Fuel Pump for 2015 Chrysler 300: The Complete Guide to Replacement, Symptoms, and Costs

The bottom line: If your 2015 Chrysler 300 is experiencing hard starting, engine sputtering, loss of power during acceleration, or a whining noise coming from the fuel tank area, the fuel pump is likely failing. The fuel pump is located inside the fuel tank and must be replaced as a complete module assembly. Replacement costs typically range from $600 to $900 for parts and labor at a professional shop, but you can save significantly by purchasing a quality aftermarket unit and handling the installation yourself.

How the Fuel Pump Works on Your 2015 Chrysler 300

The fuel pump is an electric pump mounted inside the fuel tank. Its job is to draw fuel from the tank, pressurize it, and deliver it through the fuel supply lines to the engine's fuel injectors. The pump must maintain the correct pressure and volume to keep the engine running smoothly. On the 2015 Chrysler 300, the pump is part of a module assembly that also includes the fuel level sending unit, float, fuel pressure regulator, and strainer.

Your 2015 Chrysler 300 may have a 3.6L V6, 5.7L V8 HEMI, or 6.4L V8 SRT HEMI engine, and the fuel pump module is designed to fit all these engine options.

Common Symptoms of a Bad Fuel Pump

If your fuel pump is failing, you will notice one or more of the following symptoms:

  1. Engine won't start or is hard to start. This is the most common symptom. The pump can't build enough pressure to get fuel to the injectors.

  2. Engine sputtering or misfiring. When the pump delivers inconsistent fuel pressure, the engine may sputter, especially at highway speeds.

  3. Loss of power under stress. You may notice your car struggles to accelerate or loses power when climbing hills or carrying a heavy load.

  4. Whining noise from the fuel tank. A healthy fuel pump runs quietly. If you hear a loud whining or humming sound coming from the rear of the car, the pump is likely failing.

  5. Engine overheating. An underperforming fuel pump can cause the engine to run lean, which leads to higher operating temperatures.

  6. Check Engine Light. A drop in fuel pressure can trigger the check engine light to come on.

Confirming the Problem

Before you replace the fuel pump, make sure the pump is actually the issue. A clogged fuel filter or a bad electrical circuit can cause identical symptoms. A professional mechanic will perform a fuel pressure test to confirm the pump is delivering the correct pressure. On the 2015 Chrysler 300, the fuel pump should deliver around 55 to 60 psi at idle.

You can also check the fuel pump relay and fuses. The fuel pump relay is located in the front power distribution center under the hood. If the relay is faulty, the pump won't receive power.

Step-by-Step Replacement Guide

Replacing the fuel pump on a 2015 Chrysler 300 is a moderately difficult job. If you are not experienced with auto repair, it is highly recommended that you have a professional handle this job. Working with the fuel system is dangerous, and fuel vapors are highly flammable.

Safety precautions you must follow:

  • Disconnect the battery before starting any work.
  • Work in a well-ventilated area.
  • Wear safety goggles, gloves, and a respirator.
  • Have absorbent materials on hand to contain any fuel spills.
  • Do not smoke or allow any open flames near the work area.

The basic steps:

  1. Relieve fuel system pressure. Locate the fuel pump fuse in the trunk fuse panel and remove it. Then start the engine and let it run until it stalls. This relieves the pressure in the fuel lines.

  2. Disconnect the battery. Remove the negative battery cable to prevent any electrical sparks.

  3. Remove the back seat. The fuel pump access panel is located under the rear seat, behind the driver's side. Remove the rear seat cushion by pulling up on the front edge.

  4. Remove the access cover. You will see a metal cover plate. Remove the screws and lift the cover.

  5. Disconnect the fuel lines and electrical connector. Use a fuel line disconnect tool to release the quick-connect fittings. Then unplug the wiring harness.

  6. Remove the lock ring. Use a brass drift and a hammer to tap the lock ring counterclockwise. Never use steel tools on steel in this area, as sparks can ignite fuel vapors.

  7. Lift out the old pump module. Carefully remove the old pump assembly. Note the orientation of the float arm and the fuel lines.

  8. Install the new pump module. Transfer any reusable components from the old unit to the new one. Install the new pump, making sure the float arm and seal are properly positioned.

  9. Reinstall the lock ring. Tap it clockwise to secure the pump module.

  10. Reconnect everything. Reattach the fuel lines, electrical connector, and access cover. Reinstall the rear seat and reconnect the battery.

  11. Test the system. Turn the key to the "ON" position (without starting) to prime the fuel system. Check for leaks. Then start the engine and verify that it runs smoothly.

Replacement Cost

The cost to replace the fuel pump on a 2015 Chrysler 300 depends on whether you do it yourself or hire a professional.

  • DIY cost: $40 to $80 for the pump module (budget brand) up to $200 to $450 for a premium or OEM part.
  • Professional repair cost: The national average for fuel pump replacement on most vehicles is between $611 and $894, including parts and labor. In Dubai, the cost starts from AED 450.
  • Dealership cost: Expect to pay $600 to $1,000 or more, especially if you use OEM Mopar parts.

Additional Tips

  • Replace the fuel filter at the same time. If your 300 has an external fuel filter, replace it when you replace the pump. This ensures the new pump is protected from debris.
  • Replace the fuel pump relay. The relay is a common failure point on these vehicles. It's cheap insurance to replace it when you do the pump.
  • Keep the tank at least a quarter full. The fuel in the tank cools and lubricates the electric pump. Running the tank low frequently can shorten the life of your new pump.
  • Check for leaks after the repair. If you smell gasoline or see any leaks, do not start or drive the car. Have it towed to a shop for inspection.

Final Thoughts

If your 2015 Chrysler 300 is showing signs of a bad fuel pump, do not wait until it leaves you stranded. The symptoms are usually clear, and a fuel pressure test will confirm the diagnosis. Replacing the fuel pump module is a straightforward job if you have the right tools and follow safety precautions. Whether you choose an OEM Mopar part or a high-quality aftermarket unit like those from KEMSO, you can restore your car's performance and reliability.
