2014 Chevy Cruze Fuel Pump Module Location: A Complete Owner's Guide
If your 2014 Chevy Cruze is cranking but won't start, sputtering at highway speeds, or making a loud whining noise from the rear of the car, the fuel pump module is the most likely culprit. Here is the bottom line up front: on the 2014 Chevy Cruze, the fuel pump module is located inside the fuel tank, which sits beneath the rear passenger seat area, just ahead of the rear axle. Unlike some vehicles that come from the factory with a convenient service access panel under the rear seat cushion, the Cruze does not have one. That means to reach the pump module, you will either need to lower the fuel tank from underneath the car or cut an access hole through the sheet metal beneath the rear seat. The electrical side of the system—the fuses and the fuel pump control module—is much easier to reach and should always be checked first before committing to a full pump replacement.
This guide walks you through exactly where the fuel pump module lives on the 2014 Cruze, how the fuel system is laid out, what symptoms point to a failing pump, how to test the electrical components, and what you can expect to pay for a replacement. Whether you plan to do the job yourself or hand it off to a shop, understanding the layout will save you time and money.
Where Exactly Is the Fuel Pump Module on a 2014 Chevy Cruze?
The 2014 Chevy Cruze uses an in-tank electric fuel pump module. This is the most common design for modern fuel-injected cars, and it means the pump sits submerged inside the gasoline tank itself. The tank on the Cruze is positioned beneath the rear passenger area, just ahead of the rear axle.
The fuel pump module is not just a pump. It is an assembly that typically includes the electric pump motor, the sending unit for the fuel gauge, the fuel strainer, and the pressure regulator. Because the entire assembly sits inside the tank, replacing it means getting into the tank one way or another.
Why does the pump live inside the tank? Submerging the pump in fuel keeps it cool and lubricated, which significantly extends its lifespan. The fuel itself acts as a coolant and lubricant for the pump's internal components. This design also reduces noise and prevents vapor lock, a problem that plagued older external pumps.
Two Ways to Access the Fuel Pump Module
Because the 2014 Cruze does not have a factory access panel, you have two practical options for reaching the pump module.
1. Lower the Fuel Tank (Recommended by Professional Service Procedures)
This is the method most professional technicians follow. It involves:
- Lifting the vehicle safely on jack stands
- Removing the fuel tank strap bolts—these are typically 15mm fasteners
- Disconnecting the fuel lines and the vent lines
- Unplugging the electrical connector to the pump module
- Lowering the tank carefully with a jack or a second person
Once the tank is down, you can unscrew the locking ring that secures the pump module to the top of the tank, lift the assembly out, and perform the replacement.
2. Cut an Access Panel Under the Rear Seat
Some owners and independent shops choose to cut a service hole through the sheet metal beneath the rear seat cushion. This avoids dropping the tank and can make future fuel pump service much easier if you plan to keep the car long-term. However, it requires care and comfort with cutting sheet metal. If you are not confident doing this, the tank-drop method is the safer, more traditional approach.
Check the Fuses and Relay Before You Pull the Pump
Before you go through the trouble of pulling the tank or cutting metal, check the electrical side. A surprising number of "bad fuel pump" cases turn out to be a blown fuse or a faulty relay.
On the 2014 Cruze, the fuel pump-related fuses are located in the engine compartment fuse box. This box sits under a black plastic cover right next to the battery. Open the cover and look for the fuse layout diagram printed on the underside of the lid or in your owner's manual. Here is what you are looking for:
- Fuse F18 (10A) — labeled "Fuel Pump Control Module"
- Fuse F28 (20A) — labeled "Fuel Pump Relay"
- Fuse F67 (20A) — also labeled "Fuel Pump Control Module," located further down in the box
In some documentation, you will also see Fuse F20 (20A) associated with the fuel pump relay circuit. The exact labeling can vary slightly depending on the trim level and build date, so always cross-check the diagram on your fuse box cover.
The Fuel Pump Control Module: A Common Source of Confusion
Here is where things get a little tricky on the Cruze. The fuel pump relay itself is designated as relay number 8 in the engine compartment fuse box. However, in many Cruze models, the relay is not present at all. Instead, GM substituted a Fuel Pump Control Module—a small electronic unit that performs the same switching function but is located in a completely different spot.
If you open the fuse box and find relay slot 8 empty, that is normal for many Cruze models. Do not assume a missing relay is your problem.
Where is the Fuel Pump Control Module? In models that have it, this module sits in the trunk, on the right-hand side, near the wheel arch. You may need to remove some trim or pull back the carpet lining to see it. Some owners also report finding it mounted near the rear seat back area on the passenger side.
How to Test the Fuses and Relay Without Expensive Tools
Testing the fuses is straightforward, and you do not need a fancy diagnostic scanner.
