2012 Chevy Cruze Fuel Pump Location: A Complete Owner's Guide

The bottom line up front: On the 2012 Chevy Cruze, the fuel pump is located inside the fuel tank, which sits beneath the rear passenger seat area. To reach it, you will typically need to remove the rear seat cushion to access a service panel on most models, although some trims may require lowering the fuel tank from underneath the car . The fuel pump fuses and relays, however, are much easier to find—they are located in the engine compartment fuse box next to the battery .

If you are experiencing hard starting, sputtering under acceleration, or a check engine light, the fuel system is often the first place to look. This guide walks you through finding the pump, checking the electrical components, recognizing the symptoms of failure, and understanding the costs involved.

Where Exactly Is the Fuel Pump Located?

The 2012 Chevy Cruze uses an in-tank electric fuel pump module, which is the standard design for modern fuel-injected cars . The pump sits submerged inside the gasoline tank, which is positioned beneath the rear passenger area, just ahead of the rear axle . This placement keeps the pump cool and lubricated by the fuel, which extends its lifespan .

On most Cruze models, you can reach the pump by removing the rear seat cushion to expose an access panel . However, some owners report that certain trim levels and build dates do not include this interior access door, meaning the fuel tank must be lowered from underneath to reach the pump . Before assuming your car has an access panel, check under the rear seat and underneath the car to see which setup applies to your specific vehicle .

If you need to lower the tank, the process typically involves:

1. Lifting the vehicle safely on jack stands.
2. Removing the fuel tank strap bolts, which are usually 15mm fasteners .
3. Disconnecting the fuel lines and vent lines .
4. Unplugging the electrical connector to the pump module .
5. Lowering the tank carefully with a jack or with help from a second person .

Once the tank is down, you can unscrew the locking ring securing the pump module to the top of the tank and lift the assembly out .

The Fuel Pump Fuse and Relay: What to Check First

Before going through the trouble of pulling the pump, always check the electrical side first. Many apparent fuel pump failures are actually blown fuses or faulty relays . On the 2012 Cruze, the fuel pump-related fuses are located in the engine compartment fuse box, under a black plastic cover next to the battery .

Here is what you are looking for:

1. Fuse F18 (10A) – labeled "Fuel Pump Control Module" .
2. Fuse F28 (20A) – labeled "Fuel Pump Relay" .
3. Fuse F67 (20A) – also labeled "Fuel Pump Control Module," located further down in the box .

The fuel pump relay itself is designated as relay number 8 in the engine compartment fuse box . However, on many 2011 and 2012 Cruze models, this relay is not present at all—instead, GM used a Fuel Pump Control Module, a small electronic unit 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.

Testing the fuses is straightforward. Pull each fuse with the plastic fuse puller tool and inspect the metal strip inside—if it is broken or melted, the fuse is blown . For a more reliable check, use a multimeter set to continuity mode and touch the leads to the small metal contacts on top of the fuse .

Six Warning Signs Your Fuel Pump Is Going Bad

Fuel pumps do not fail all at once. They typically give warning signs over days or weeks before quitting entirely . If you notice any of the following, start troubleshooting early before you end up stranded:

1. Long cranking time. The engine turns over for several seconds before it finally fires up because the pump is weak and takes longer to build fuel pressure .
2. Engine sputtering at speed. The car jerks or hesitates while driving, especially under load or on the highway .
3. Stalling that restarts after a few minutes. The engine dies suddenly but starts again after waiting—a classic sign of an overheating or failing pump motor .
4. Whining noise from the fuel tank area. A healthy pump makes a faint hum for 2–3 seconds when you turn the key to the ON position. A loud whine or buzz means the pump is struggling .
5. Loss of power while driving. The car feels sluggish and does not respond to the gas pedal because the pump is not delivering enough fuel volume .
6. Check Engine Light. A failing pump does not always trigger a warning light, but if fuel pressure drops significantly, the computer may set a fault code .

If your car cranks but will not start at all, and you hear no fuel pump hum when you turn the key to ON, the pump has likely failed completely .

Diagnose Before You Buy

Before spending money on a new pump, confirm that the pump is actually the problem. A clogged fuel filter or an electrical issue can produce symptoms identical to a bad pump . Here is how to narrow it down:

1. Check the fuse and relay first. Open the engine bay fuse box and inspect each fuel pump fuse. If any are blown, replace them with new fuses of the same amperage and retest .
2. Listen for the prime. Turn the key to the ON position without starting the engine. You should hear the pump hum for 2–3 seconds from the fuel tank area. If you hear nothing, the pump, relay, fuse, or wiring has an issue .
3. Use a fuel pressure gauge. A mechanic will attach a gauge to the fuel rail and check pressure while cranking. Low or absent pressure indicates a weak or dead pump. If pressure is fine, the problem lies elsewhere .
4. Scan for trouble codes. An OBD-II scanner can reveal codes related to the fuel system. Common codes for fuel volume regulator circuit issues are P0001, P0002, and P0003 .

How Much Does Replacement Cost?

A professional fuel pump replacement on a 2011–2012 Chevy Cruze typically costs between $958 and $1,078, with labor around $256–$376 and parts around $702 . A shop can usually handle the job in 1.5 to 3 hours, while many owners choose to do it themselves to save on labor costs .

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 . 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 .

How to Prevent Fuel Pump Failure

Preventive maintenance is the best way to extend the life of your fuel pump. Here are two essential tips:

1. Never let your fuel level drop below a quarter of a tank. The fuel in the tank cools and lubricates the pump. Running the tank low causes the pump to work harder and run hotter, which can shorten its lifespan dramatically .
2. Replace your fuel filter every 20,000 to 40,000 miles. A clogged fuel filter forces the pump to work harder to push fuel through, which accelerates wear and can lead to premature pump failure .
