2013 Dodge Avenger Fuel Pump: A Complete Guide to Symptoms, Replacement, and Cost

If your 2013 Dodge Avenger is having trouble starting, stalling, or making a whining noise from the rear of the car, the fuel pump is likely failing. The fuel pump is located inside the fuel tank and is responsible for delivering pressurized gasoline to the engine. When it fails, you will experience a loss of power, long cranking times, and eventually the engine will not start. Replacing the fuel pump typically costs between $300 and $500 for parts and labor, depending on where you take it and whether you do it yourself. This guide covers everything you need to know about the 2013 Dodge Avenger fuel pump, including symptoms, diagnosis, replacement options, and where to buy a reliable replacement.

Understanding the Fuel Pump in Your 2013 Dodge Avenger

The 2013 Dodge Avenger, equipped with a 2.4L four-cylinder engine, uses an electric fuel pump module assembly that sits inside the fuel tank. This design is common in modern vehicles because submerging the pump in fuel helps keep it cool and lubricated, extending its lifespan. The pump module includes the pump itself, a fuel level sending unit, and a strainer. When the pump fails, the entire module is often replaced as a unit.

The OEM part number for the 2013 Dodge Avenger fuel pump module is 68033083AG, which replaces earlier numbers like 68033083AB, 68033083AC, and 68033083AD. This module fits both the 2.4L engine and varies by emissions system—specifically, whether your car is a Partial Zero Emissions Vehicle (PZEV) or not. The standard replacement for non-PZEV models is the Detroit Axle FP76509M assembly, while the Mopar OEM kit includes the pump, sending unit, and O-ring.

Common Symptoms of a Bad Fuel Pump

Recognizing the signs of a failing fuel pump early can save you from being stranded. Here are the most common symptoms to watch for in your 2013 Dodge Avenger:

1. Whining noise from the fuel tank: A healthy fuel pump operates quietly. If you hear a loud humming or whining sound coming from the rear of the car, especially when the engine is running, the pump bearing is likely wearing out.

2. Engine sputtering or hesitation at high speeds: The fuel pump may not be delivering enough pressure to maintain proper fuel flow under load. You might feel the car "choke" or struggle to maintain speed, especially when accelerating or climbing hills.

3. Difficulty starting the engine: If the fuel pump is not building adequate pressure, you may notice the engine cranks longer than usual before it starts, or it may not start at all.

4. Engine stalling that restarts after a few minutes: This is a common sign of a failing pump. The pump may overheat and stop working, but after cooling down, it will work again temporarily.

5. Check Engine Light: A failing fuel pump can trigger the Check Engine Light with codes related to fuel system pressure or lean fuel mixture.

If you ignore these symptoms, the pump will eventually fail completely, leaving you unable to start the car. It is best to address the issue as soon as you notice any of these signs.

How to Diagnose a Failing Fuel Pump

Before replacing the fuel pump, it is important to confirm that the pump is actually the problem. A clogged fuel filter or a bad electrical circuit can cause similar symptoms. Here are the steps to diagnose the issue:

Step 1: Check the fuel pressure. Use a fuel pressure gauge to measure the pressure at the fuel rail. For the 2013 Dodge Avenger, the fuel pressure should be around 50-60 psi when the engine is running. If the pressure is low or drops quickly after the engine is turned off, the pump is likely failing.

Step 2: Listen for the pump. When you turn the ignition key to the "ON" position (without starting the engine), you should hear a brief whirring sound from the fuel tank as the pump primes the system. If you hear nothing, the pump may be dead or the electrical connection may be faulty.

Step 3: Inspect the fuel filter. A clogged fuel filter can restrict flow and mimic a failing pump. If the filter is old or dirty, replace it first and see if the symptoms improve.

Step 4: Check for electrical issues. Use a multimeter to test the voltage at the fuel pump connector. You should see 12 volts when the ignition is on. If there is no voltage, the problem may be a blown fuse, a bad relay, or a wiring issue.

