Restore Power and Reliability to Your GM Truck or SUV
There’s nothing more frustrating than a vehicle that cranks but won’t start, or one that sputters and dies unexpectedly in traffic. As a technician with over two decades of experience, I’ve seen this exact scenario play out hundreds of times on otherwise solid GM trucks. The culprit is often a failed Fuel Pump Control Module (FPCM), also known as a Fuel System Control Module (FSCM). This small but critical component, often mounted on the frame rail, takes a beating from road salt, water, and vibration, leading to internal failure and leaving you stranded. This isn’t just an inconvenience; it’s a safety issue.
This module is the definitive solution. We take a genuine GM-spec FPCM and pre-program it with the latest official software updates, tailored specifically to your vehicle’s VIN. This means you get a part that is truly plug-and-play. Forget about towing your truck to a dealership and paying extra for programming. With this module, you can perform the repair right in your driveway and get your vehicle back to factory-spec operation.
Is Your Vehicle Showing These Symptoms?
A failing FPCM can mimic a bad fuel pump, but it’s crucial to diagnose it correctly. If you’re experiencing any of the following, this module is likely the fix you need:
- ✔ Engine cranks but will not start.
- ✔ Vehicle starts and then immediately stalls.
- ✔ Severe hesitation or stumbling under acceleration.
- ✔ Loss of engine power, sometimes triggering ‘Reduced Engine Power’ mode.
- ✔ An active Check Engine Light with diagnostic trouble codes (DTCs) such as P069E, P0230, P0606, or U0109 (Lost Communication With Fuel Pump Control Module).
Case Study: The Ghost in the Fuel System
A customer brought in his 2008 Tahoe with a maddeningly intermittent problem. It would stall at random, sometimes at a stoplight, sometimes on the highway. Two different shops had told him he needed a new fuel pump. He’d already spent a fortune. I hooked up my scan tool and saw a U0109 code stored. Instead of dropping the tank, I went straight for the FPCM on the driver-side frame rail. It was caked in dirt and the connector showed early signs of corrosion. We installed one of our pre-programmed modules, and the problem was solved instantly. It’s a 20-minute fix that can save you from a thousand-dollar misdiagnosis. Always check the FPCM first on these trucks.
A Straightforward Guide to Installation
Replacing the 2008-2009 Sierra Denali FPCM is a job most DIYers can handle with basic tools. Since we program it beforehand, you skip the most complicated step.
- Safety First: Disconnect the negative terminal from your vehicle’s battery.
- Locate the Module: On most trucks and SUVs like the Sierra, Silverado, and Tahoe, the FPCM is mounted to the driver-side frame rail, typically just ahead of the spare tire. On other models, it may be on a rear crossmember or in the engine bay.
- Remove the Old Module: Unplug the electrical connector. Be gentle with the locking tab, as it can be brittle. Then, remove the bolts or nuts (usually two) holding the module to the frame.
- Install the New Module: Bolt the new, pre-programmed FPCM into place. Ensure it’s securely fastened.
- Connect and Finalize: Plug the electrical connector firmly into the new module until it clicks. Reconnect your battery terminal. The vehicle is now ready to start.

Frequently Asked Questions
Why do I need to provide my VIN?
Your vehicle’s VIN is essential for us to program the module with the exact software and calibrations required by GM for your specific model, year, and options. This ensures perfect compatibility and function right out of the box.
Is this a difficult part to install myself?
Not at all. For most DIYers with basic hand tools, this is a very straightforward repair. The module is typically easy to access on the frame rail, and since we handle the programming, it’s a simple bolt-off, bolt-on process.
Will this fix a P069E trouble code?
Yes, the DTC P069E (Fuel Pump Control Module Requested MIL Illumination) is one of the most common codes indicating a failed FPCM. Replacing the faulty module with this pre-programmed unit is the correct repair for that code.
What does the Fuel Pump Control Module do?
The FPCM acts as a smart controller for your fuel pump. Instead of running the pump at full speed all the time, the FPCM precisely regulates the voltage sent to the pump based on engine demand. This improves efficiency and extends the life of the fuel pump.
Is this a new or used part?
This is a high-quality, fully tested replacement module that has been loaded with new, vehicle-specific GM software. It is guaranteed to restore your vehicle’s fuel system to proper working order.
