Fuel Pump for 2013 Chevy Impala: Complete Replacement Guide, Costs, and Symptoms

The bottom line: If you own a 2013 Chevy Impala and are experiencing hard starting, engine sputtering, a whining noise from the rear of the car, or a check engine light related to fuel pressure, your fuel pump likely needs replacement. The total cost to replace the fuel pump on a 2013 Chevy Impala typically ranges from $350 to $900, with the part itself costing between $60 and $420 depending on whether you choose OEM or aftermarket components. Labor adds another $260 to $700 based on your location and the shop you choose.

How Much Does a Fuel Pump Replacement Cost for a 2013 Chevy Impala?

The actual price you pay will depend on several factors. Here is a realistic breakdown of what you can expect:

Part costs by type:

  • Aftermarket fuel pump module assembly: $60 to $230
  • OEM-equivalent fuel pump module: $200 to $420
  • Genuine GM fuel pump assembly: $195 to $512
  • High-pressure direct injection pump (if applicable): $225 to $485

Labor costs by shop type:

  • Independent mechanic: $260 to $500
  • Dealership service department: $400 to $700
  • DIY (you do the work yourself): $0 labor, but requires special tools

Additional fees you might encounter:

  • Diagnostic fee: $50 to $120
  • Fuel system inspection: $20 to $40
  • Disposal fees for old parts: $10 to $25
  • Shop supplies and taxes: $15 to $40

Most owners end up paying between $500 and $900 for a complete job at a reputable independent shop. If you go to a dealership and insist on genuine GM parts, you could easily exceed $1,000 to $1,300.

Signs Your 2013 Chevy Impala Fuel Pump Is Failing

Before you spend any money, it helps to know what symptoms point to a bad fuel pump. The fuel pump in your 2013 Impala is an electric pump located inside the fuel tank. When it starts to fail, you will notice one or more of these warning signs:

1. Engine cranks but won't start. This is the most obvious sign. You turn the key, the starter motor spins the engine, but it never fires up. The fuel pump is not delivering pressurized gasoline to the engine.

2. Sputtering or hesitation during acceleration. If your Impala feels sluggish when you step on the gas, especially going uphill or merging onto the highway, the pump may not be maintaining proper fuel pressure.

3. Engine stalls while driving. This is dangerous and can leave you stranded. The pump may work intermittently, cutting power to the engine at random times.

4. Whining noise coming from the fuel tank. A healthy fuel pump runs quietly. If you hear a loud whirring or humming sound from the rear of the car, especially when the ignition is first turned on, the pump bearings are wearing out.

5. Check engine light is on. The computer monitors fuel system pressure. If the pump is weak, it will trigger diagnostic trouble codes like P0087 (fuel rail pressure too low) or P0231 (fuel pump secondary circuit low).

6. Engine overheats. A failing fuel pump can cause the engine to run lean (too much air, not enough fuel), which increases combustion temperatures.

If you ignore these symptoms long enough, your Impala will eventually refuse to start altogether. It is best to address the problem as soon as you notice any of these issues.

Where Is the Fuel Pump Located on a 2013 Chevy Impala?

The fuel pump on your 2013 Chevy Impala is mounted inside the fuel tank. This is standard for modern vehicles with electronic fuel injection. The pump is submerged in gasoline, which helps keep it cool and reduces the risk of fire.

To access the pump, a mechanic must either:

  • Remove the fuel tank from underneath the vehicle
  • Access through an access panel inside the passenger compartment (some models have this, but most Impalas require tank removal)

Most 2013 Impalas require dropping the fuel tank, which makes this a moderately difficult repair that typically takes 3 to 5 hours for an experienced mechanic.

OEM vs Aftermarket Fuel Pump: Which Should You Choose?

