2010 Camaro Fuel Pump Control Module: Symptoms, Replacement, and What You Need to Know

The bottom line up front: If you own a 2010 Chevrolet Camaro and are experiencing stalling, hesitation, or a no-start condition, the fuel pump control module (FPCM) is very likely the culprit. This small electronic module regulates the voltage sent to your fuel pump, and when it fails, your engine gets starved of the fuel it needs to run properly. Replacing it with a VIN-programmed direct replacement—like the units that interchange with part numbers 20831727, 20831728, and 20875846—will typically resolve these issues without needing a trip to the dealership. The module is usually located in the rear of the vehicle, often in the trunk or rear compartment area, making it a straightforward DIY project for someone with basic mechanical skills.

This guide will walk you through everything you need to know about the 2010 Camaro fuel pump control module, including how it works, the common symptoms of failure, how to diagnose it properly, your replacement options, and step-by-step installation guidance. We will also cover what to look for when buying a replacement and why choosing a quality part matters for the long-term health of your Camaro.

What Does the Fuel Pump Control Module Do?

The fuel pump control module, sometimes referred to as the FPCM or fuel pump driver module, acts as the brain between your engine control module (ECM) and the fuel pump itself. In modern vehicles like the 2010 Camaro, this module does much more than just turn the fuel pump on and off. It constantly adjusts the pump's speed and voltage to meet the engine's exact fuel demand at any given moment.

Here is how the system works according to GM's service information:

  1. ECM sends the signal. When you turn the ignition on, the ECM supplies voltage to the FPCM. This voltage remains active for about two seconds unless the engine is cranking or running.
  2. FPCM takes over. While receiving that voltage, the FPCM closes the ground switch for the fuel pump and supplies a varying voltage to the fuel tank pump module to maintain the desired fuel rail pressure.
  3. Fuel delivery happens. The fuel system in the 2010 Camaro is a returnless on-demand design. The fuel pressure regulator is built into the fuel pump module, which eliminates the need for a return pipe from the engine. This design reduces the internal temperature of the fuel tank and lowers evaporative emissions.

On the 3.6L V6 models, the fuel system is an electronic returnless on-demand design. An electric turbine-style fuel pump attaches to the primary fuel pump module inside the fuel tank. The pump supplies fuel through the fuel feed pipe to a high-pressure fuel pump, which then supplies fuel to a variable-pressure fuel rail. The high-pressure fuel pump, fuel rail pressure, fuel injection timing, and injection duration are all controlled by the ECM.

Common Symptoms of a Failing FPCM

A failing fuel pump control module can show up in several different ways. Knowing these signs will help you diagnose the problem before you end up stranded. Here are the most frequently reported symptoms:

  • Engine stalling at idle or when stopping. This is one of the most common issues resolved by replacing a faulty FPCM. Your Camaro may run fine while cruising, but when you slow down or come to a stop, the engine dies.
  • No-start condition where the engine cranks but won't turn over. The starter motor spins the engine, but it never fires up because fuel is not reaching the injectors at the correct pressure.
  • Hesitation or stumbling during acceleration. When you press the gas pedal, the car may sputter or hesitate instead of responding smoothly. This is often caused by inconsistent fuel pressure delivery.
  • Reduced engine power and poor fuel economy. If the fuel pump is not receiving proper voltage, it cannot supply enough fuel, which results in noticeable performance drops and worse gas mileage.
  • Check Engine Light with diagnostic trouble codes. The most common codes associated with a faulty FPCM include P069E, P0230, and P0627.

If you are experiencing any of these symptoms, the FPCM should be high on your list of suspects. However, it is always wise to confirm the diagnosis before buying parts.

How to Diagnose a Faulty Fuel Pump Control Module

Before you replace anything, you need to verify that the FPCM is actually the problem. GM's service information provides a straightforward testing procedure that can help you narrow things down. Here is a simplified version of that diagnostic process:

Step 1: Check for power at the fuel pump.

  1. Turn the ignition off and disconnect the harness connector at the fuel pump (labeled G12 in the service manual).
  2. Connect a test lamp between the control circuit terminal 1 and ground.
  3. Turn the ignition on and command the fuel pump on and off using a scan tool's ECM output control. The test lamp should turn on and off as commanded.

If the test lamp stays on all the time, you likely have a short to voltage in the control circuit. If the circuit tests normal, then the K27 fuel pump control module is the likely culprit and should be replaced.

If the test lamp never comes on, test the control circuit for a short to ground or an open/high resistance condition. Again, if the circuit tests normal, replace the K27 fuel pump control module.

Step 2: Check the low reference circuit.

  1. With the ignition off, connect a test lamp between the control circuit terminal 1 and the low reference circuit terminal 2.
  2. Turn the ignition on and command the fuel pump on using the scan tool.
  3. The test lamp should illuminate. If it does not, test the low reference circuit for a short to voltage or an open/high resistance. If that circuit tests normal, replace the K27 fuel pump control module.

Step 3: Check the fuel pump itself.

If all the circuits test normal, then the problem is likely the fuel pump assembly itself (the G12 unit), and it should be replaced.

This diagnostic procedure applies to both the 3.6L V6 and 6.2L V8 versions of the 2010 Camaro. While this process requires a scan tool and some electrical testing knowledge, it will save you from replacing parts unnecessarily. If you do not feel comfortable doing this kind of testing, a professional shop can perform it for you.

