2017 Jeep Grand Cherokee Fuel Pump: How to Spot Failure and Replace It Yourself

If you own a 2017 Jeep Grand Cherokee and notice symptoms like engine sputtering, hard starting, or a whining noise from the fuel tank, your fuel pump is likely failing. The best course of action is to replace the fuel pump module assembly promptly. A DIY replacement can save you between $470 and $600 compared to a shop, and the job typically takes 4 to 6 hours for an advanced home mechanic. This guide will walk you through the symptoms, the replacement process, and how to choose a reliable replacement part.

Common Signs of a Failing Fuel Pump in a 2017 Jeep Grand Cherokee

Fuel pump failure rarely happens without warning. Recognizing these symptoms early can prevent you from being stranded.

  • Engine sputtering or surging at high speeds: If your Grand Cherokee hesitates or jerks while driving at highway speeds, the pump may not be delivering a steady fuel flow.
  • Loss of power when accelerating: A failing pump cannot supply enough fuel pressure, especially when you need more power to climb a hill or pass another vehicle.
  • Difficulty starting the engine: If the engine cranks but takes longer than usual to start, or if it stalls shortly after starting, the fuel pump may be losing its prime.
  • Whining noise from the fuel tank: A healthy fuel pump runs quietly. A loud whining or humming sound coming from the rear of the vehicle is a classic sign of internal wear.
  • Decreased fuel efficiency: A pump that is struggling to maintain proper pressure forces the engine to work harder, reducing your miles per gallon.
  • Check engine light: The computer may trigger a diagnostic trouble code related to fuel system pressure, such as P0087 (Fuel Rail/System Pressure Too Low).

What You Need to Know Before You Start

Safety First

Fuel vapors are highly flammable. Always work outside or in a well-ventilated area. Disconnect the negative battery cable before opening the fuel system. Do not smoke, and keep a fire extinguisher nearby.

Tools Required

To replace the fuel pump on a 2017 Jeep Grand Cherokee, you will need:

  • 10mm and 13mm sockets
  • Ratchet and 1/4-inch drive extension
  • Flat blade trim tool
  • Fuel line disconnect tool set (for quick-connect fittings)
  • Fuel pump lock ring tool (specialty tool)
  • Torque wrench
  • Transmission jack or floor jack (rated 3-ton minimum)
  • Jack stands
  • Drain pan and shop towels
  • Safety glasses and nitrile gloves

Parts Required

  • Fuel pump module assembly – 1 unit
  • Fuel pump module seal/O-ring – 1 unit
  • Fuel tank lock ring – 1 unit
  • Fuel tank retaining strap bolts – 2 units

Step-by-Step Replacement Guide

Step 1: Relieve Fuel Pressure

Remove the fuel pump relay or fuse from the underhood fuse box. Start the engine and let it run until it stalls. Crank the engine for a few more seconds, then turn the key off.

Step 2: Disconnect the Battery

Use a 10mm socket to remove the negative battery cable. Isolate the cable so it cannot touch the terminal again.

Step 3: Access the Fuel Pump Module

On some Grand Cherokee models, there is an access panel under the rear seat. If yours has one, remove the rear seat lower cushion and use a flat blade trim tool to lift the access cover. If there is no access panel, you must lower the fuel tank.

Step 4: Remove the Fuel Tank (If Required)

Support the tank with a transmission jack or floor jack rated 3-ton minimum. Use a 13mm socket to remove the tank strap bolts. Lower the tank slightly and disconnect the electrical connector and vapor/fuel lines using the fuel line disconnect tool set. Lower the tank fully and move it out from under the vehicle.

Step 5: Disconnect the Module Connections

Clean around the fuel pump opening with shop towels to keep dirt out. Disconnect the electrical connector from the module. Release any fuel line quick-connects with the fuel line disconnect tool set.

Step 6: Remove the Lock Ring and Old Module

Use a fuel pump lock ring tool to turn the ring counterclockwise. Lift the lock ring off carefully. Remove the fuel pump module straight up and out of the tank.

Step 7: Install the New Module

Install the new fuel pump module seal/O-ring in the tank opening. Lower the new module straight into the tank. Install the lock ring and tighten it with the fuel pump lock ring tool until fully seated. Torque to factory specification.

Step 8: Reinstall the Tank

Raise the tank with the transmission jack. Reconnect the fuel lines and electrical connector. Install the tank straps with a 13mm socket and torque to factory specification.

Step 9: Reconnect Battery and Prime the Fuel System

Use a 10mm socket to reconnect the negative battery cable. Torque the battery terminal to 5 Nm (44 in-lbs). Reinstall the fuel pump fuse or relay. Turn the ignition to ON for 5 seconds without starting, then OFF for 10 seconds. Repeat this ON/OFF cycle 3 times to prime the fuel system.

Step 10: Check for Leaks and Test Drive

Start the engine and let it idle. Check under your Grand Cherokee for fuel leaks near the tank, fuel line connections, and filler hose. If the engine cranks longer than normal, turn the key off and repeat the prime cycle. Confirm the fuel gauge reads normally. Road test for 10-15 minutes, then recheck for leaks. If the check engine light is on, scan for codes and clear them after confirming the repair is leak-free.

Choosing the Right Fuel Pump for Your 2017 Grand Cherokee

The 2017 Jeep Grand Cherokee came with several engine options, including the 3.6L V6, 5.7L V8, and a 3.0L diesel. Each engine requires a specific fuel pump module. Always verify compatibility with your vehicle's engine size and model year before purchasing.

Many aftermarket fuel pump modules are available that directly replace the original equipment. For example, the PHILTOP FG0855 is compatible with the 2016-2022 Grand Cherokee 3.6L and the 2011-2022 Grand Cherokee 5.7L. The Herko 860GE is designed for the 2014-2019 Grand Cherokee 3.0L diesel. The Mopar 68535771AB is the OEM fuel pump/level unit module kit for many 2017 Grand Cherokee models.
