2012 Chevy Cruze Fuel Pump Control Module: Complete Guide to Symptoms, Location, and Replacement

The bottom line up front: If your 2012 Chevy Cruze is cranking but won't start, stalling intermittently, or showing a check engine light, the fuel pump control module (FPCM) is a likely culprit. On the 2012 Cruze, this module is a separate electronic component that controls power delivery to the in-tank fuel pump, and replacing it typically costs between $250 and $550 depending on whether you use OEM or aftermarket parts and whether you do the work yourself or hire a shop. The good news is that on many 2012 Cruze models, the FPCM is located inside the vehicle (in the trunk area), making it one of the most affordable fuel system repairs you can tackle.

Unlike the fuel pump itself, which sits inside the fuel tank under the rear seat and requires dropping the tank or cutting an access panel, the fuel pump control module is much easier to reach on most 2012 Cruze trims. This guide covers everything you need to know: what the FPCM does, how to recognize failure symptoms, where to find the module, how to test it, what replacement costs to expect, and whether you should consider a DIY fix or professional repair.

What Is the Fuel Pump Control Module and Why Does It Matter?

The fuel pump control module is an electronic component that regulates the voltage and current supplied to the fuel pump . In modern vehicles with electronic fuel injection, the engine control unit sends signals to the FPCM, which then controls the fuel pump's operation . When you turn the ignition key, battery power is sent to the fuel pump, which operates for 3 to 4 seconds to build fuel pressure in the fuel lines . The FPCM ensures the fuel pump receives the correct amount of power at the right time .

On the 2012 Chevy Cruze specifically, GM used a fuel pump control module in place of a traditional relay in many models . This means the module performs the same switching function as a relay but is located in a completely different spot . If you open the engine compartment fuse box and find relay slot 8 empty, that is normal for many Cruze models—do not assume a missing relay is your problem .

The FPCM is critical because it varies the pump speed based on engine demand, which improves fuel efficiency, reduces noise, and extends the life of the fuel pump . When it fails, the pump doesn't get the signal to operate, and your engine won't receive fuel .

Common Symptoms of a Failing Fuel Pump Control Module

Recognizing the warning signs early can save you from being stranded and potentially reduce repair costs . Here are the most common symptoms to watch for:

  1. Engine Cranks But Won't Start – If you turn the key and hear the motor cranking normally, but the engine doesn't catch or start, you're most likely facing a fuel pump control module issue. This is because the fuel pump motor isn't running, and sufficient fuel pressure isn't reaching the engine .

  2. 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 .

  3. Engine Stalling or Hesitation During Acceleration – A failing FPCM may deliver inconsistent power to the fuel pump, causing the engine to surge, hesitate, or stall, especially under load .

  4. Check Engine Light Illuminated – Modern vehicles will trigger the check engine light when the FPCM sends abnormal signals or fails to communicate with the ECU . On the 2012 Cruze, diagnostic scan tools may reveal fault codes related to fuel pump circuit or control module communication .

  5. No Fuel Pump Prime Noise – When you turn the ignition to the ON position (without starting the engine), you should hear a brief whirring sound from the fuel tank area as the pump pressurizes the system. If that sound is absent and the vehicle has no fuel pressure, the FPCM is a likely suspect .

  6. Reduced Performance and Increased Fuel Consumption – When the fuel pump isn't receiving proper voltage, it may run at reduced capacity, leading to poor acceleration, reduced power, and higher fuel consumption .

Where Is the Fuel Pump Control Module Located on a 2012 Chevy Cruze?

The location of the FPCM varies significantly by vehicle make and model . For the 2012 Chevy Cruze, here's what you need to know:

In models that have the separate control module, it 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 .

The module is a small black electronic unit with a wiring harness connected to it . In some 2012 Cruze configurations, the module may also be located under the carpeting or in a fender well, which requires more disassembly .

Important distinction: The fuel pump itself is a completely different component. On the 2011-2012 Chevy Cruze, the fuel pump is located inside the fuel tank, which sits under the rear seat area of the car . There is no exterior access panel on this model, meaning you'll need to either lower the fuel tank or cut through the sheet metal beneath the rear seat to reach the pump assembly . The fuel pump fuses and relays, on the other hand, are located in the engine compartment fuse box under the black cover next to the battery .

How to Diagnose a Faulty Fuel Pump Control Module

Before spending money on parts, take time to confirm the FPCM is actually the issue. Here's a professional diagnostic approach you can follow at home:

Step 1: Scan for Codes – Use a quality OBD2 scanner to retrieve any stored trouble codes. Look for codes related to fuel pump control module malfunction or fuel pump circuit issues . Common codes on GM vehicles include P0629 (Fuel Pump Control Module Range/Performance Problem) and B11AF (Fuel Pump Control Module Malfunction) .

