If your 2008-2009 Chevy Tahoe is suddenly stalling, struggling to start, or showing a ‘Reduced Engine Power’ message, the culprit is often a failed Fuel Pump Control Module (FPCM). As a technician with over two decades of experience, I’ve seen this exact issue countless times. These modules, often called Fuel Pump Driver Modules, are notorious for failing due to their location on the frame rail, where they are constantly exposed to moisture, salt, and vibration. This exposure leads to internal corrosion and erratic fuel delivery, leaving you stranded.
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We take the guesswork and high dealership costs out of the equation. By providing your vehicle’s VIN at checkout, you will receive a 2008-2009 Tahoe FPCM that is professionally programmed with the latest GM software specifically for your vehicle. This means no expensive trips to the dealer for programming—it’s a true plug-and-play fix that you can perform right in your driveway.
From the Diagnostic Bay
I remember a 2008 Suburban that came into my shop on a flatbed. The owner was frustrated; he’d already replaced the fuel pump, but the truck would still crank but not start, and sometimes it would die while driving. The scanner was showing a P069E code—a classic sign of an FPCM communication failure. We located the original module on the driver-side frame rail, and it was corroded to pieces. After installing a new, programmed FPCM, the truck fired up on the first try and ran perfectly. This simple module was the key to solving a very frustrating and potentially expensive problem.
Common Signs of a Failing FPCM
A faulty fuel pump control module can mimic other fuel system problems. Before you consider replacing the entire fuel pump, check if your vehicle is exhibiting these specific symptoms. A failing 2008-2009 Tahoe FPCM will often cause:
- ✔ Engine stalling, especially under load or when coming to a stop.
- ✔ Extended cranking time before the engine starts.
- ✔ Complete no-start condition, even with a good battery.
- ✔ Check Engine Light with diagnostic trouble codes (DTCs) such as P069E, P0230, or P025A.
- ✔ Hesitation or sputtering during acceleration.
- ✔ A ‘Reduced Engine Power’ warning light on the instrument cluster.
A Straightforward Guide to Installation
Replacing the FPCM is a job most DIYers can handle with basic tools in under an hour. This module is typically located on the driver’s side frame rail, near the spare tire.
- Safety First: Disconnect the negative terminal from your vehicle’s battery.
- Locate the Module: Find the FPCM mounted to the frame crossmember. It’s a small, black plastic box with two electrical connectors.
- Disconnect: Carefully unplug the two electrical connectors. Press the release tabs and pull straight out. Avoid pulling on the wires themselves.
- Unbolt the Old Module: Use a socket wrench to remove the bolts securing the old module to the frame. It may be corroded, so a little penetrating oil can help.
- Install the New Module: Mount your new, pre-programmed 2008-2009 Tahoe FPCM in the same location and secure it with the original bolts.
- Reconnect and Finish: Plug the two electrical connectors firmly into the new module. Reconnect the negative battery terminal. Start the vehicle to confirm the repair is successful.

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 for your vehicle’s specific configuration. This ensures perfect compatibility and function right out of the box, eliminating the need for a separate programming service.
What does the Fuel Pump Control Module do?
The FPCM regulates the voltage sent to the electric fuel pump. Instead of running the pump at full speed all the time, it precisely controls the pump’s speed based on engine demand. This improves efficiency and the lifespan of the fuel pump.
Is this part difficult to replace myself?
No, for most individuals with basic hand tools, this is a very straightforward repair. The module is typically mounted on the vehicle’s frame and is accessible without removing major components. Our installation guide above provides the general steps.
Will this fix a P069E trouble code?
Yes, the DTC P069E is one of the most common codes indicating a failed FPCM. If you have diagnosed this code, replacing the module is the correct repair.
Where is this module located on my 2008 Tahoe?
On a 2008 Chevrolet Tahoe, the FPCM is mounted on a crossmember of the frame, typically on the driver’s side, above and forward of the spare tire.
