2010 Buick Enclave Fuel Pump Control Module Location: What Every Owner Needs to Know

The 2010 Buick Enclave fuel pump control module is located on the driver’s side frame rail, near the spare tire area underneath the vehicle. If you’re dealing with stalling, hard starts, or a P069E trouble code, this small electronic module is often the culprit, and knowing exactly where it sits will save you both time and money.

The fuel pump control module (FPCM) on your 2010 Buick Enclave is a separate computer that tells the in-tank fuel pump how fast to run. It is not the same as the fuel pump assembly itself, which lives inside the fuel tank. On crossovers like the Enclave, the FPCM is typically mounted on the rear crossmember or along the driver’s side frame rail, exposed to road dirt and moisture—which is exactly why it fails so often. Before you spend hundreds of dollars on a new fuel pump, check this module first.

What Does the Fuel Pump Control Module Do?

The fuel pump control module is a networked computer that communicates with your Enclave’s Engine Control Module (ECM) and Body Control Module (BCM). Its job is to regulate the electrical power sent to the fuel pump, ensuring the engine receives the correct amount of fuel at all times. When this module fails, the fuel pump may run at full speed constantly, run erratically, or not run at all.

A failed FPCM can trigger a check engine light with code P069E (Fuel Pump Control Module Commanded On). This is the most common diagnostic indicator of a bad FSCM/FPCM on GM vehicles of this era.

Where Exactly Is the 2010 Buick Enclave Fuel Pump Control Module Located?

The short answer: On the 2010 Buick Enclave, the fuel pump control module is mounted underneath the vehicle, on the driver’s side frame rail, near the spare tire. On some crossovers like the Enclave and Traverse, you may also find it on the rear crossmember.

Here’s how to find it step by step:

  1. Raise the rear of the vehicle safely. Use a floor jack and jack stands. Never work under a car supported only by a jack.

  2. Look along the driver’s side frame rail. Starting from the rear wheel and moving toward the spare tire area, scan the frame rail for a small black module with a thick electrical connector. It is roughly the size of a paperback book.

  3. If you don’t see it on the frame rail, check the rear crossmember. On some Enclave models, the FPCM is bolted to the rear crossmember, which connects the two rear suspension arms.

  4. Look for a rectangular aluminum or plastic housing with a multi-pin connector. The connector typically has 43 terminals. This is your fuel pump control module.

Important: The FPCM is exposed to road elements, which is the primary reason it fails. Water, road salt, and debris can corrode the connector and damage the internal electronics.

How to Tell If Your Fuel Pump Control Module Is Failing

Before you crawl under your Enclave, here are the most common symptoms of a failing FPCM:

  • Engine stalls intermittently, especially after driving for a while
  • Hard starts or the engine cranks longer than usual before firing up
  • Check engine light with code P069E or related fuel pump codes
  • Reduced power or hesitation during acceleration
  • Fuel pump runs constantly or makes a loud whining noise
  • No fuel pump prime when you turn the key to the ON position

If you notice any of these, the FPCM is a much cheaper and easier part to replace than the in-tank fuel pump. GM even issued special coverage programs for this part due to its high failure rate.

Replacing the 2010 Buick Enclave Fuel Pump Control Module

Good news: Replacing the FPCM is a DIY-friendly job. You only need basic hand tools—typically a socket set and maybe a small pry tool. Here’s the general process:

  1. Disconnect the negative battery terminal. Always do this before working on any electrical component.

  2. Locate the module using the steps above.

  3. Disconnect the electrical connector. Press the release tab and pull straight out. Do not force it.

  4. Remove the mounting bolts. Use a socket or wrench to remove the bolts securing the module to the frame rail.

  5. Slide the module out. On some vehicles, you may need to slide the module sideways to disengage it from the bolt heads.

  6. Install the new module. Bolt it in place, reconnect the electrical connector, and reconnect the battery.

  7. Programming is required. Here’s the crucial part: A replacement FPCM must be programmed to your vehicle’s VIN. Simply installing a used or blank module without programming can lead to persistent no-start conditions or even damage your new fuel pump.

Programming Options

  • Buy a pre-programmed module. Many online sellers offer VIN-programmed units that arrive ready to install. You provide your 17-digit VIN after purchase, and they program it before shipping.

  • Have a dealer program it. If you buy a new GM module (part number 20877116) from a parts store, it will need dealer programming. For the 2010 Enclave, the OEM part number is 20877116, and it replaces earlier numbers 20791901, 20827745, and 20850927.

Fuel Pump vs. Fuel Pump Control Module: Don't Confuse Them

Many Enclave owners make the mistake of replacing the entire fuel pump assembly when the real problem is the control module. Here’s the difference:

Fuel Pump Assembly (in-tank module): The mechanical pump and fuel sending unit inside the gas tank. To replace it, you must drop the entire fuel tank—there is no access panel under the rear seat. This is an expensive, labor-intensive job.

Fuel Pump Control Module (FPCM): The small computer mounted on the frame rail or rear crossmember. It is cheap, easy to reach, and takes about 15 minutes to replace.

Given the high failure rate of the FPCM and the difficulty of accessing the in-tank pump, always diagnose the FPCM first. If a new FPCM solves the problem, you’ve saved yourself hundreds of dollars and hours of labor.

Part Numbers That Fit the 2010 Buick Enclave

If you’re ordering a replacement, you’ll want to match the correct part number. The following GM service numbers are interchangeable for the 2010-2012 Buick Enclave:

  • 20877116 (primary current number)
  • 20791901 (superseded)
  • 20827745 (superseded)
  • 20850927 (superseded)
  • 20791889 (earlier version)

The GM part number 20877116 is the current genuine replacement for the 2010 Buick Enclave with the 3.6L V6 engine. It weighs about 1.3 pounds and is a direct, bolt-in replacement.

Where to Buy a Replacement Fuel Pump Control Module

You have three main options when buying a replacement FPCM:

  1. GM Genuine Parts / ACDelco: Buy directly from a GM parts dealer. Expect to pay around $123 to $152 for a new unit. This option requires dealer programming.

  2. Pre-programmed aftermarket sellers: Companies like Highway 71 Auto Parts and Auto101 sell units already programmed to your VIN. These arrive ready to install and cost around $199.

  3. Used units: You’ll find used modules on sites like ShopEarl for around $97 to $109. Be aware that used modules still require programming, and their lifespan is unknown.