Replacement Options for the 2013 Dodge Avenger Fuel Pump

There are several replacement options available, ranging from OEM Mopar parts to affordable aftermarket assemblies. The choice depends on your budget and whether you want to maintain original equipment quality.

OEM Mopar Fuel Pump Module

The Mopar fuel pump module kit (part number 68033083AG) is the direct replacement from the manufacturer. It includes the pump, sending unit, and O-ring. This is the most reliable option, but it is also the most expensive, with a list price of around $490 and a typical online price of about $329. It fits 2011-2014 Chrysler 200, 2008-2014 Dodge Avenger, and 2007-2010 Chrysler Sebring models with the 2.4L engine.

Aftermarket Fuel Pump Assemblies

Several aftermarket brands offer compatible fuel pump modules at lower prices. Here are some verified options:

Note: Some models are designed for PZEV (Partial Zero Emissions Vehicle) systems, while others are for non-PZEV. Check your vehicle's emissions system before ordering.

How to Replace the Fuel Pump in a 2013 Dodge Avenger

Replacing the fuel pump is a moderately difficult job. It requires basic mechanical skills and the right tools. Safety is critical because you are working with gasoline. Here is a step-by-step overview:

Step 1: Prepare the vehicle. Park the car on a flat surface and disconnect the negative battery terminal. Relieve the fuel system pressure by removing the fuel pump fuse and running the engine until it stalls. Then, open the gas cap to release any remaining pressure.

Step 2: Access the fuel pump. The fuel pump is located inside the fuel tank, which is under the rear seat. Remove the rear seat cushion by pulling up on the front edge to release the clips. You will see a metal access panel on the floor. Remove the screws or bolts to open the panel.

Step 3: Disconnect the fuel lines and electrical connector. Use a fuel line disconnect tool to separate the fuel lines from the pump module. Carefully unplug the electrical connector. Have a rag or container ready to catch any fuel that may spill.

Step 4: Remove the old pump module. Rotate the lock ring counterclockwise using a lock ring tool or a hammer and punch. Lift the pump module out of the tank. Note the orientation of the gasket and the float arm for proper installation.

Step 5: Install the new pump module. Place the new pump module into the tank, ensuring the gasket is seated properly. Rotate the lock ring clockwise to secure it. Reconnect the fuel lines and electrical connector.

Step 6: Test the system. Reconnect the battery, turn the ignition to the "ON" position without starting the engine, and listen for the pump to prime. Check for fuel leaks around the connections. If everything looks good, start the engine and verify normal operation.

Cost of Fuel Pump Replacement

The total cost of replacing the fuel pump on a 2013 Dodge Avenger depends on whether you do it yourself or hire a mechanic. Here is a breakdown:

• Parts only: Aftermarket fuel pump modules range from $54 to $100, while OEM Mopar parts cost around $329.
• Labor: Professional labor typically costs between $200 and $400, depending on the shop and location. The job takes about 1.5 to 3 hours.
• Total cost: If you use an aftermarket part and hire a mechanic, expect to pay $300 to $500. If you use an OEM part, the cost can be $600 to $800.

Tips to Extend Fuel Pump Life

To avoid premature fuel pump failure, follow these simple maintenance tips:

• Keep the fuel tank at least a quarter full. Running the tank low can cause the pump to overheat because the fuel helps cool it.
• Use high-quality fuel. Cheap or contaminated fuel can clog the filter and damage the pump.
• Replace the fuel filter regularly. A clogged filter puts extra strain on the pump. Check your owner's manual for the recommended replacement interval.
• Address Check Engine Light codes promptly. If the Check Engine Light comes on, have the system diagnosed as soon as possible to prevent further damage.

Conclusion

The fuel pump is a critical component of your 2013 Dodge Avenger, and knowing the symptoms of failure can save you time and money. If you notice a whining noise, difficulty starting, or engine hesitation, have the fuel system checked immediately. Replacement is a straightforward job for a DIY mechanic, but professional installation is also affordable. Whether you choose an OEM Mopar part or a reliable aftermarket option, make sure the part is compatible with your vehicle's engine and emissions system.