1. Visual Check
Pull the fuse with the plastic fuse puller tool—it is often clipped inside the fuse box lid. Look at the metal strip inside the fuse. If it is broken or melted, the fuse is blown and needs replacing.
2. Multimeter Check
Better yet, use a multimeter set to the continuity or ohms mode. Touch the two test leads to the small metal contacts on the top of the fuse. A good fuse will show near zero resistance or produce a beep on the continuity setting.
3. Relay Swap Test
To test the relay (if present), swap it with an identical relay from the same fuse box—like the powertrain relay or the horn relay—and see if the car starts. If it does, the original relay is bad. You can also listen for a click. When you turn the key to the ON position without cranking, you should hear the relay click and the pump prime for a couple of seconds.
Symptoms of a Failing Fuel Pump Module
Recognizing the warning signs early can save you from being stranded on the side of the road. Fuel pump failures rarely happen suddenly. They typically deteriorate gradually, giving you warning signs before complete failure.
1. Engine Sputtering or Stalling While Driving
If your engine suddenly loses power, sputters, or stalls while you are driving, especially at highway speeds or when climbing hills, the fuel pump may be failing. A weak pump cannot maintain consistent fuel pressure, causing the engine to hesitate or cut out entirely. This is one of the most dangerous symptoms because it can happen without warning.
2. Difficulty Starting the Engine
A failing fuel pump may not build enough pressure to deliver fuel to the engine, making it hard to start. You might notice that you have to crank the engine longer than usual, or the engine cranks but refuses to fire. In more advanced cases, the engine may not start at all.
3. Loss of Power During Acceleration
When you step on the gas pedal and the vehicle feels sluggish or unresponsive, the fuel pump may not be supplying enough fuel to meet the engine's demand. This is particularly noticeable when trying to merge onto highways or pass other vehicles.
4. Decreased Fuel Efficiency
If you notice that you are filling up more often than usual, a failing fuel pump could be to blame. When the pump cannot maintain proper pressure, the engine may run rich or lean, both of which waste fuel. Laboratory testing data reveals that fuel pumps operating at less than 80% of specified pressure result in a 12 to 18 percent reduction in fuel economy.
5. Loud Whining Noise from the Fuel Tank
A healthy fuel pump operates quietly. If you hear a loud whining, humming, or buzzing sound coming from the rear of the vehicle, especially near the fuel tank, the pump is likely failing. This noise indicates that the pump motor is working harder than normal due to wear, contamination, or internal damage.
6. Check Engine Light Illuminated
Modern Chevrolet vehicles monitor fuel system performance through the engine control unit. If the fuel pump is not delivering proper pressure or volume, the check engine light may come on. Diagnostic trouble codes related to fuel pressure or fuel trim issues often point to a failing pump.
What Causes a Fuel Pump to Fail?
Understanding why fuel pumps fail can help you prevent it from happening again.
1. Running the Tank Low
The fuel in the tank helps cool and lubricate the pump. Running the tank below a quarter full causes the pump to work harder and run hotter, which can shorten its lifespan dramatically. Lack of gasoline can kill a fuel pump in a matter of minutes.
2. Clogged Fuel Filter
A clogged fuel filter forces the pump to work harder to push fuel through to the engine. This added strain accelerates wear and can lead to premature pump failure. Replacing the filter on schedule—every 20,000 to 40,000 miles—is one of the cheapest and most effective ways to protect your fuel pump.
3. Contaminated Fuel
Debris, rust, or contaminated gasoline can clog the pump strainer and damage the internal components of the pump. Always buy fuel from reputable stations and avoid pumping gas when a tanker truck is refilling the station's underground tanks, as this can stir up sediment.
4. Normal Wear and Tear
Modern fuel pumps typically last between 100,000 and 150,000 miles, but driving habits, fuel quality, and maintenance practices significantly impact their lifespan. If your Cruze is approaching or has passed that mileage range and you are experiencing symptoms, the pump is a prime suspect.
How Much Does a Fuel Pump Replacement Cost?
The cost of replacing a fuel pump on a Chevrolet varies depending on the vehicle model, the type of pump required, and whether you choose a dealership or an independent repair shop.
For Chevrolet models, total costs typically range from $1,100 to $1,300, with parts between $500 and $600 and labor between $600 and $700. Dealership prices tend to be higher than independent shops.
Keep in mind that additional components such as the fuel filter, fuel pump relay, or fuel tank pressure sensor may need replacement at the same time, which can increase the total cost. A new fuel filter costs roughly $90 to $110, a fuel pump relay is about $45, and a fuel tank pressure sensor ranges from $125 to $200.
The job is considered moderately complicated because the fuel pump is typically located inside the fuel tank. To access it, the mechanic must either remove the fuel tank from the vehicle or access it through an interior panel beneath the rear seat. This labor-intensive process contributes significantly to the overall cost.
