Dodge Charger Fuel Pump Reset Button: A Complete Guide to Resetting Your Fuel Pump

If your Dodge Charger won’t start, stalls while driving, or hesitates during acceleration, the fuel pump may have triggered a safety shutdown. The quickest fix is to locate and reset the Dodge Charger fuel pump reset button or perform a manual reset procedure. Most Dodge Charger models from 2006 to 2015 are equipped with an inertia switch or a fuel pump reset button that cuts power to the pump after a collision or electrical fault. Pressing this button restores fuel flow and gets your car running again in under five minutes. If your model lacks a dedicated reset button, you can reset the system by disconnecting the battery, pulling the fuel pump fuse, or using an OBD-II scan tool. This guide covers every method step by step, helping you diagnose and fix the problem without a trip to the mechanic.

What Is the Dodge Charger Fuel Pump Reset Button?

The fuel pump reset button is a safety device built into many Dodge Charger models. It acts as an inertia switch that automatically shuts off the fuel pump when the vehicle experiences a sudden impact or severe jolt. This prevents fuel from continuing to flow in the event of an accident, reducing the risk of fire or fuel leaks.

Some Dodge Charger models feature a dedicated fuel pump reset button, a handy mechanism designed to safeguard the vehicle's electrical system during accidents or severe impacts. This button, when triggered, interrupts the fuel pump's operation to prevent potential hazards like fuel leaks or fires.

Not every Dodge Charger has a physical reset button. If your vehicle lacks this button, the fuel pump's operation is managed solely through the vehicle's electrical system, and resets may require more involved procedures.

Where Is the Dodge Charger Fuel Pump Reset Button Located?

The location of the reset button varies by model year and trim. Here are the most common places to check:

For 2006–2010 Dodge Charger models:

  • Look in the trunk, on the driver’s side behind the carpeted panel. The button is usually a small, red or yellow rectangular switch mounted near the fuel pump access panel.
  • Some models have the reset button near the fuel pump itself, often in the rear of the vehicle, typically accessible by removing a panel in the trunk or lifting the rear seat, depending on the model year. Once you’ve located the pump, look for a small, often red or yellow button nearby.

For 2011–2015 Dodge Charger models:

  • The reset button may be located on the center console. For the 2015 Dodge Charger, press and hold the Override (OVRD) button located on the center console for five seconds to reset the fuel pump.

For models without a physical reset button:

  • The 2009 Dodge Charger uses an electronic control module (ECM) to manage fuel pump operation rather than a physical button. Resetting is done through the ignition key or by disconnecting the battery.

If you cannot find the button, check your owner’s manual for the exact location. The button is usually brightly colored or labeled for easy identification.

How to Reset the Fuel Pump on a Dodge Charger: Step-by-Step Methods

There are several ways to reset the fuel pump on a Dodge Charger. Choose the method that matches your model and tools.

Method 1: Using the Fuel Pump Reset Button (If Equipped)

This is the simplest method and works when your Charger has a physical inertia switch.

  1. Turn off the engine and remove the key from the ignition.
  2. Locate the reset button in the trunk, near the fuel pump, or on the center console.
  3. Inspect the button. If the button is popped out, it indicates that the fuel pump has been deactivated. This is a safety feature, not a malfunction, and requires manual resetting to restore fuel pump operation.
  4. Press the button firmly until it clicks back into place, ensuring it’s fully seated.
  5. Turn the ignition to the ON position (do not start the engine). Listen for a faint buzzing sound from the fuel tank. That means the pump is priming.
  6. Start the engine. If the car fires up smoothly, the reset worked.
  7. Test drive. Drive for at least ten minutes under varied conditions. Watch for any warning lights or loss of power. If problems reappear, it’s time to have a professional run a diagnostic.

After resetting, if the button pops out again or the engine fails to start, this could signal a deeper issue, such as a faulty fuel pump or persistent electrical problem. In such cases, consult a professional mechanic.

Method 2: Disconnecting the Battery

This method works on most Dodge Charger models, including the 2009 version, and forces a full system reset.

  1. Turn off the vehicle and remove the keys from the ignition.
  2. Open the hood and locate the battery.
  3. Disconnect the negative terminal first using a wrench. Always disconnect the negative terminal first to reduce the risk of short circuits.
  4. Disconnect the positive terminal once the negative is removed.
  5. Wait at least 5 to 10 minutes to allow the system to fully discharge. This pause ensures that the fuel pump’s control module clears any fault codes and resets its internal memory.
  6. Reconnect the battery in reverse order: positive first, then negative.
  7. Turn the ignition to the ON position and listen for the fuel pump priming sound.
  8. Start the engine and test.