Replacement Options for the 2010 Camaro FPCM

Once you have confirmed that the FPCM is faulty, you have several replacement options. The most important thing to understand is that this module requires programming to work correctly with your vehicle. A module from a junkyard or a generic parts store that has not been programmed to your VIN simply will not work—it does not know your car's specific parameters.

OEM Programmed Modules

Several online retailers sell new or refurbished GM fuel pump control modules that are pre-programmed to your vehicle's VIN. These are the most convenient options because they are truly plug-and-play.

Part numbers to know: The 2010 Camaro FPCM is a direct replacement for several part numbers, including 20831727, 20831728, and 20875846. Some listings also reference 20867261 as a related part number for the fuel pump flow control module used across multiple GM vehicles.

What to expect from a programmed module: These units have the latest GM software calibration loaded before they ship. This ensures the module communicates correctly with your vehicle's ECM right out of the box, restoring precise fuel delivery and original performance. This eliminates the need for expensive dealer programming.

Warranty considerations: Most reputable sellers offer at least a one-year replacement warranty on their programmed modules. Always check what kind of warranty is included before you purchase.

The Factory GM Part

If you prefer to go with a brand-new factory part and handle the programming yourself, the genuine GM fuel pump flow control module carries part number 20867261. This is described as fitting the Equinox, Terrain, Camaro (without supercharger), Cruze, Caprice PPV, Verano, and Volt across various model years from 2010 to 2013. This part requires programming and/or special setup procedures as described in GM Service Information.

A word of caution: When ordering a factory part, make sure you get the correct one for your engine and trim level. The 2010 Camaro came with a 3.6L V6 or a 6.2L V8, and the module should fit both naturally aspirated versions. If you have the supercharged version, you will need a different part number.

Used Modules with VIN Programming

Some sellers offer used OEM fuel pump control modules that are tested, functional, and programmed to your VIN. These can be a budget-friendly option. For example, listings for used 2010-2015 Camaro fuel pump control modules with OEM part number 22872265 have appeared on auction sites, often described as "used but fully functional" and sold with a return policy. Just be sure to verify the part number against your original module and confirm the seller is willing to program it to your VIN before purchase.

The Importance of VIN Programming

You might be wondering why you need to provide your VIN when buying a replacement FPCM. The reason is simple: your vehicle's Vehicle Identification Number tells the module exactly which GM software and calibrations are needed for your specific car's engine, transmission, and options.

Modern GM fuel systems are incredibly sophisticated. The FPCM does not simply turn the fuel pump on or off; it constantly adjusts the pump's speed to match the engine's exact demand. This is why programming is absolutely critical. An unprogrammed module does not know your car's parameters and will not function correctly.

When you order a VIN-programmed module, the seller flashes the unit with the correct software before shipping it to you. This makes the installation a true plug-and-play experience—no special tools, no dealer visits, and no additional programming required.

Installation Overview

Replacing the FPCM on your 2010 Camaro is a manageable task for someone with basic DIY skills. Here is what you can expect:

  1. Locate the module. The module is typically located in the rear of the vehicle, often in the trunk or rear compartment area. On some GM vehicles, it may be in the left side rear compartment.
  2. Disconnect the battery. As with any electrical work on your vehicle, start by disconnecting the negative battery cable to prevent accidental shorts.
  3. Remove the old module. The module is usually held in place with a few bolts and one electrical connector. Remove the bolts and unplug the connector.
  4. Install the new module. If you purchased a VIN-programmed module, simply plug in the new unit and secure it with the bolts. It should be ready to work immediately.
  5. Reconnect the battery and test. Reconnect the battery, turn the ignition on, and verify that the fuel pump primes and the vehicle starts normally.

If you are not comfortable working on your vehicle, professional installation is always recommended. The job is straightforward enough that many owners do it themselves, but there is no shame in letting a professional handle it.

Additional Considerations: Relearn Procedures

Depending on the specific module and calibration, your 2010 Camaro may require one or more post-install procedures after replacing the FPCM. These can include theft-deterrent/security relearn, crankshaft variation learn, idle or throttle learn, transmission adaptive/fast learn, or module setup with a capable scan tool.

Required relearns vary by vehicle, module type, and calibration. If your replacement module comes from a company that specializes in GM programming, they should be able to advise you on whether any additional steps are needed. If you are unsure, a local GM dealership or a qualified independent shop can handle these procedures for you.

How to Choose the Right Replacement Part

When you are shopping for a replacement FPCM, keep these tips in mind:

  1. Verify your original part number. Before ordering, remove your old module and check the part number on the label. This will help you confirm compatibility with any replacement you are considering. You can also send photos of the original module label to the seller for verification.
  2. Confirm the seller programs to your VIN. Make sure the seller actually flashes the module to your VIN before shipping. This is the difference between a plug-and-play install and a frustrating experience.
  3. Check the warranty. Look for a seller that offers at least a one-year replacement warranty. This gives you peace of mind and protects you against defects.
  4. Read the fitment notes. Some modules fit multiple GM vehicles, including the Equinox and Terrain, in addition to the Camaro. Just because a module fits those vehicles does not guarantee it is correct for your specific engine and options, so double-check the application list.