Step 2: Visual Inspection – Open the trunk and locate the FPCM. Check for obvious signs of damage: corroded pins, melted plastic, water intrusion, or loose connectors. In many cases, a simple cleaning or reseating of the connector fixes the issue .

Step 3: Check the Fuses First – Before going through the trouble of replacing the module, check the electrical side. On the 2012 Cruze, the fuel pump-related fuses are located in the engine compartment fuse box . Look 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"

Test each fuse with a multimeter set to continuity mode. A good fuse will show near zero resistance or produce a beep .

Step 4: Voltage and Ground Testing – Use a multimeter to test the power and ground pins at the FPCM connector. You should see battery voltage (around 12.6V) on the power pin with the key on. If the voltage is low or absent, the problem is likely in the wiring or fuse, not the module itself .

Step 5: Listen for the Prime – After performing any repairs, reconnect the module, turn the key to ON, and listen for the fuel pump prime. If the pump runs and the check engine light stays off, the repair was successful .

Fuel Pump Control Module Replacement Cost for 2012 Chevy Cruze

The cost to replace the fuel pump control module varies depending on whether you DIY or take it to a shop:

DIY replacement – A new OEM or high-quality aftermarket FPCM typically costs between $80 and $200. The module itself is relatively inexpensive, and the labor is minimal since it is located inside the vehicle, not under the car . For the 2012 Cruze, this is the smartest route if you have basic tools and a little mechanical confidence.

Professional repair – If you take the vehicle to a dealership or independent shop, expect to pay between $250 and $550 total. This includes parts, labor, and any reprogramming that may be required . Dealership rates will run higher than independent shops, but you get the benefit of factory-trained technicians and OEM parts.

Complete fuel pump replacement comparison – For context, a full fuel pump assembly replacement on most vehicles typically ranges from $400 to $1,100 for parts and labor combined . The module itself accounts for $150 to $700 of that total, while labor typically runs $200 to $500 depending on accessibility and shop rates . Replacing just the control module is significantly cheaper because you don't need to drop the fuel tank or cut access panels.

Step-by-Step: How to Replace the Fuel Pump Control Module

If you've confirmed the FPCM is bad, here's how to replace it on your 2012 Chevy Cruze:

  1. Disconnect the battery – Remove the negative battery cable before you do any work near electrical components. This prevents accidental sparks or short circuits .

  2. Access the module – Open the trunk and locate the FPCM on the right-hand side near the wheel arch. You may need to remove some trim or pull back the carpet lining .

  3. Disconnect the wiring harness – Carefully unplug the electrical connector from the module. Check for corrosion or damage to the pins .

  4. Remove the old module – The module is typically held in place by a bracket or mounting screws. Remove these fasteners and take out the old unit.

  5. Install the new module – Position the new FPCM in the bracket and secure it with the same fasteners. Reconnect the wiring harness, making sure the connector clicks into place firmly.

  6. Reconnect the battery and test – Turn the key to the ON position and listen for the fuel pump prime. If you hear the whirring sound from the fuel tank area, the new module is working .

  7. Clear any codes – Use an OBD2 scanner to clear any stored trouble codes and confirm the check engine light stays off.

Common Mistakes to Avoid

  1. Replacing the fuel pump instead of the module – Many owners assume a no-start condition means the fuel pump is dead. On the 2012 Cruze, the pump itself is buried inside the fuel tank, making it an expensive and labor-intensive job. Always test the module first .

  2. Assuming a missing relay is the problem – In many 2012 Cruze models, relay slot 8 in the fuse box is empty because GM substituted a fuel pump control module in its place. Do not assume a missing relay is your problem .

  3. Skipping the fuse check – A surprising number of "bad fuel pump control module" cases turn out to be a blown fuse or a faulty relay . Check fuses F18, F28, and F67 before replacing any components.

  4. Using the wrong replacement part – Make sure you order the correct FPCM for your specific Cruze trim level and build date. The exact labeling can vary slightly depending on the trim level and build date .

  5. Forgetting to relieve fuel system pressure – This applies mainly to fuel pump replacement, but if you end up doing the full pump assembly, always start the engine and pull the fuel pump relay, letting the engine run until it stalls. This depressurizes the fuel lines so gasoline doesn't spray when you disconnect them .

Should You DIY or Hire a Professional?

For the fuel pump control module replacement on a 2012 Chevy Cruze, most DIYers with basic tools and a little experience can handle the job. The module is accessible from the trunk, doesn't require dropping the fuel tank, and typically takes under an hour to replace. If you're comfortable working with electrical connectors and basic hand tools, you can easily save $150 to $350 in labor costs by doing it yourself.

However, if you're not comfortable working on your vehicle or you've confirmed additional issues with the fuel pump assembly itself, hiring a professional is the safer option. A failing fuel pump can send metal fragments or plastic debris into your fuel system, damaging the fuel injectors and the engine itself .
