Diagnosing, Replacing, and Maintaining Your 2019 Dodge Charger Fuel Pump

A failing or failed fuel pump is a top cause of a 2019 Dodge Charger refusing to start or experiencing severe performance issues. Understanding this critical component is essential for every Charger owner. This guide provides practical information on recognizing problems, replacement options, costs, and preventive maintenance specific to the 2019 Dodge Charger fuel pump system.

The fuel pump is the heart of your Charger's fuel delivery system. Located inside the fuel tank, its sole job is to pull gasoline from the tank and push it under consistent high pressure to the fuel injectors in the engine. The engine control computer precisely meters the fuel delivered by the injectors. Without the fuel pump supplying the correct pressure, your Charger cannot run. Symptoms of a failing pump can appear gradually or suddenly, leading to complete failure.

Recognizing Symptoms of a 2019 Dodge Charger Fuel Pump Problem

Ignoring early signs of fuel pump trouble often leads to being stranded. Pay close attention to these common indicators:

1. Failure to Start: This is the most frequent result of complete pump failure. Turning the key results in the engine cranking normally but failing to catch and start. You may hear no sound from the pump priming when you first turn the key to the "ON" position before cranking.
2. Engine Sputtering or Stalling (Especially Under Load): A weakening pump struggles to maintain pressure when demand increases. Accelerating hard, going uphill, or carrying extra weight can cause the engine to stumble, jerk, or suddenly shut off without warning.
3. Loss of Power During Acceleration: You press the accelerator, but the Charger feels sluggish and unresponsive, lacking its usual power. Engine RPMs may climb very slowly.
4. Engine Surging at Constant Speed: On the highway or cruising at a steady RPM, the engine may unpredictably gain and lose speed as if you were lightly tapping the gas pedal. This is due to inconsistent fuel pressure.
5. Whining or Humming Noise from the Fuel Tank: A loud, high-pitched whining or buzzing sound coming from the rear of the car, especially near the fuel tank, that is louder than normal is a classic sign of a failing pump.
6. Difficulty Starting After Vehicle Sits: If the car starts fine when cold but has significant trouble restarting after being driven and parked for a short period (like at a store), it can indicate a pump struggling when warm.
7. Check Engine Light with Fuel-Related Codes: While the fuel pump itself rarely triggers a specific code, associated pressure problems often set codes like P0087 (Fuel Rail/System Pressure Too Low), P0171 (System Too Lean Bank 1), or P0174 (System Too Lean Bank 2).

Diagnosing a Suspected Fuel Pump Issue in a 2019 Dodge Charger

Before condemning the fuel pump, performing basic checks is crucial to avoid unnecessary expense.

1. Listen for Prime: When you first turn the ignition key to "ON" (without cranking the engine), you should hear a distinct humming sound from the rear of the car for 2-3 seconds. This is the pump priming the system. Silence indicates a power problem or a dead pump.
2. Check Fuel Level: Always verify the fuel gauge is working and you actually have adequate fuel. Running consistently low on fuel overheats and prematurely wears the pump.
3. Check Fuel Pressure: This is the most definitive test. You need a fuel pressure gauge kit designed for modern high-pressure systems. Locate the Schrader valve test port on the fuel rail. Attach the gauge, turn the key to "ON" (pump should prime and build pressure), and check if pressure meets specifications (typically around 55-65 PSI for most 2019 Charger engines at prime). Then, with the engine running (if possible), verify pressure remains stable, especially under load.
4. Check Fuel Pump Fuse and Relay: Locate the Charger's under-hood fuse box. Consult your owner's manual or the fuse box diagram lid. Identify the fuse dedicated to the fuel pump. Remove it and inspect the metal strip inside for breaks. Using a multimeter, test for continuity. Also, locate the fuel pump relay. Swap it with an identical relay (like the horn relay) and see if the problem changes. A faulty relay is a common cause of no pump operation.
5. Inspect Wiring: Visually inspect the wiring harness going to the fuel pump access panel for any obvious damage, chafing, or corrosion. Check connections at the relay and fuse box.

Replacing the 2019 Dodge Charger Fuel Pump: Steps and Options

If diagnosis points to a failed pump, replacement is necessary. Access is gained through the trunk/cargo area floor.

Pre-Work Safety Requirements:

• WORK IN A WELL-VENTILATED AREA: Gasoline fumes are extremely flammable. Avoid sparks, open flames, or smoking nearby.
• DEPRESSURIZE THE FUEL SYSTEM:
  • Locate the fuel pump relay in the under-hood fuse box.
  • Start the engine and let it idle.
  • Carefully remove the fuel pump relay. The engine will stall within a few seconds as fuel pressure depletes.
  • Attempt to restart the engine briefly to ensure all pressure is released (it won't start).
• DISCONNECT THE BATTERY: Disconnect the negative battery terminal before any electrical work near the fuel system.
• HAVE A FIRE EXTINGUISHER READY: Always practice safety.

