pressure tests.

After you’ve completed resets or replacements

Once the fuel pump system is functioning again, take these follow-up steps to ensure reliability and roadworthiness:

• Clear any stored fault codes with an OBD-II scanner if you had a check engine light or fault codes related to the fuel system.


• Take a short test drive in a safe area to verify consistent starting, smooth idle, and stable acceleration without stalling.


• Monitor for any unusual symptoms (hesitation, misfires, or fuel odor) that could indicate a lingering issue in the fuel delivery or return system.

If problems recur, or you cannot locate the relevant components, seek professional service. A trained technician can perform advanced diagnostics, including fuel-pressure decay tests and injector/ECU checks, to pinpoint the root cause.

Model-specific notes for Ford owners

Ford vehicles span many generations, and not every model uses the same reset process. Some newer vehicles rely more on software control and onboard diagnostics than on a physical reset button. Always consult your owner’s manual for exact locations, and consider calling a dealer or independent shop if you’re unsure about the correct procedure for your model and year.

Summary

Resetting a Ford fuel pump is not a single universal action. Start with the simplest checks: inertia switch (if equipped), fuse and relay status, and ignition cycling to prime the system. If these steps don’t restore operation, verify fuel pressure with the proper tools and inspect electrical wiring. For persistent failures, the pump itself or its control circuitry may need professional diagnosis or replacement. Always prioritize safety and refer to your model’s manual for model-specific instructions.

How do you reset a fuel pump control module?

To reset a fuel pump control module, first check for a fuel pump shut-off switch (also called an inertia switch), often in the passenger footwell, and press the reset button on it. If the module was replaced, it likely needs professional programming to sync with the vehicle's computer, as simply pressing the inertia switch will not reset a new or failed module. 
Method 1: Resetting the inertia switch
This applies if the pump stopped working due to a physical impact, like a minor accident. 

1. Turn off the ignition. 
2. Locate the inertia switch. It is commonly found in the passenger footwell, sometimes behind the glove box, or in the trunk on the driver's side. 
3. Press the reset button. Push the button on top of the switch until you hear a click. This reactivates the fuel pump circuit. 
4. Check for fuel leaks: and repair them if any are found before driving. 
5. Start the engine: and check if the fuel pump is working.

Method 2: Programming a new or replaced module
This method is for when you have replaced the fuel pump control module itself and the vehicle will not start. 

1. Professional programming is required. A new module must be synchronized with the vehicle's computer (often the Body Control Module or BCM). 
2. Use specialized tools. This process requires a professional scan tool, a laptop, specific software, and often an online subscription to the manufacturer's service system. 
3. Visit a professional. The easiest and most reliable way to get this done is to take the vehicle to a dealership or a certified mechanic with the correct diagnostic equipment to perform the programming procedure.

Other troubleshooting steps

• Check fuses and relays: Inspect the fuel pump fuse and relay for a blown connection. 
• Battery reset: In some cases, disconnecting the battery terminals for a short period can reset some vehicle systems. However, this is not a substitute for professional programming for a new module and may not solve the problem if there is a hardware failure. 

Where is the fuel reset button on a Ford F-150?

For an older Ford F-150 (generally pre-2009), the fuel pump reset switch is a safety feature usually found on the passenger side footwell behind the kick panel, with a red button on top that you press to reset after an impact. For modern F-150s (generally 2009 and newer), there is no manual switch; the vehicle's restraint control module (airbag module) controls the fuel pump, and you may need to restart the engine a couple of times after a collision to reset it.

1. Locate the switch: Look in the passenger side footwell, behind the kick panel (the panel at the bottom of the dashboard) to the left of the fuse box. 
2. Turn off the ignition: Ensure the key is in the off position. 
3. Check for leaks: Before resetting, inspect the fuel system for any leaks. 
4. Press the reset button: Push down firmly on the red button on top of the inertia switch until you hear a click. The switch is in the "down" or "on" position when reset and the "up" or "tripped" position when the button is raised. 
5. Verify the reset: Turn the ignition to the "on" position, wait a few seconds, then turn it back to "off" and re-check for leaks. 

For newer F-150s (2009 and newer)

1. Inspect for damage: After a collision, first inspect the vehicle for any visible damage and confirm there are no fuel leaks. Have the fuel system inspected by a professional if needed. 
2. Use the ignition: With the key in the ignition, turn it to the "start" position, then turn it off. 
3. Restart the engine: Turn the key to the "on" position again to restart the engine. You may need to repeat these steps a couple of times. 
4. If you have a push-button start: Press the start button twice without your foot on the brake to cycle the ignition and reactivate the fuel system. 

Important considerations

• Modern vehicles: Models from 2009 onward no longer have the manually resettable inertia switch. Instead, the restraint control module monitors impact and controls power to the fuel pump. 
• Warning signs: If the engine cranks but won't start after a minor collision or hitting a large pothole, it could indicate the fuel pump shut-off has been triggered. 
• Professional inspection: Ford recommends having a dealer inspect the vehicle's fuel system after any collision. 
• Check fuses: If resetting the switch doesn't work, check the fuel pump fuse or relay in the fuse box under the hood. 

Where is the fuel pump reset switch located?

The fuel pump shut-off switch, also known as an inertia switch, is commonly located in the passenger side front footwell, often behind a kick panel or an access panel. Its exact location can vary by vehicle, so check the driver's side footwell for older models, behind the glove box, or in the luggage or trunk area, especially in SUVs. The switch is identifiable by a red button on top and is reset by pushing it until it clicks.

General location

• Passenger side footwell: This is the most common location for many vehicles, especially newer models. You may need to remove a plastic kick panel or other access cover to see it. 
• Driver's side footwell: In some older vehicles, like certain Ford F-150s from 1990-1991, the switch is located on the driver's side. 
• Behind the glove box: Some models may have the switch located under the glove box. 
• Luggage or trunk area: In SUVs and some other vehicles, you may find the switch in a compartment in the rear, such as on the driver's or passenger's side quarter panel. 
• Check the owner's manual: If you can't find it, the owner's manual will have the precise location for your specific vehicle.
