Fuel Pump Dodge Charger 2016: The Complete Guide to Symptoms, Replacement, and Cost

The bottom line: If your 2016 Dodge Charger is cranking but won't start, sputtering during acceleration, or making a loud whining noise from the rear of the car, the fuel pump is likely failing. Replacing it typically costs between $700 and $1,513 including parts and labor, depending on your engine type and whether you choose a professional shop or DIY route . The 2016 Charger uses a specific fuel pump module that varies by engine (3.6L V6, 5.7L Hemi, or 6.4L SRT) and even by trim level (SXT, R/T, Pursuit, etc.) . This guide covers everything you need to know—from symptoms and diagnosis to the replacement process, parts selection, and cost breakdown.

How to Tell If Your 2016 Dodge Charger Fuel Pump Is Failing

Your Charger's fuel pump is an electric motor inside the fuel tank that delivers gasoline from the tank to the engine at a specific pressure . When it starts to fail, you'll notice one or more of these clear warning signs:

1. Difficulty Starting or the Engine Won't Start
This is the most common symptom. The engine cranks over normally, but it takes longer than usual to fire up, or it cranks and never starts. A failing pump can't build enough fuel pressure to push fuel to the injectors .

2. Engine Sputtering or Stalling at High Temperatures
A weak fuel pump often fails when the engine is hot because heat increases electrical resistance. You might notice the engine sputtering, hesitating, or stalling entirely after driving for a while, especially on hot days .

3. Loss of Power Under Load (Acceleration or Hill Climbing)
If the pump can't deliver enough fuel volume, the engine will feel sluggish or lose power when you step on the gas, particularly when merging onto highways or climbing a steep grade .

4. Whining or Humming Noise from the Fuel Tank Area
A healthy fuel pump makes a quiet, brief hum when you turn the key to "ON" position. If you hear a loud, continuous whining, buzzing, or howling sound coming from the rear of the car (near the fuel tank), the pump bearings are worn out .

5. Check Engine Light Illuminates
A failing fuel pump can trigger diagnostic trouble codes (DTCs) related to fuel pressure or fuel system lean conditions. Common codes include P0087 (Fuel Rail/System Pressure Too Low) or P0171/P0174 (System Too Lean) .

6. Surging or Jerking During Steady Cruising
If the car suddenly surges forward or jerks while you're maintaining a constant speed, the fuel pump may be delivering inconsistent fuel pressure .

How to Diagnose a Bad Fuel Pump on a 2016 Dodge Charger

Before ordering a replacement part, confirm the pump is actually the problem. Here's a simple diagnostic process:

Step 1: Listen for the Prime
With the engine off, turn the key to the "ON" position (without starting). You should hear a 2-3 second hum from the rear of the car. If you hear nothing, the pump may not be getting power or may be dead .

Step 2: Check the Fuel Pump Fuse and Relay
Open the fuse box under the hood or in the trunk. Locate the fuel pump fuse and relay. If the fuse is blown, replace it with one of the same amperage. If the relay is faulty, swap it with a known good relay of the same type .

Step 3: Test Fuel Pressure
This is the most accurate way to diagnose. A mechanic will attach a fuel pressure gauge to the Schrader valve on the fuel rail. For a 2016 Charger, the fuel pressure should be between 50-60 PSI (depending on the engine). If pressure is below spec or drops quickly after the pump stops, the pump is bad .

Step 4: Check for Power and Ground at the Pump
If the fuse and relay are good, but the pump doesn't run, you need to verify that 12 volts and a good ground are reaching the pump connector. If power and ground are present, the pump itself is faulty .

Where Is the Fuel Pump Located on a 2016 Dodge Charger?

The fuel pump is inside the fuel tank. On the 2016 Dodge Charger, the tank is located under the rear of the vehicle. Accessing the pump typically requires:

  • Removing the rear seat (on some models, there is an access panel under the rear seat cushion)
  • Or lowering the fuel tank from underneath the car (required on many Charger models)

Some 2016 Charger models have a dual-pump setup (left and right side pumps) in the tank, especially on certain V8 configurations. You need to verify which side your car uses before ordering parts .

Fuel Pump Replacement Process for a 2016 Dodge Charger

Replacing the fuel pump is a moderate to difficult DIY job. Here is the step-by-step process, assuming you have mechanical experience and the right tools.

Step 1: Relieve Fuel System Pressure
Locate the fuel pump fuse or relay and remove it. Start the engine and let it run until it stalls. This releases the high pressure from the fuel lines. Crank the engine an additional 2-3 seconds to ensure all pressure is gone .

Step 2: Disconnect the Battery
Disconnect the negative battery terminal to prevent any electrical sparks or short circuits during the repair .

