Fuel Pump for 2016 Ford Fusion: Complete Guide to Symptoms, Replacement, and Cost

The bottom line: If you own a 2016 Ford Fusion and your engine is struggling to start, stalling unexpectedly, or making a whining noise from the rear of the car, your fuel pump is likely failing. A replacement typically costs between $844 and $1,104 for parts and labor, depending on your engine type and where you get the work done . The fuel pump is located inside the fuel tank, and replacing it is a moderately complex job best handled by a professional mechanic .

How the Fuel Pump Works in Your 2016 Ford Fusion

The fuel pump in your 2016 Ford Fusion is an electric unit mounted inside the fuel tank. Its job is to pressurize gasoline and deliver it to the engine so your car can run . The pump has a small electric motor that pushes fuel through a filter, then through the fuel lines, and finally to the engine's fuel injectors. Most fuel pumps are designed to last the entire life of the vehicle, but they can fail due to age, contamination, or electrical issues .

The 2016 Ford Fusion comes in several engine configurations, and the fuel pump setup varies between them. The standard gasoline models (2.5L, 1.5L EcoBoost, 2.0L EcoBoost) use a single in-tank fuel pump module. Hybrid and plug-in hybrid models (Fusion Energi) have a different pump assembly . Some EcoBoost engines also have a high-pressure fuel pump mounted on the engine itself, which works alongside the in-tank pump to deliver fuel at much higher pressures for direct injection .

Signs of a Bad Fuel Pump in a 2016 Ford Fusion

Recognizing the warning signs early can save you from being stranded. Here are the most common symptoms of a failing fuel pump:

1. Engine struggles to start or won't start at all. The most obvious sign is that your Fusion cranks but doesn't fire up. If the pump isn't delivering enough fuel pressure, the engine won't get the fuel it needs to start .

2. Engine stalling after starting. If your car starts fine but then stalls out a few minutes later, the fuel pump may be overheating or failing intermittently .

3. Sputtering or hesitation during acceleration. When you press the gas pedal, the engine may choke, hesitate, or feel like it's not getting enough fuel. This is especially noticeable when going uphill or merging onto the highway .

4. Whining noise from the fuel tank. A healthy fuel pump runs quietly. If you hear a loud whining or humming sound coming from the rear of the car near the gas tank, the pump is likely about to fail .

5. Engine overheating. A failing fuel pump can cause the engine to run lean (too little fuel), which can lead to overheating .

6. Check Engine Light comes on. The car's computer monitors fuel pressure and fuel trim. If the pump is not delivering consistent pressure, the Check Engine Light will illuminate, often with codes related to fuel system issues .

If you ignore these symptoms, the car will eventually refuse to start altogether. It's best to have a mechanic check it out as soon as possible .

Where Is the Fuel Pump Located?

The fuel pump on a 2016 Ford Fusion is located inside the fuel tank. To access it, a mechanic will either remove the rear seat and access it through a panel in the floor, or drop the entire fuel tank from underneath the vehicle . On most Fusion models, the fuel pump module is accessible through an access panel under the rear seat, which makes the job slightly easier .

The Fuel Pump Driver Module (FPDM) is a separate component that controls power to the pump. It is located behind the left C-pillar lower trim panel inside the passenger cabin . If the pump isn't getting power, the FPDM or the fuel pump relay could be the problem.

Diagnosing the Problem

Before replacing the fuel pump, a mechanic will perform a few tests to confirm it's the actual cause of the problem:

  • Check fuel pressure. A pressure gauge is connected to the fuel rail to see if the pump is delivering the correct pressure (typically 40-65 psi for most gasoline engines).
  • Check electrical supply. The mechanic will test if the pump is receiving proper voltage and ground. If the pump has power but doesn't run, the pump itself is bad. If there's no power, the issue could be a blown fuse, a bad relay, or a faulty FPDM .
  • Check the fuel pump fuse and relay. The 2016 Ford Fusion Energi, for example, has a fuel pump relay in the power distribution box under the hood, and a 30A fuse for the fuel pump power supply in the bottom of the same box . A blown fuse is often a symptom of a deeper problem, such as a short circuit or a dying pump that's drawing too much current .
  • Check the inertia switch. Some Ford vehicles have an impact sensor (inertia switch) that shuts off the fuel pump in a crash. If this switch has been accidentally triggered, the pump won't run .

Replacement Cost for a 2016 Ford Fusion Fuel Pump

The cost to replace a fuel pump on a 2016 Ford Fusion varies depending on your location and the shop you choose. Based on industry data, here are the estimated costs:

  • Average national cost range: $844 to $1,104 for a 2016 Ford Fusion .
  • Parts cost: The fuel pump module itself typically costs between $80 and $185 for aftermarket units, depending on the engine type . OEM (Motorcraft) parts will be more expensive.
  • Labor cost: The labor portion is usually $300 to $500, since the job requires dropping the fuel tank or removing the rear seat to access the pump.

For comparison, a 2008 Ford Fusion fuel pump replacement costs between $1,015 and $1,301, so the 2016 model is actually somewhat more affordable to repair .

Different Fuel Pump Types for Different Engines

The 2016 Ford Fusion came with multiple engine options, and the fuel pump you need depends on your specific engine:

1. 2.5L naturally aspirated engine (gas only). This engine uses a standard in-tank fuel pump module. The TRQ FPA64149 is a common aftermarket replacement for this engine, priced around $80.95 .

2. 1.5L EcoBoost engine (turbocharged). This engine uses a combination of an in-tank low-pressure pump and a high-pressure direct injection pump mounted on the engine. The high-pressure pump (Standard Motor Products GDP201) fits the 1.6L engine as well .

3. 2.0L EcoBoost engine (turbocharged). Similar to the 1.5L, this engine has both an in-tank pump and a high-pressure pump. The TRQ FPA61150 high-pressure pump costs about $184.95 .

4. Hybrid and plug-in hybrid (Fusion Energi). These models have a unique fuel pump module designed for the hybrid system. The TRQ FPA60990 is designed for the 2.0L plug-in hybrid, priced around $99.95 .

5. All-wheel-drive models. The 2.0L AWD Fusion may have a driver-side fuel pump module (TRQ FPA64145) that is different from the front-wheel-drive version .

Can You Replace the Fuel Pump Yourself?

Replacing a fuel pump is a moderately difficult job. If you have mechanical experience and the right tools, it's possible to do it yourself. The 2013-2020 Ford Fusion fuel pump replacement is covered in several video guides and repair manuals . Here's what you'll need:

Tools required: Floor jack, jack stands, socket set (7mm, 10mm, 13mm, T45 Torx), fuel line disconnect tool, trim tool set, flat blade screwdriver, hammer, pry bar, drain pan, safety glasses, and gloves .

Basic steps:

  1. Relieve fuel system pressure by removing the fuel pump fuse and running the engine until it stalls.
  2. Disconnect the battery.
  3. Remove the rear seat cushion to access the fuel pump access panel.
  4. Remove the access panel and disconnect the electrical connector and fuel lines.
  5. Remove the locking ring (using a brass punch and hammer) and lift out the old fuel pump module.
  6. Install the new fuel pump module, replace the locking ring, and reconnect everything.
  7. Reconnect the battery, install the fuse, and turn the key to the "on" position (without starting) to prime the fuel system.
  8. Check for leaks before starting the engine.

Important safety note: Gasoline is highly flammable. Work in a well-ventilated area, avoid sparks, and have a fire extinguisher nearby. If you're not comfortable with this job, it's best to leave it to a professional .
