2014 Chevy Cruze Fuel Pump Control Module Location: Where to Find It and How to Fix Fuel Delivery Problems

The 2014 Chevy Cruze fuel pump control module is located in the trunk, mounted on the right-hand (passenger side) wheel arch behind the interior trim panel. This small electronic module controls the speed and pressure of the in-tank fuel pump, and when it fails, your Cruze may crank but not start, stall while driving, or trigger a check engine light with fuel-related trouble codes. Understanding exactly where this module lives, what it does, and how to diagnose it can save you hundreds of dollars in unnecessary parts and diagnostic fees.

This guide covers everything a 2014 Cruze owner needs to know: the exact module location, step-by-step access instructions, common symptoms of failure, the difference between the control module and the fuel pump relay, and how to test the system before replacing anything.

What the Fuel Pump Control Module Actually Does

The fuel pump control module on a 2014 Cruze is not the fuel pump itself. It is an electronic control unit that sits between the engine control module (ECM) and the electric fuel pump inside the tank. Here is how the system works:

1. The ECM sends a signal to the fuel pump control module based on engine demand, throttle position, and other sensor inputs.
2. The control module adjusts voltage going to the in-tank fuel pump, telling it how fast to spin.
3. The pump delivers fuel at the exact pressure needed for any driving condition, whether you are idling in traffic or merging onto a highway.

This setup is part of a returnless fuel system, which means fuel is delivered to the engine at variable pressure rather than circulating back to the tank. The control module also monitors the pump's current draw and reports problems back to the ECM. When the module fails, you may see diagnostic trouble codes such as P0087 (fuel rail pressure too low) or P0628 (fuel pump control circuit low).

2014 Chevy Cruze Fuel Pump Control Module Location: Step-by-Step

The module is mounted on the right-hand wheel arch inside the trunk. This is the passenger side on American-market cars. It is a small black or gray plastic box, roughly 3 inches by 4 inches, with a multi-wire harness plugged into it. Here is how to access it:

1. Open the trunk and remove the cargo floor mat.
2. Pull back the carpet on the right side. The wheel arch is the curved metal area that covers the rear wheel on the inside of the trunk. In many Cruze models, the carpet pulls away from clips, but take care not to tear it.
3. Locate the module secured to the wheel arch. It may be bolted or clipped to the sheet metal, and some models have a metal bracket holding it in place.
4. Take a photo or label the harness before unplugging anything. This helps you reconnect everything correctly.

This same location applies to other GM models from that era, including the Buick Verano and the Chevrolet Sonic. If you are working on a Cruze from any model year between 2011 and 2016, the location is essentially the same.

Fuel Pump Relay and Fuses: Different Location, Different Job

While the control module handles fine-tuning of fuel pressure, the fuses and relay serve as safety switches. On the 2014 Cruze, the fuel-related fuses and relay are in the engine compartment fuse box, under the black cover next to the battery. Here is what to look for:

1. Fuse F18 – Fuel Pump Control Module (10A). This fuse protects the control module circuit. If it is blown, the module gets no power and the pump will not run.
2. Fuse F20 – Fuel Pump (20A). This is the main fuse for the fuel pump power circuit. Some sources list it as a 20A fuse; others reference fuse number 67 as another fuel pump control module fuse in later models.
3. Relay #8 – Fuel Pump Relay. On some Cruze models, this relay position may be empty because the control module replaces the relay function. Check your fuse box cover diagram for confirmation.
4. Fuse F28 – Fuel Pump Relay (20A). Some sources list this as the fuse for the fuel pump relay circuit itself.

If you are having fuel delivery problems, check these fuses first with a test light or multimeter. A blown fuse is the cheapest possible fix, and it takes about two minutes to check.

Symptoms of a Bad Fuel Pump Control Module

A failing control module can produce several distinct symptoms. Recognizing them early can help you avoid being stranded and may reduce repair costs.

1. Engine cranks but will not start. This happens when the module completely fails and no power reaches the fuel pump. You might hear the pump prime for a second when you turn the key, then nothing.
2. The pump runs constantly at full speed. This is a classic control module failure. The module gets stuck in "full on" mode, so the pump pushes maximum pressure all the time. You will hear a loud whine from the fuel tank area, and the engine may run rich.
3. Hard starting and long crank times. The module might not deliver enough voltage to the pump during startup, making the engine difficult to start.
4. Intermittent starting problems. The vehicle may start normally one day and refuse to start the next. This inconsistent behavior is a hallmark of an electronic module failure rather than a mechanical pump issue.
5. Engine stalling or hesitation during acceleration. A failing module may deliver inconsistent power to the fuel pump, causing the engine to surge, hesitate, or stall, especially under load.
6. Check engine light illuminated. A diagnostic scan will typically reveal fault codes related to the fuel pump circuit or control module communication.

How to Test the Fuses and Relay Before Replacing the Module

Testing the fuses is straightforward and does not require expensive tools. 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. Better yet, use a multimeter set to 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.

If the fuses and relay check out but the pump still does not run, the control module is the next component to test. A qualified technician can command the pump on with a scan tool and measure voltage at the module connector to confirm the diagnosis.

Fuel Pump Control Module Replacement Cost

If the control module needs replacement, the cost depends on whether you choose a dealership or an independent shop, and whether you use OEM or aftermarket parts. For most 2014 Chevrolet Cruze models, a complete fuel pump control module replacement—parts and labor combined—typically ranges from $400 to $1,100.

The module itself accounts for $150 to $700 of that total, while labor typically runs $200 to $500 depending on accessibility and shop rates. For a mid-range scenario covering most Chevrolet models from 2010 to 2022, quality aftermarket modules with solid warranties or remanufactured OEM units plus standard labor at independent shops or chain service centers run about $605 to $1,100.

If you are comfortable working on your own vehicle, the module replacement is a relatively straightforward job. The module is accessible from the trunk without dropping the fuel tank, which keeps labor costs reasonable.

Frequently Asked Questions

Q: Can I drive with a bad fuel pump control module?

A: It is not safe to drive with a failing control module. The engine may stall without warning, leaving you stranded in traffic or on the highway. If you suspect the module is failing, have the vehicle diagnosed and repaired before driving it further.

Q: Is the fuel pump control module the same as the fuel pump relay?

A: No. The control module regulates voltage to the fuel pump for variable pressure control. The relay is a simple on/off switch. On many 2014 Cruze models, the control module replaces the relay function entirely, which is why the relay slot in the fuse box may be empty.

Q: How long does it take to replace the fuel pump control module?

A: A professional technician can typically replace the module in one to two hours, since it is located in the trunk and does not require dropping the fuel tank. If you are doing the job yourself, allow two to three hours for careful removal of trim panels and proper reconnection of the wiring harness.

Q: Will a bad control module always trigger a check engine light?

A: Not always. In some cases, the module fails in a way that does not immediately set a code. However, most failures will eventually trigger a check engine light with codes such as P0087 or P0628. If you are experiencing fuel delivery symptoms but no code is present, a technician can still test the module with a scan tool.
