Fuel Pump 2013 Dodge Charger: Diagnosis, Replacement, and Cost Guide

The fuel pump in your 2013 Dodge Charger is a critical component, and when it fails, your car won't run. Recognizing early symptoms like engine sputtering, loss of power, or hard starting can prevent a complete breakdown. Replacing a failing fuel pump typically costs between $650 and $950 for parts and labor, though DIY replacement is possible for experienced individuals. This comprehensive guide details everything you need to know about diagnosis, repair, maintenance, and costs specific to the 2013 Charger.

Understanding the Fuel Pump in Your 2013 Dodge Charger
The electric fuel pump is located inside the fuel tank. Its primary function is to deliver pressurized gasoline from the tank to the engine’s fuel injectors at the precise pressure required for combustion. The 2013 Charger typically uses a high-pressure pump designed for its specific engine requirements. Without this constant flow of pressurized fuel, the engine will not start or run. The pump is integrated into the fuel pump module assembly, which often includes the fuel level sending unit, fuel filter sock, and pressure regulator. Fuel pump operation is controlled by the vehicle's Powertrain Control Module.

Common Symptoms of a Failing Fuel Pump in a 2013 Dodge Charger
Ignoring these signs risks leaving you stranded:

  1. Engine Cranks But Won’t Start: The most classic symptom. The starter turns the engine over normally, but no fuel reaches the cylinders.
  2. Loss of Power During Acceleration or Under Load: The engine struggles or sputters when pressing the accelerator, climbing hills, or carrying heavy loads due to inadequate fuel pressure.
  3. Engine Sputtering or Surging at High Speeds: Consistent operation falters as demand increases, causing noticeable hesitation or sudden bursts of speed.
  4. Engine Stalling Unexpectedly: Complete fuel interruption causes the engine to shut down, often restarting after cooling down temporarily.
  5. Whining or Humming Noise From the Fuel Tank: A loud, abnormal noise coming from the rear seats or trunk area can indicate a worn pump motor struggling.
  6. Difficulty Starting When Warm: The pump overheats internally, reducing pressure only when hot.
  7. Reduced Fuel Mileage: While less common initially, a failing pump can disrupt the air/fuel ratio.
  8. Check Engine Light with Fuel-Related Codes: Codes like P0087 (Fuel Rail/System Pressure Too Low), P0190 (Fuel Rail Pressure Sensor Circuit), or P0230 (Fuel Pump Primary Circuit) point towards pump or circuit issues.

How to Diagnose Fuel Pump Issues in Your 2013 Dodge Charger
Proper diagnosis prevents unnecessary replacements:

  1. Listen for Initialization: Turn the ignition key to "ON" (without starting). A faint whirring sound from the rear should last 2-3 seconds as the pump primes the system.
  2. Check Fuel Pump Relay and Fuse: Locate the Power Distribution Center (fuse box) under the hood. Consult the owner's manual diagram. Swap the fuel pump relay with a known good identical relay (like the horn relay). Replace the fuel pump fuse if blown (typically 15A or 20A).
  3. Perform a Fuel Pressure Test: Rent a fuel pressure test kit. Locate the Schrader valve on the fuel rail. Connect the gauge, turn the key to "ON," and compare the reading to factory specification (usually 55-65 PSI for most 2013 Charger engines). Low pressure confirms a pump or regulation issue.
  4. Check Voltage at the Pump Connector: Access the electrical connector near the fuel tank. Backprobe with a multimeter set to DC Volts. An assistant turning the key to "ON" should show battery voltage (approx. 12V) for 2-3 seconds. Consistent voltage means the circuit is good; absence points to wiring or control problems.
  5. Inspect for Physical Damage: Look for signs of leaks, damaged wiring, or severe corrosion at connectors near the tank.
  6. Rule Out Contaminated Fuel: Bad gas or excessive debris can accelerate pump failure. Consider fuel quality and tank contamination if diagnosis is unclear.

Causes of Fuel Pump Failure in a 2013 Dodge Charger
Understanding why pumps fail helps prevention:

  1. Running the Tank Consistently Low: Fuel cools and lubricates the pump motor. Repeatedly driving on "E" causes overheating and wear.
  2. Contaminated Fuel: Dirt, rust, or debris entering the tank clogs the pump's intake filter sock and strains the motor.
  3. Electrical Issues: Voltage spikes, corroded connectors, damaged wiring, or failing relays put undue stress on the pump motor.
  4. Natural Wear and Tear: Like any electromechanical device, internal components wear out after many miles. Pumps typically last 100,000-150,000 miles.
  5. Fuel Overheating: Extended idling in hot weather or heat soak can degrade fuel and affect pump performance.
  6. Faulty Installations: Improper handling or installation during previous work can damage the pump or its seals.

Step-by-Step Guide to Replacing the Fuel Pump in a 2013 Dodge Charger
Warning: This involves fuel vapors. Work in a well-ventilated area away from sparks or flames. Depressurize the system before starting. DIY requires mechanical skill.

  1. Depressurize the System: Locate the fuel pump fuse or relay in the PDC. Start the engine and let it stall. Crank for an additional 5 seconds to purge residual pressure.
  2. Disconnect Battery: Always disconnect the negative battery terminal for safety.
  3. Access the Fuel Pump Module: Move rear seat cushions. Locate the fuel pump access panel under the carpet in the rear seat well. (Some models may require partial tank lowering).
  4. Disconnect Electrical and Fuel Lines: Unplug the wiring harness connector. Depress the release tabs on the quick-connect fuel lines using proper disconnect tools. Wrap fittings in clean cloths.
