2014 Chevy Cruze Fuel Pump Access: Step-by-Step Guide for Replacement
The Bottom Line Up Front
If your 2014 Chevy Cruze is cranking but won't start, sputtering during acceleration, or making a loud whining noise from the rear of the car, the fuel pump is the most likely culprit. The 2014 Chevy Cruze, like the 2011 model, uses an in-tank electric fuel pump module located inside the fuel tank beneath the rear passenger seat area. Unlike some vehicles that come with a factory service access panel under the rear seat cushion, the Cruze does not have one. This means you have two options: drop the fuel tank from underneath the car or cut an access hole through the sheet metal under the rear seat. Before you commit to either job, check the fuel pump fuse and relay in the engine compartment fuse box—a surprising number of "bad fuel pump" cases turn out to be a blown fuse or a faulty relay.
Where Exactly Is the Fuel Pump on a 2014 Chevy Cruze?
The 2014 Chevy Cruze uses an in-tank electric fuel pump module, which is the most common design for modern fuel-injected cars. The pump sits submerged inside the gasoline tank itself. The tank is positioned beneath the rear passenger area, just ahead of the rear axle.
Unlike some vehicles that provide a service access hatch under the rear seat cushion, the Cruze does not come from the factory with a convenient cutout. In GM's design, the sheet metal of the floor pan sits solid over the pump assembly. If you need to reach the pump without dropping the tank, you'll need to cut an access hole in the metal—a job that many owners and technicians have performed successfully, but one that requires care.
The alternative, and the method recommended by most professional service procedures, is to lower the fuel tank from underneath the car.
Option 1: Dropping the Fuel Tank (Recommended Method)
This is the safer, more traditional approach. Here is what the job involves:
- Lift the vehicle safely on jack stands. Make sure the car is secure before you get underneath it.
- Remove the fuel tank strap bolts—these are typically 15mm fasteners.
- Disconnect the fuel lines and the vent lines.
- Unplug the electrical connector to the pump module.
- Lower 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.
This method takes more time, but it does not involve cutting into your car's floor pan. If you are not comfortable with cutting sheet metal, this is the way to go.
Option 2: Cutting an Access Panel Under the Rear Seat
Many owners and technicians have successfully cut an access hole through the sheet metal beneath the rear seat to reach the pump assembly. This method saves time on the current job and makes future fuel pump service much easier if you plan to keep the car long-term.
However, this job requires care. You need to measure carefully to locate the pump directly below, and you must avoid cutting into fuel lines, wiring, or the tank itself. If you are not confident with this kind of work, the tank drop is the safer approach.
Some video tutorials show both methods side by side, and the decision really comes down to whether you want to cut an access panel or invest the extra time in dropping the tank.
Check the Fuse and Relay First
Before you go through the trouble of pulling the pump, 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'll 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 relay itself is designated as relay number 8 in the engine compartment fuse box. However, this is where things get a little tricky on the Cruze. In many 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.
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.
How to Test the Fuses and Relay Without Expensive Tools
Testing the fuses is straightforward, and you don't need a fancy diagnostic scanner. Pull the fuse with the plastic fuse puller tool—it's often clipped inside the fuse box lid. Look at the metal strip inside the fuse. If it's broken or melted, the fuse is blown and needs replacing.
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.
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.
- Listen for a click. When you turn the key to the ON position (without cranking), you should hear a click.
Symptoms of a Failing Fuel Pump
The most common symptom is a whining noise coming from the fuel tank area. A healthy pump makes a quiet hum, but a failing pump will sound louder, like a high-pitched whine. You may also experience:
- Difficulty starting the car, especially after it has been sitting for a while.
- The engine sputters at high speeds or loses power when you go uphill.
- The car starts but then stalls after a few seconds.
- The engine will not start at all if the pump fails completely.
If you notice any of these signs, check the fuel filter first. A clogged fuel filter is the number one cause of fuel pump failure because the pump has to work harder to push fuel through the restriction, which creates heat and stress.
What Causes Fuel Pump Failure
Running the tank low on fuel is the biggest mistake drivers make. The fuel in the tank acts as a coolant for the pump. When the tank is low, the pump runs hotter, which shortens its life.
Dirt and debris from a clogged fuel filter also damage the pump. Old fuel that has sat for years can turn into a varnish-like substance that gums up the pump internals. Electrical issues like a bad relay or corroded wiring can also cause the pump to fail.
How the Fuel Filter and Fuel Pump Work Together
These two parts are connected in a way that affects each other's lifespan. Think of the fuel system as a loop. The pump pushes fuel from the tank, through the filter, and to the engine. The filter protects the engine and the pump from contamination.
When the filter is clean, the pump works easily. When the filter is clogged, the pump has to work harder. A clogged filter creates back pressure. The pump strains to push fuel through, which generates more heat. The heat breaks down the pump's internal lubricants and seals. Eventually, the pump wears out and fails.
In many cases, what seems like a pump failure is actually just a clogged filter. Always replace the filter first before assuming the pump is bad. If you are replacing the fuel pump, it is smart to replace the fuel filter at the same time. The old filter may still have debris that could damage the new pump.
