2012 Jeep Grand Cherokee Fuel Pump: Complete Guide to Symptoms, Replacement, and Best Options
The bottom line: If your 2012 Jeep Grand Cherokee is experiencing hard starting, sputtering, loss of power, or a whining noise from the fuel tank, the fuel pump is likely failing. A replacement typically costs between $260 and $340 for the part alone, depending on the brand and whether you choose a module assembly or a standalone pump. Most owners can complete the replacement in 2-4 hours with basic mechanical skills, but professional installation adds $150-300 in labor.
Symptoms of a Failing Fuel Pump in Your 2012 Grand Cherokee
The fuel pump in your 2012 Jeep Grand Cherokee is responsible for delivering gasoline from the tank to the engine at the correct pressure. When it starts to fail, you will notice several warning signs. The most common symptom is engine sputtering or hesitation during acceleration, especially when going uphill or carrying a heavy load. You may also experience hard starting—the engine cranks longer than usual before firing up, or it may not start at all. Another clear indicator is a whining or humming noise coming from the rear of the vehicle near the fuel tank. This sound is often louder than normal and indicates the pump is working harder than it should. Loss of power during highway driving, where the vehicle feels like it is struggling to maintain speed, is also a classic symptom. Finally, if your check engine light comes on with a code related to fuel pressure or fuel system performance, the fuel pump is a likely culprit.
Which Fuel Pump Does Your Vehicle Need?
The 2012 Jeep Grand Cherokee uses different fuel pump configurations depending on the engine. The 3.6L V6 model and the 5.7L V8 model both use a primary fuel pump module located on the driver's side of the fuel tank . Some models also have a secondary module on the passenger side, but most failures occur in the primary unit. The pump is part of a module assembly that includes the pump itself, a fuel level sending unit, a strainer, and a pressure regulator. When you replace the pump, it is strongly recommended to replace the entire module assembly rather than just the pump alone. This ensures all components are fresh and prevents future failures. The OEM part number for the 2012 Grand Cherokee fuel pump module is 5145583AC or 5145583AB, and aftermarket equivalents include FG0855, P77190M, and SP7053M .
Replacement Cost and Options

Step-by-Step Replacement Overview
Replacing the fuel pump on a 2012 Jeep Grand Cherokee is a job that most DIYers can handle with basic tools. The fuel tank must be dropped or the rear seat removed to access the pump. Here is a simplified overview of the process:
- Relieve fuel system pressure by removing the fuel pump fuse and running the engine until it stalls.
- Disconnect the negative battery cable to prevent any electrical shorts.
- Remove the rear seat (if accessing from above) or support and lower the fuel tank (if accessing from below).
- Disconnect the electrical connectors and fuel lines from the pump module.
- Remove the locking ring using a special fuel pump removal tool or a hammer and punch.
- Lift out the old module assembly and transfer the fuel level float and any other necessary components to the new module.
- Install the new module with a new O-ring seal, and secure the locking ring.
- Reconnect everything, reinstall the seat or tank, and test for leaks before starting the engine.
Important Notes Before You Start
Fuel tank contamination is the leading cause of premature fuel pump failure. Before installing a new pump, it is highly recommended to clean the fuel tank. Delphi recommends using a fuel tank cleaning kit (FFC01) to remove debris and sediment that could damage the new pump . Also, always replace the fuel filter and strainer when you replace the pump. The strainer is included with most module assemblies, but if you buy a standalone pump, make sure to purchase a new strainer separately. Finally, use a torque wrench to tighten the locking ring to the manufacturer's specification—over-tightening can damage the seal and cause leaks.
