Fuel Pump 2010 Dodge Charger: Complete Guide to Diagnosis, Replacement, and Maintenance

The 2010 Dodge Charger uses a single in-tank electric fuel pump as part of a returnless fuel system. This pump is located inside the fuel tank and delivers pressurized fuel to the engine through the fuel lines. Whether you drive the V6 SXT model, the V8 R/T, or the high-performance SRT8, your Charger relies on just one fuel pump module to keep the engine running. Understanding how this component works, recognizing the warning signs of failure, and knowing what to do when it needs replacement can save you time, money, and frustration.

How the Fuel System Works in the 2010 Dodge Charger

The 2010 Charger uses a returnless fuel system, which means fuel flows from the tank to the engine, and unused fuel is not returned to the tank. This design improves efficiency and reduces evaporative emissions. The fuel pump module sits inside the fuel tank and contains several key components:

  • Electric fuel pump motor – pressurizes and delivers fuel
  • Fuel level sending unit – measures how much fuel is in the tank
  • Fuel strainer (sock) – filters debris before fuel enters the pump
  • Wiring harness and connectors – provide power and signal to the pump

The fuel pressure regulator is located in the engine bay, not inside the tank, which is typical for returnless systems.

How Many Fuel Pumps Does a 2010 Dodge Charger Have?

One. The standard configuration across all trims – including the SE, SXT, R/T, and SRT8 – uses a single in-tank fuel pump module. However, there is an important exception for certain models. Some R/T models with the 5.7L V8 engine may have an auxiliary electric pump as part of the fuel delivery system, particularly on vehicles equipped with a 19-gallon tank. This secondary pump is not a main fuel pump but rather a transfer unit that helps move fuel from one side of the saddle-style tank to the other.

Common Symptoms of a Failing Fuel Pump

If your fuel pump is starting to fail, you will likely notice one or more of these warning signs:

1. Hard Starting or Extended Cranking
When you turn the key, the engine takes longer than usual to start. This happens because the pump cannot build up enough fuel pressure quickly.

2. Engine Stalling
Your Charger may stall at idle, during acceleration, or while cruising. This is a clear sign that fuel delivery is inconsistent.

3. Loss of Power or Hesitation
You step on the gas, but the car feels sluggish or hesitates. This is especially noticeable when climbing hills or merging onto highways.

4. Whining Noise from the Fuel Tank
A healthy fuel pump runs quietly. If you hear a loud buzzing or whining sound coming from the rear of the car, the pump motor is likely worn out.

5. Engine Sputtering or Misfires
The engine may sputter, jerk, or misfire, especially at higher speeds. This occurs when the pump cannot maintain steady fuel pressure.

6. Check Engine Light
The onboard diagnostic system may set codes such as P0087 (fuel rail pressure too low), P0171 (system too lean), or P0230 (fuel pump primary circuit malfunction).

Diagnosing a Fuel Pump Problem

Before replacing the pump, you should perform a few basic checks to confirm the issue is actually the pump and not something else:

Step 1: Listen for the Prime Sound
Turn the ignition key to the ON position without starting the engine. You should hear a brief 1–2 second buzz coming from the rear of the car. This is the pump priming. No sound means the pump is not receiving power or has failed.

Step 2: Check the Fuel Pump Fuse and Relay
The fuel pump fuse is a 20-amp mini fuse located in the rear power distribution center. If the fuse is blown, check for a short circuit, damaged wiring, or a failing pump that draws excessive current. The relay should also be tested – a faulty relay will prevent power from reaching the pump.

Step 3: Test Fuel Pressure
Connect a fuel pressure gauge to the test port on the fuel rail. The 2010 Charger should produce approximately 58–62 psi at idle. Low pressure indicates a weak pump, a clogged filter, or a restriction in the fuel line.

Step 4: Inspect the Wiring and Connectors
Over time, the electrical connector at the pump can corrode or melt. A technical service bulletin (TSB 08-152-23) from FCA specifically addresses fuel pump connector issues on 2010 Chargers and recommends replacing the connector harness whenever the pump module is replaced.

What Causes Fuel Pump Failure?

Understanding the root causes of failure can help you prevent premature pump replacement:

Running on Low Fuel
The fuel in the tank acts as a coolant for the pump. When you consistently run the tank below a quarter full, the pump overheats and wears out faster. Keep the tank at least one-quarter full to extend pump life.

Contaminated Fuel
Dirt, rust, or water in the fuel can damage the pump internals and clog the strainer. Always buy fuel from reputable stations and consider using a fuel additive if you suspect contamination.

Clogged Fuel Filter
Some 2010 Charger models have an integrated filter inside the pump module. When the filter gets clogged, the pump must work harder, which increases heat and wear. Replace the filter as recommended in your owner's manual.

Electrical Issues
Corroded connectors, damaged wiring, or a failing relay can cause intermittent power loss to the pump, leading to premature failure.

Replacement Options: What You Need to Know

When the fuel pump fails, you have two main choices: replace just the pump motor or replace the entire pump module assembly.

Replace the Complete Assembly (Recommended)
Most mechanics and experts recommend replacing the entire fuel pump module assembly. This includes the pump, fuel level sending unit, strainer, and housing. The labor to access the pump is the same whether you replace just the pump or the whole assembly, so it makes sense to replace everything at once. A complete assembly costs between $200 and $600 depending on whether you choose aftermarket or OEM parts.

Pump-Only Replacement
Some aftermarket pumps allow you to replace just the motor cartridge. This is cheaper but carries risks – the old sending unit and strainer remain in service, and the housing may not seal properly. This approach is not recommended unless you are experienced with fuel system repairs.

Step-by-Step Replacement Guide

Replacing the fuel pump on a 2010 Dodge Charger is a moderately difficult job that requires patience and attention to safety. The fuel tank must be accessed from inside the vehicle.

Safety First

  • Work in a well-ventilated area away from sparks or open flames
  • Wear safety glasses and mechanic's gloves
  • Disconnect the negative battery terminal
  • Relieve fuel system pressure by removing the fuel pump relay, starting the engine, and letting it stall

Tools You Will Need

  • Socket set (metric, including deep sockets)
  • Ratchet with extensions
  • Jack and jack stands
  • Fuel line disconnect tools
  • Flathead screwdriver
  • Shop towels and absorbent pads
  • Approved gasoline container

Procedure

1. Remove the Rear Seat
The lower rear seat cushion lifts up and out. Locate the release clips along the front edge of the cushion, push down firmly, and lift toward the front of the car.

2. Access the Pump Module
You will see a metal cover plate on the floor pan. Remove the screws or bolts to expose the fuel pump module.

3. Disconnect Electrical and Fuel Lines
Carefully disconnect the electrical connector. Use the proper fuel line disconnect tools to release the quick-connect fittings. Have a rag ready to catch any residual fuel.

4. Remove the Locking Ring
Use a hammer and punch to rotate the locking ring counterclockwise. Lift the ring out, then carefully lift the pump module out of the tank.

5. Install the New Module
Transfer any necessary components from the old module to the new one, if required. Lower the new module into the tank, making sure the float arm is properly positioned. Install the locking ring and tighten it clockwise.

6. Reconnect Everything
Reconnect the fuel lines and electrical connector. Make sure the o-ring seal is properly seated to prevent leaks.

7. Test the System
Before reinstalling the seat, turn the ignition to ON and listen for the pump to prime. Check for fuel leaks at the connections. Start the engine and verify proper operation.
