Restore Your Truck’s Power and Reliability
If your 2007-2009 Sierra 1500 is cranking but won’t start, stalling unexpectedly, or showing a ‘Reduced Engine Power’ message, the problem might not be your fuel pump. After 20 years of diagnosing these GM trucks, I’ve seen countless owners replace a perfectly good fuel pump when the real culprit was a failed Fuel Pump Control Module (FPCM). This module, often called a Fuel Pump Driver Module, is the brain that tells your fuel pump how much pressure to deliver. When it fails, your engine is starved of fuel, leading to frustrating and unpredictable performance issues.
From the Diagnostic Bay: The $800 Misdiagnosis
A customer brought in his ’08 Silverado, completely frustrated. He’d been chasing a stalling issue for weeks. First, he replaced the fuel filter. No change. Then, a local shop convinced him it was the in-tank fuel pump—a costly, labor-intensive job. When the truck stalled again on his way home, he came to my shop. A quick scan showed DTC P069E (Fuel Pump Control Module Commanded On). We didn’t even have to put it on the lift; I knew exactly where to look. The original FPCM on the frame rail was swollen and corroded. We installed a pre-programmed module, and the truck ran perfectly. He had spent over $800 chasing a problem this simple part solved in 15 minutes.
Is Your Truck Exhibiting These Fuel System Issues?
A failing FPCM doesn’t always trigger a check engine light right away, making it tricky to diagnose. Pay close attention if your vehicle shows any of these classic symptoms. A faulty 2007-2009 Sierra FPCM is often the root cause.
- âś” Engine cranks but refuses to start
- âś” Stalling while driving, especially under load or when coming to a stop
- âś” Hesitation or sputtering during acceleration
- âś” Noticeable loss of engine power
- âś” ‘Reduced Engine Power’ warning on the dashboard
- âś” Active Check Engine Light with codes like P069E, P0230, P0606, or U0109
The Smart Solution: Pre-Programmed and Ready to Install
Don’t waste time and money at the dealership. This FPCM arrives at your door completely programmed with the latest GM software updates specifically for your truck’s Vehicle Identification Number (VIN). This is a critical step that many sellers skip. Without proper programming, the module won’t communicate with your truck’s ECM, leaving you with the same problem. We handle the programming for you, turning a complex repair into a simple, plug-and-play installation you can do in your own driveway.
A Straightforward Guide to Installation
Replacing the FPCM is one of the easier repairs you can perform. On most GM trucks like the Sierra and Silverado, it’s located on the driver’s side frame rail, near the spare tire. You’ll only need basic hand tools.
- Safety First: Disconnect the negative terminal from your vehicle’s battery.
- Locate the Module: Find the old FPCM mounted to the frame crossmember. It’s a small black box with an electrical connector.
- Unplug and Unbolt: Carefully release the locking tab and disconnect the electrical harness. Then, remove the bolts holding the module to the frame. Due to its location, these bolts may be rusty, so a little penetrating oil can help.
- Install the New Module: Bolt the new, pre-programmed FPCM into place. Ensure it’s mounted securely.
- Connect and Secure: Plug the electrical connector into the new module. You should hear a ‘click’ as it locks into place.
- Final Step: Reconnect the negative battery terminal. Start the vehicle to confirm the repair is complete.

Frequently Asked Questions
Why do I need to provide my VIN?
Your VIN is required so we can program the module with the exact software and calibrations for your specific vehicle. This ensures 100% compatibility and proper function, eliminating the need for a dealership visit.
Is this part difficult to install?
No, this is a very DIY-friendly part. Since it comes pre-programmed, installation is as simple as unplugging the old module and plugging in the new one. It typically takes less than 30 minutes with basic hand tools.
What causes the original 2007-2009 Sierra FPCM to fail?
The most common cause of failure is its location. Mounted on the frame rail, it’s exposed to water, road salt, and debris, which leads to corrosion and internal electronic failure over time.
Will this fix a P069E check engine code?
Yes, in the vast majority of cases, the diagnostic trouble code P069E points directly to a failed Fuel Pump Control Module. Replacing it with this programmed unit is the correct repair for that code.
Is this different from the fuel pump?
Yes. The fuel pump is located inside your fuel tank and physically pumps the gasoline. This module is an electronic controller, typically on the frame, that tells the fuel pump how fast to run. They are two separate parts.
