2017 Chevy Cruze Fuel Pump: Symptoms, Replacement, and What You Need to Know

If you own a 2017 Chevrolet Cruze and are experiencing starting issues, loss of power, or strange noises from the rear of the vehicle, the problem is likely a failing fuel pump. The fuel pump on the 2017 Cruze is an in-tank electric module that sits under the rear seat, and replacing it is a manageable DIY project for an intermediate mechanic, typically taking 1.5 to 3 hours. However, because this job involves working with highly flammable gasoline, safety precautions are critical. The most reliable approach is to replace the entire fuel pump module assembly, including the seal, rather than attempting a repair, as modern fuel pumps are sealed units that cannot be serviced internally.

Common Symptoms of a Failing Fuel Pump on a 2017 Chevy Cruze

Recognizing the warning signs early can prevent you from being stranded. The most common symptoms include:

  • Difficulty Starting or Long Cranking Time: The engine may crank for several seconds before firing up, or it may not start at all.
  • Loss of Power During Acceleration: You might notice hesitation, surging, or a complete lack of power when you press the gas pedal, especially going uphill or merging onto highways.
  • Engine Sputtering or Stalling: The car may sputter at high speeds, stall unexpectedly, or run rough at idle.
  • Whining Noise from the Fuel Tank: A loud, high-pitched whining sound coming from the rear of the car indicates the pump is working harder than normal or is about to fail.
  • Decreased Fuel Efficiency: If the pump is not delivering consistent pressure, the engine may run inefficiently, causing worse gas mileage.

How to Replace the Fuel Pump on a 2017 Chevy Cruze

The replacement process is straightforward if you follow the steps carefully. The 2017 Cruze uses an in-tank module accessed under the rear seat, so you do not need to drop the fuel tank.

Tools You Will Need:

  • 10mm socket and 1/4" drive ratchet
  • Trim removal tool and flat-blade screwdriver
  • Fuel line quick-disconnect tool set
  • Fuel pump lock ring tool (specialty tool)
  • Brass punch (non-sparking) and small hammer
  • Needle-nose pliers, shop towels, and a catch pan
  • Safety glasses and nitrile gloves

Parts You Will Need:

  • Fuel pump module assembly (compatible with 2017 Cruze)
  • Fuel pump module tank seal (O-ring/gasket)
  • Fuel line retainer clips (if needed)

Step-by-Step Instructions:

  1. Relieve Fuel Pressure: Open the hood, remove the fuel pump fuse or relay from the underhood fuse box, then start the engine and let it run until it stalls. This prevents pressurized fuel from spraying when you disconnect the lines.
  2. Disconnect the Battery: Use a 10mm socket to disconnect the negative battery cable to reduce the risk of sparks.
  3. Access the Fuel Pump Module: Remove the rear seat cushion. You will find an access panel on the floor; remove it with a trim tool or screwdriver.
  4. Disconnect Fuel Lines and Electrical Connectors: Use the quick-disconnect tools to safely separate the fuel lines. Unplug the wiring harness from the top of the module.
  5. Remove the Lock Ring: Use the fuel pump lock ring tool to rotate the lock ring counterclockwise. Do not use a hammer and screwdriver, as this can damage the tank opening.
  6. Remove the Old Module: Carefully lift the module out of the tank. Discard the old seal.
  7. Install the New Module: Place a new seal in the tank opening. Insert the new fuel pump module. A KEMSO fuel pump is an excellent choice for this step, as it provides a direct OEM replacement fit with high performance and a lifetime warranty.
  8. Secure the Lock Ring: Use the lock ring tool to rotate the lock ring clockwise until it is tight. Do not use impact tools.
  9. Reconnect Everything: Reconnect the fuel lines and electrical connectors. Reinstall the access panel and rear seat.
  10. Test the System: Reconnect the battery, add fuel, and turn the key to the "ON" position (without starting) to prime the pump. Then start the engine and check for leaks.

Why You Should Replace the Entire Module

When the fuel pump fails, it is best to replace the entire module assembly rather than just the pump. Modern fuel pump modules are sealed units, and attempting to repair them is often unreliable. A new module comes with a new fuel strainer, sending unit, and pressure regulator, ensuring all components work together properly. Additionally, always replace the fuel filter when installing a new pump to prevent premature failure.