When it comes time to buy a replacement fuel pump, you have two main choices. Here is how they compare:

OEM (Original Equipment Manufacturer) Parts:

  • Made by GM or licensed manufacturers like Delphi
  • Exact fit guaranteed for your 2013 Impala
  • Higher price: $195 to $512 for the pump assembly
  • Longer warranty: typically 12 months or more
  • Available at dealerships and online GM parts retailers

Aftermarket Parts:

  • Made by companies like TruGrade, Airtex, or Bosch
  • Lower price: $60 to $230 for the pump assembly
  • Quality varies by brand
  • Shorter warranty in some cases
  • Available at auto parts stores like AutoZone, O'Reilly, and RockAuto

For most drivers, a high-quality aftermarket pump is perfectly adequate. The key is to choose a reputable brand and check warranty terms before buying. If you plan to keep your Impala for many more years, spending extra on an OEM pump may give you peace of mind.

Step-by-Step Fuel Pump Replacement Process

If you are a skilled DIY mechanic, you can replace the fuel pump yourself and save several hundred dollars in labor. Here is the general process, but note that this is an advanced-level repair that requires safety precautions:

Tools and parts you will need:

  • New fuel pump module assembly (specific to your 2013 Impala)
  • New fuel pump module O-ring seal
  • Fuel line quick-disconnect tool set (5/16" and 3/8")
  • Floor jack and jack stands (3-ton minimum)
  • Socket set: 10mm, 13mm, 15mm
  • Flat-blade screwdriver
  • Fuel-safe drain pan and siphon pump
  • Safety glasses and nitrile gloves
  • Class B fire extinguisher

Step 1: Safety first. Park on level ground, set the parking brake, and chock the front wheels. Disconnect the negative battery cable using a 10mm socket. This prevents accidental sparks or electrical shorts.

Step 2: Relieve fuel pressure. Open the hood and locate the Schrader valve on the fuel rail (it looks like a tire valve). Wrap shop towels around it, then carefully depress the valve core with a flat-blade screwdriver to bleed pressure. Wear safety glasses because fuel can spray.

Step 3: Drain the fuel tank. Run the fuel level as low as possible before starting. If needed, use a hand siphon pump to remove remaining fuel into an approved container. A lighter tank is easier and safer to work with.

Step 4: Raise and support the vehicle. Use a floor jack to lift the rear of the car and place it securely on jack stands. Never work under a vehicle supported only by a jack.

Step 5: Support the fuel tank. Position a floor jack under the center of the fuel tank with a flat piece of wood between the jack and tank to spread the load. This prevents damage to the tank.

Step 6: Disconnect filler neck and vent connections. At the fuel fill area, loosen clamps and carefully work the hoses off. Twist gently and do not rip them.

Step 7: Lower the tank slightly. Use the floor jack to lower the tank just enough to access the top connections. Disconnect the electrical connector for the pump module. Use a fuel line quick-disconnect tool to release the fuel lines.

Step 8: Remove the old pump. Lower the tank completely. Use a brass drift punch and hammer to gently tap the lock ring counterclockwise to release it. Lift the old pump module out carefully. Be prepared for some fuel to spill.

Step 9: Install the new pump. Clean the tank opening area thoroughly. Place the new O-ring seal in position. Insert the new pump module assembly, making sure it is properly seated. Install the lock ring and tap it clockwise to secure it.

Step 10: Reassemble everything. Raise the tank back into position. Reconnect all fuel lines, electrical connectors, and vent hoses. Tighten all fittings securely. Reconnect the negative battery cable.

Step 11: Test the system. Turn the ignition to the ON position for 2-3 seconds, then OFF. Repeat this 3-4 times to prime the fuel system. This builds fuel pressure before you attempt to start the engine. Start the engine and check for any leaks.

What If the Fuel Pump Won't Prime After Replacement?

Sometimes, even after installing a brand new pump, the engine still won't start. Here is what to check:

1. Cycle the ignition properly. Turn the key to ON for 2-3 seconds, then OFF. Repeat 3-4 times. This allows the pump to run and build pressure. If you skip this step, the engine may crank but not fire.