Replacement Procedure Overview (General - Specific steps vary):

1. Access the Fuel Pump Module: Clear all items from the trunk. Remove the trunk liner/carpet. Locate the round or rectangular access panel in the floor directly above the fuel tank/pump. Remove the screws or bolts securing the panel.
2. Disconnect Electrical and Fuel Lines: Under the access panel, you'll see the pump module's locking ring, electrical connector, and fuel line connections. Carefully disconnect the electrical connector. Release the locking tabs on the fuel feed and return lines (if equipped) using special disconnect tools or a careful flat-head screwdriver. Avoid damaging the plastic lines.
3. Remove the Locking Ring: Use a large flat-head screwdriver and a hammer to gently tap the locking ring counter-clockwise (it's reverse threaded in many cases). Be careful not to damage the ring or tank flange. Lift the ring off.
4. Remove the Fuel Pump Module: Carefully lift the pump assembly straight up and out of the tank. Tip it slightly as you lift to clear the float arm. Some fuel may spill. Have rags ready.
5. Transfer Components (if necessary): If your new pump doesn't come as a complete assembly module, you must transfer the pump itself, level sender, filter sock, etc., from the old module housing to the new one EXACTLY as they were. This is complex and error-prone; a complete module assembly is highly recommended.
6. Install the New Module: Clean the sealing surface on the fuel tank flange. Install a NEW locking ring gasket onto the module (often pre-installed on assembly). Carefully lower the new module assembly into the tank, aligning it with the locating notches. Ensure the fuel float arm moves freely.
7. Secure Locking Ring: Place the locking ring onto the module flange and turn it clockwise until it is fully seated and tight. Tap gently with a hammer and punch if needed.
8. Reconnect Fuel Lines and Electrical: Push the fuel lines back onto their connectors until you hear/feel a distinct click. Ensure they are fully locked. Reconnect the electrical connector.
9. Reinstall Access Panel: Place the panel back, reinstall and tighten screws/bolts securely.
10. Reconnect Battery: Reattach the negative battery cable.
11. Test for Leaks: Turn the ignition key to "ON" (do not start) several times. The pump will prime. Listen for pump operation. Visually inspect the connections under the access panel for any fuel leaks. If leaks are found, shut off ignition, disconnect battery, and re-secure connections.
12. Start Engine: Attempt to start the engine. It may crank slightly longer the first time as pressure builds. Verify smooth idle and proper operation.

Choosing the Right Fuel Pump for Your 2019 Dodge Charger

Selecting a quality replacement is critical for longevity and performance:

1. OEM (Mopar): The factory pump from Dodge. Ensures perfect compatibility and fitment. Highest cost, but ideal for reliability and peace of mind.
2. Premium Aftermarket (e.g., Bosch, Delphi, Denso, Carter): High-quality brands meeting or exceeding OEM specifications. Often a better value than Mopar while maintaining reliability and fitment. Bosch is often an OEM supplier. Check model compatibility carefully.
3. Economy Aftermarket: Less expensive options. While some may work fine, quality control varies significantly. They are more prone to premature failure and may not deliver the exact pressure required. Only recommended for very tight budgets with an eye on short-term ownership.
4. Complete Module vs. Pump Only:
   • Complete Module: Includes the pump, fuel level sender, reservoir bucket, filter sock, wiring, and module housing as a complete assembly. This is the BEST choice. It eliminates complex transfer of parts, ensures all critical components are new, and guarantees fitment. Highly recommended for DIYers and professionals.
   • Pump Only: Only the electric pump motor unit. You must disassemble the old module housing, transfer the pump, fuel level sender (a common point of failure itself), filter sock, and other components to the new pump. This is time-consuming, requires meticulous care, and relies on the old sender and housing which may be worn. Mistakes lead to leaks, inoperative fuel gauges, or poor pump performance. Not recommended unless you are highly experienced.

• Dealership Total Cost: Dealerships will use Mopar parts and have the highest labor rates ($140-$200/hr). Total cost often exceeds $1,000,sometimesreaching$1,500+.

Preventing Premature 2019 Dodge Charger Fuel Pump Failure

Fuel pumps typically last over 100,000 miles with proper care. Extend the life of yours:

1. Never Run the Tank Dry: This is the #1 cause of premature failure. Running low consistently forces the pump to work harder to pick up fuel from the bottom of the tank. More critically, fuel acts as a coolant and lubricant for the pump motor. Running low or dry causes overheating and immediate damage. Keep the tank above 1/4 full whenever possible.
2. Use Quality Fuel: Purchase gasoline from reputable stations with high turnover. Contaminated or very old gas (varnish, water) can damage the pump and injectors. Avoid questionable discount stations.
3. Replace the Fuel Filter (If Applicable): While many modern cars have "lifetime" filters integrated with the pump module, some earlier models or trims might have an external filter. If yours does, replace it according to the Charger's maintenance schedule to prevent restricted flow stressing the pump.
4. Avoid Fuel Additives Unless Necessary: Many additives offer dubious benefits and some can damage pump seals or components if overused. Stick to a quality detergent gasoline (Top Tier) and avoid frequent additive treatments.

When to Seek Professional Help for Fuel Pump Issues

While the replacement process is feasible for DIYers with proper tools and safety precautions, consider a professional in these situations:

• You are uncomfortable with the significant safety risks of working with gasoline.
• Diagnosis is unclear (you don't have access to a fuel pressure gauge).
• You lack the specific tools required for fuel line disconnects or accessing the pump.
• The wiring appears damaged or corroded, requiring expert diagnosis/repair.
• The vehicle shows symptoms but a confirmed pump pressure test shows the correct pressure, indicating a more complex issue requiring diagnostics.
• You opt for a pump-only replacement and need the level sender calibrated or transferred correctly.

A compromised 2019 Dodge Charger fuel pump disrupts drivability and can leave you immobile. Prompt attention to symptoms and proper diagnosis are crucial. Replacement involves tank access but following safety protocols and choosing a quality complete module ensures a reliable fix. Maintaining adequate fuel levels is the most effective way to maximize fuel pump life. If in doubt, consult a qualified mechanic to accurately diagnose and efficiently resolve the problem.
