Restore Your Truck’s Performance and Reliability
Is your 2008-2009 Sierra Denali experiencing frustrating and unpredictable issues like stalling, hesitation under load, or a crank-no-start condition? Before you condemn the in-tank fuel pump—a costly and labor-intensive job—consider the component that’s often the real culprit: the Fuel Pump Control Module (FPCM), also known as a Fuel Pump Driver Module. This module is the brain that tells your fuel pump how much pressure to deliver. When it fails, it can starve your engine of fuel, leading to a host of performance problems and leaving you stranded.
We offer a dependable, direct-fit solution with this FPCM. The best part? We handle the programming for you. Simply provide your vehicle’s VIN during checkout, and our technicians will flash the module with the latest GM software specific to your truck. This eliminates the need for an expensive trip to the dealership for programming, making this a true plug-and-play repair you can perform right in your driveway.
From the Diagnostic Bay: The Intermittent Stall Case
I remember a 2008 GMC Yukon XL that came into my shop with a maddening problem. The owner said it would randomly stall at red lights, but then fire right back up. He’d already replaced the fuel pump, but the issue persisted. When I hooked up my scan tool, I saw the dreaded DTC P069E – Fuel Pump Control Module Commanded OFF. Instead of just throwing parts at it, I monitored the FPCM data. The module was commanding the pump off intermittently due to internal overheating. We installed one of these pre-programmed modules, and the problem was solved instantly. It’s a classic case where diagnosing the controller, not the pump, saved the customer time and hundreds of dollars.
Is Your Truck Showing These Symptoms?
- ✔ Engine cranks but refuses to start.
- ✔ Sudden stalling, especially when coming to a stop or at idle.
- ✔ Noticeable hesitation or power loss during acceleration.
- ✔ An active Check Engine Light with codes like P069E, P0230, P2635, or U0109.
- ✔ Inconsistent fuel pressure readings.
- ✔ A fuel pump that doesn’t prime when the key is turned.
Your Straightforward Guide to Installation
Replacing the 2008-2009 Sierra Denali Fuel Pump Module is a job most DIYers can handle with basic tools. On most GM trucks and SUVs of this era, the module is mounted to the driver’s side frame rail, making it easily accessible.
- Safety First: Disconnect the negative terminal from your vehicle’s battery.
- Locate the Module: Find the FPCM, typically mounted on the inside of the driver-side frame rail, near the spare tire. It’s a small silver box with a single electrical connector.
- Disconnect and Remove: Unplug the electrical harness. Then, remove the bolts or nuts (usually 2) securing the module to the frame. The old module will come right off.
- Install the New Module: Mount your new, pre-programmed FPCM onto the frame and tighten the fasteners.
- Reconnect: Securely plug the electrical connector into the new module. You should hear a click.
- Final Steps: Reconnect the negative battery terminal. Cycle the key to the ‘On’ position a few times to prime the fuel system before starting the engine. Your installation is complete!

Frequently Asked Questions
Why do you need my VIN?
Your VIN is essential because it allows us to program the module with the exact software and calibrations specified by GM for your vehicle’s specific configuration. This ensures perfect communication with your truck’s other computers and guarantees proper fuel system operation right out of the box.
Is this part difficult to replace myself?
Not at all. For most DIY mechanics, this is a very straightforward repair. The module is typically located on the frame rail and held by just a couple of bolts. Since we pre-program it, no special tools or software are needed, making it a simple unbolt-and-replace job.
Will this fix a check engine light for code P069E?
Yes, in the vast majority of cases. DTC P069E (Fuel Pump Control Module Commanded OFF) is a primary indicator that the FPCM itself has failed. Replacing the module is the standard, correct repair for this specific code.
Where is this module located on my 2008 Sierra Denali?
On the 2008-2009 Sierra Denali, as with most GM trucks from this era, the FPCM is mounted to the driver’s side frame rail, usually above or near the spare tire. It’s exposed to the elements, which is a common reason for its failure.
Is this part the same as part number 20759945?
Yes. This module is a direct, interchangeable replacement for several GM part numbers, including 20759945, 25854536, 13501024, and others listed in the compatibility section. It meets or exceeds the original factory specifications.
