If your 2009 GMC Acadia or other GM vehicle is suddenly stalling, hesitating, or refusing to start, the culprit is often not the fuel pump itself, but this critical component: the Fuel Pump Control Module (FPCM). As a technician with over two decades of experience, I’ve seen countless vehicle owners waste time and money replacing a perfectly good fuel pump when the FPCM was the real issue. This module is the electronic brain that tells your fuel pump how much pressure to deliver. When it fails, your engine is starved of fuel, leading to unreliable and often dangerous performance issues.
This isn’t just a replacement part; it’s a complete solution. We take a genuine GM-spec FPCM and flash it with the very latest official software updates specifically for your vehicle. All you have to do is provide your Vehicle Identification Number (VIN) during checkout. This means no expensive trips to the dealership for programming and no compatibility headaches. It arrives at your door ready for a straightforward installation, restoring your vehicle’s performance and reliability.
From the Diagnostic Bay: The Silverado That Wouldn’t Stay Running
A customer brought in an ’08 Silverado 1500 with a frustrating problem. It would start fine, but then stall intermittently, especially under load. They had already replaced the in-tank fuel pump, but the issue remained. Hooking up my scan tool, I saw a tell-tale code: P069E – Fuel Pump Control Module Requested MIL Illumination. Instead of guessing, we checked the FPCM, which on these trucks is notoriously exposed to road salt and moisture on the frame rail. Sure enough, corrosion had compromised the module. We installed a new, pre-programmed FPCM, and the truck ran perfectly. This is a classic case where diagnosing the controller, not just the pump, is the key to a successful repair.
Common Signs of a Failing FPCM
A faulty Fuel Pump Control Module can mimic a bad fuel pump. If you’re experiencing any of the following, this module is a likely cause. Look out for these symptoms and associated Diagnostic Trouble Codes (DTCs):
- âś” Engine cranks but will not start
- âś” Stalling, especially when the engine is warm or under load
- âś” Hesitation or stumbling during acceleration
- âś” Reduced engine power and poor performance
- âś” “Service Fuel System” message on the dash
- âś” Common trouble codes: P069E, P0230, U0109
A Straightforward Guide to Installation
Replacing your FPCM is a job most DIYers can handle with basic tools. Since this module comes pre-programmed, you skip the most difficult step. The module’s location varies by vehicle (see fitment list), but the general process is the same.
- Safety First: Disconnect the negative terminal from your vehicle’s battery.
- Locate the Module: Find the old FPCM. On many GM trucks and SUVs, it’s mounted on the driver-side frame rail near the spare tire. On vehicles like the Acadia or Traverse, it’s often on a rear crossmember.
- Disconnect and Remove: Carefully unplug the electrical connectors. Be gentle with the locking tabs, as they can become brittle. Then, unbolt the module from its mounting location.
- Install the New Module: Bolt the new, pre-programmed FPCM into place. Reconnect the electrical connectors, ensuring they click securely.
- Final Steps: Reconnect the negative battery terminal. Turn the key to the ‘On’ position for 10-15 seconds before starting to allow the system to prime. Start the vehicle and check for proper operation.

Frequently Asked Questions
Why do I need to provide my VIN?
Your VIN allows us to program the module with the exact software and calibrations specified by GM for your vehicle’s specific configuration. This ensures perfect compatibility and function right out of the box.
Is this part difficult to install?
For most individuals with basic mechanical skills, this is a straightforward replacement. The main challenge is accessing the module. Since our unit is pre-programmed, you avoid the need for special electronic tools or a trip to the dealer.
What happens if I install it without programming?
An unprogrammed module will not work. The vehicle’s computer systems will not recognize it, and your fuel pump will not operate, resulting in a no-start condition. Our pre-programming service solves this entirely.
Will this fix a check engine light for code P069E?
Yes, in the vast majority of cases, a faulty FPCM is the direct cause of a P069E code. Replacing the module with this correctly programmed unit is the standard, effective repair for that specific code.
Is this the same as a fuel pump?
No. The fuel pump is a mechanical device inside your gas tank that moves fuel. This is the Fuel Pump Control Module (FPCM), an electronic computer that tells the fuel pump how fast to run and when.