2. Check fuses and relays. A blown fuel pump fuse or a bad relay will prevent the pump from running. Locate the fuel pump fuse in the fuse box under the hood or in the trunk. If it is blown, replace it and see if the pump works. If the new fuse blows immediately, there is a short in the wiring.

3. Inspect the wiring. Damaged or corroded wires can cut power to the pump. Look for breaks, fraying, or rust at the connector near the tank. If wiring tests show faults, professional repair may be required.

4. Test fuel pressure. Use a fuel pressure gauge connected to the Schrader valve on the fuel rail. The 2013 Impala should have around 55-60 PSI with the engine running. If pressure is low, the pump may be defective or the fuel filter may be clogged.

5. Check the anti-theft system. Some Chevy Impala models have a Passlock security system that can prevent the fuel pump from running if it detects tampering. If the security light is on or flashing, you may need to reset the system or re-learn the key. In some cases, dealer assistance is required.

Tips to Save Money on Your Fuel Pump Replacement

Replacing a fuel pump is not cheap, but there are ways to reduce the cost:

1. Buy the part yourself. If you can find a good deal on a quality fuel pump online, buy it and bring it to a mechanic. Many shops will install customer-supplied parts, though some may charge a slightly higher labor rate or refuse to warranty the work.

2. Get multiple quotes. Call at least three different shops in your area. Prices can vary by hundreds of dollars even for the same repair. Ask for a written quote that itemizes parts, labor, and any additional fees.

3. Ask about warranty. A reputable shop should warranty their labor for at least 12 months or 12,000 miles. The fuel pump itself should come with its own warranty from the manufacturer. Make sure you get documentation for both.

4. Consider replacing the fuel filter at the same time. If your Impala has a separate fuel filter, it is cheap insurance to replace it while the tank is already dropped. This can prevent future fuel system problems.

5. Have the fuel system inspected for leaks. After the new pump is installed, ask the shop to check for any fuel smells or drips. Catching a small leak early can prevent a much more expensive repair later.

Frequently Asked Questions

How long does a fuel pump replacement take on a 2013 Chevy Impala?
A professional mechanic typically needs 3 to 5 hours to complete the job. This includes removing the fuel tank, swapping the pump module, and reassembling everything.

Can I drive with a bad fuel pump?
You can, but it is not recommended. A failing pump can leave you stranded at any time. In some cases, a completely failed pump can cause damage to the fuel injectors or the engine itself.

Will a bad fuel pump damage my engine?
Yes. A weak pump can cause the engine to run lean (too little fuel), which increases cylinder temperatures. Over time, this can damage pistons, valves, and the catalytic converter.

Does the 2013 Chevy Impala have a fuel pump access panel?
Most 2013 Impalas do not have an access panel under the rear seat. The fuel tank must be removed from underneath the vehicle to access the pump. This is why labor costs are higher for this repair.

How often should the fuel pump be replaced?
Most fuel pumps last between 100,000 and 150,000 miles. If your Impala has high mileage and you are experiencing symptoms, it may be time for a replacement regardless of the pump's age.

What is the difference between a fuel pump and a fuel pump module?
The fuel pump module includes the pump, fuel level sending unit, strainer, and pressure regulator all in one assembly. This is what you need for your 2013 Impala. Buying the module ensures all components are replaced together, which is recommended.

Final Thoughts

Replacing the fuel pump on your 2013 Chevy Impala is a significant repair, but it is one that can restore your vehicle's reliability and performance. The cost typically falls between $350 and $900, and the job is best left to a professional unless you have advanced mechanical skills and the proper tools.

When choosing a replacement pump, prioritize quality and warranty over the lowest price. A cheap pump may fail sooner and cost you more in the long run. Brands like KEMSO offer the right balance of performance, durability, and value with the added security of a lifetime warranty.

If you are experiencing any of the symptoms described in this guide, do not wait. Have your fuel system inspected as soon as possible. A small problem now can become a major headache later if left unaddressed.