Step 3: Drain the Fuel Tank (or Siphon It)
Use a siphon pump or a professional fuel extraction tool to drain as much fuel as possible from the tank. A full tank is very heavy (over 100 pounds) and dangerous to handle .

Step 4: Access the Fuel Pump

  • If accessing through the rear seat: Remove the rear seat cushion by pulling up on the front edge. Remove the sound-deadening foam. You'll see a metal access cover. Remove the bolts and lift the cover .
  • If dropping the tank: Safely jack up the rear of the vehicle and support it with jack stands. Support the fuel tank with a floor jack and a block of wood. Remove the fuel tank retaining straps or bolts. Carefully lower the tank just enough to disconnect the filler tube, fuel lines, and electrical connectors. Then lower the tank completely .

Step 5: Remove the Old Fuel Pump
Once you have access to the pump module, disconnect the fuel lines (using a fuel line disconnect tool) and the electrical connector. Use a hammer and punch or a special tool to turn the retaining ring counterclockwise and remove it. Lift the pump module out of the tank carefully, being mindful of the fuel level float arm .

Step 6: Install the New Fuel Pump
Compare the new pump with the old one to ensure they match exactly. Transfer any reusable brackets or the fuel level float arm if they are not included with the new pump. Install a new O-ring gasket on the tank opening. Lower the new pump assembly into the tank, making sure the float arm is oriented correctly. Install and tighten the retaining ring .

Step 7: Reassemble Everything
Reinstall the fuel tank (if you dropped it) and tighten the retaining straps. Reconnect the fuel lines, electrical connectors, and filler tube. Reinstall the rear seat or access panel. Reconnect the battery negative terminal .

Step 8: Prime the System and Test for Leaks
Add at least 2-3 gallons of fuel to the tank. Turn the ignition to the "ON" position for 2-3 seconds, then off. Repeat this 3-4 times to prime the fuel system. Start the engine and check for any fuel leaks around the pump module and fuel lines. Let the engine run and verify the pressure is correct .

Choosing the Right Replacement Fuel Pump for Your 2016 Dodge Charger

Selecting the correct pump is critical for proper fit and performance. The 2016 Charger uses different pumps depending on the engine and trim.

1. Know Your Engine and Trim
The fuel pump must match your specific engine. The 3.6L Pentastar V6, 5.7L Hemi V8, and 6.4L SRT8 V8 all have different flow rate and pressure requirements . Even within the same engine, trim levels like SXT, R/T, Pursuit, and Enforcer can use different pumps .

2. OEM vs. Aftermarket

  • OEM Mopar parts: The safest choice. They guarantee perfect fit and original-grade components. The cost is higher, but you eliminate compatibility worries .
  • High-quality aftermarket brands: Brands like Delphi, Bosch, Spectra Premium, Denso, and Autopart Premium often manufacture pumps that meet or exceed OEM specifications. They offer good value and reliability .
  • Budget aftermarket parts: Cheap pumps (under $100) are notorious for premature failures, inaccurate fuel level senders, and poor fitment. They are generally not recommended for a job this involved .

3. Full Assembly vs. Pump Only
A "fuel pump module" typically refers to just the electric pump motor. A "full fuel pump assembly" includes the pump, fuel sending unit, fuel strainer/filter, and sometimes the fuel reservoir and float. Most experts recommend replacing the full assembly. This ensures comprehensive coverage and avoids having to access the tank again for a separate sender failure .

Tips to Extend the Life of Your New Fuel Pump

Once you've invested in a new fuel pump, follow these practices to maximize its lifespan and avoid premature failure:

1. Keep Your Tank at Least a Quarter Full
The fuel pump relies on the gasoline in the tank to stay cool and lubricated. Running the tank low frequently causes the pump to overheat, which shortens its life significantly .

2. Use High-Quality Fuel from Reputable Stations
Cheap or contaminated gasoline can introduce dirt, water, and debris into the fuel system, which clogs the pump strainer and damages the pump motor .

3. Replace Your Fuel Filter Regularly
If your vehicle has a separate inline fuel filter (check your owner's manual), replace it every 20,000 to 40,000 miles. A clogged filter forces the fuel pump to work harder, leading to early failure .

4. Address Electrical Issues Promptly
If you notice any warning signs like flickering dashboard lights, dimming headlights, or erratic fuel gauge readings, have the electrical system checked. Voltage drops or poor ground connections can damage the pump .

5. Avoid Running the Tank Completely Dry
Running out of fuel not only leaves you stranded, but it can also draw air into the pump, causing it to run without lubrication and potentially overheat or seize .

Final Thoughts

A failing fuel pump in your 2016 Dodge Charger is not something to ignore. The symptoms are clear, the causes are well understood, and the replacement process—while involved—is straightforward when handled by professionals or experienced DIYers.