The most common way to reset a fuel pump on a 2009 Dodge Charger is by disconnecting the battery for 30 seconds, then reconnecting it again. This should reset the pump and allow it to begin functioning normally again.

Method 3: Removing the Fuel Pump Fuse or Relay

This method is effective when you do not have a reset button or want to avoid disconnecting the battery.

  1. Locate the fuse box. It is usually under the hood or inside the cabin. Check your owner’s manual for the exact location.
  2. Find the fuel pump fuse or relay. Look for labels like “Fuel Pump,” “FP,” or “EFI” (Electronic Fuel Injection). The fuel pump fuse is usually rated between 15 and 30 amps.
  3. Remove the fuse or relay using a fuse puller or needle-nose pliers. Inspect the fuse for damage. If the wire inside appears broken or melted, replace it with one of the same amperage rating.
  4. Wait 5 to 10 minutes to let the system fully discharge.
  5. Reinstall the fuse or relay securely in its original position.
  6. Turn the ignition to the ON position and listen for the pump priming.
  7. Start the engine and test.

If the new fuse blows immediately after replacement, it’s a sign of a deeper issue, such as a short circuit or a failing fuel pump. In such cases, further diagnosis by a professional mechanic is warranted.

Method 4: Using an OBD-II Scan Tool

This method is ideal for persistent issues that manual resets cannot resolve. It is precise and effective for clearing fault codes stored in the fuel pump control module.

  1. Ensure your scan tool is compatible with your Dodge Charger’s make and model, typically supporting OBD-II protocols.
  2. Connect the scan tool to the OBD-II port, usually located under the dashboard on the driver’s side.
  3. Power on the scan tool and select the option to communicate with the vehicle’s modules.
  4. Navigate to the fuel pump control module or powertrain control module (PCM), depending on your scanner’s interface.
  5. Look for the option to clear fault codes or reset the module, which effectively reinitializes the fuel pump system.
  6. After performing the reset, start the engine and monitor for any recurring issues. This will help determine if the problem has been resolved or if further diagnostics are needed.

A key advantage of using a scan tool is its ability to provide detailed diagnostic information. Before resetting, review any stored fault codes related to the fuel system. Codes such as P0087 (Fuel Rail/System Pressure – Too Low) or P0191 (Fuel Rail Pressure Sensor Circuit Range/Performance) can offer insights into the root cause of the issue. Addressing these underlying problems ensures the reset is not just a temporary fix but a long-term solution.

Common Symptoms of a Bad Fuel Pump in a Dodge Charger

Before you reset the fuel pump, make sure the pump is actually the problem. Here are the most common symptoms of a failing fuel pump in a Dodge Charger:

  1. Difficulty starting the vehicle. The engine may crank over but fail to start, or it may start with hesitation or stumbling. This is because the fuel pump is unable to deliver sufficient pressure to the fuel injectors, causing a shortage of fuel in the engine.
  2. Stalling and hesitation during acceleration. A faulty fuel pump can cause the engine to stall or hesitate during acceleration because the pump cannot provide enough fuel to meet the increased demand.
  3. Surging or jerking. This is caused by intermittent fuel delivery, which can lead to fluctuations in engine speed and power. The vehicle may feel like it is lurching or jumping as it drives.
  4. Reduced engine performance. The engine may run rough, idle poorly, or have difficulty maintaining a constant speed.
  5. Unusual noises. A faulty fuel pump may produce whining, buzzing, or humming sounds caused by worn or damaged components within the fuel pump.
  6. Check engine light. A faulty fuel pump can trigger the check engine light on your dashboard.

When to Call a Professional

If the reset does not work, or if any of these conditions apply, you should have a mechanic inspect your vehicle:

  • The check engine light stays on after a reset.
  • You notice a slow-fill fuel pump sound, which may indicate the pump is failing.
  • The fuel pump reset button pops out again immediately after you press it.
  • You smell fuel or see fuel leaks under the car.
  • The engine still stalls or hesitates after multiple reset attempts.

A mechanic can run a pressure test and replace the pump if needed. The fuel pressure on a Dodge Charger should be 49 psi. If there is no pressure, the problem is likely the pump, relay, or wiring.

Upgrading Your Dodge Charger with a Reliable Fuel Pump

If you have tried resetting the fuel pump multiple times and the problem persists, the pump itself may be worn out or failing. A replacement is often the most reliable long-term solution.
