If your 2008-2009 Chevrolet Tahoe is experiencing frustrating and potentially dangerous issues like stalling, hesitation under acceleration, or a complete no-start condition, a faulty Fuel Pump Control Module (FPCM) is the most common cause. As a technician with over two decades of experience, I’ve seen these exact symptoms hundreds of times on GM trucks and SUVs. The original module, often mounted on the frame rail, is highly susceptible to corrosion from road salt and moisture, leading to erratic fuel pressure and engine performance problems.
This isn’t just a replacement part; it’s a complete, ready-to-install solution. The biggest headache with replacing an FPCM has always been the mandatory, and costly, trip to the dealership for programming. We eliminate that step entirely. By providing us with your vehicle’s VIN at checkout, we will program this module with the latest official GM software specifically for your Tahoe. This ensures perfect communication with your vehicle’s powertrain control module (PCM) and restores factory performance and fuel efficiency. You get a part that is truly plug-and-play, saving you time, money, and the hassle of scheduling a dealer appointment.
Is Your Tahoe Showing These Signs of a Failing FPCM?
- ✔ Engine stalls unexpectedly, especially at low speeds or idle.
- ✔ Vehicle cranks but will not start.
- ✔ Noticeable hesitation or stumbling during acceleration.
- ✔ Reduced Engine Power message displayed on the dash.
- ✔ Check Engine Light illuminated with fuel system-related Diagnostic Trouble Codes (DTCs) such as P069E, P0230, or U0109.
- ✔ Inconsistent fuel gauge readings or a pump that seems to run continuously.
From the Diagnostic Bay
I remember a customer with a 2008 Tahoe who was at his wit’s end. His SUV would die randomly in traffic, but then restart after a few minutes. Multiple shops had failed to find the issue because it was so intermittent. When it got to my bay, I hooked up a scan tool with live data capability. I could see the FPCM commanding erratic voltage to the fuel pump, causing pressure to drop off a cliff. The module itself, located on the frame rail, was swollen and corroded. We replaced it with a VIN-programmed unit like this one, and the fix took less than 30 minutes. The customer called a week later, overjoyed that his Tahoe was finally reliable again. This is a common story for this specific part.
A Straightforward Guide to Installation
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before beginning any electrical work.
- ✔ Locate the Module: On the 2008-2009 Tahoe, the FPCM is typically mounted to the driver’s side (LH) frame rail, near the spare tire.
- ✔ Disconnect and Remove: Carefully unplug the electrical connector. Be sure to press the release tab to avoid damage. Then, remove the bolts (usually 10mm or 13mm) securing the old module to the frame.
- ✔ Install the New Module: Mount your new, pre-programmed FPCM in the same location using the original hardware. Ensure it is securely fastened.
- ✔ Reconnect and Finalize: Plug the electrical connector firmly into the new module until it clicks. Reconnect your battery’s negative terminal. The vehicle is now ready to start with no further programming needed.
By purchasing this pre-programmed 2008-2009 Tahoe FPCM, you are choosing a reliable, professional-grade fix that restores the integrity of your vehicle’s fuel delivery system. It’s the smart, efficient way to get your truck back on the road with confidence.

Frequently Asked Questions
Do I need to take this part to a dealer for programming?
No. We program the module to your vehicle’s specific VIN before we ship it to you. It arrives ready for a direct, plug-and-play installation.
What information do you need from me?
After you complete your purchase, you must provide us with your 17-digit Vehicle Identification Number (VIN). We cannot ship the module without it.
Where is the FPCM located on my 2008 Tahoe?
It is typically mounted on the driver’s side frame rail, often above or near the spare tire.
Will this fix a P069E check engine light code?
Yes, DTC P069E (Fuel Pump Control Module Commanded Performance) is one of the most common codes indicating a failed FPCM. Replacing the module is the correct repair for this fault.
What tools are required for the installation?
You will only need basic hand tools. A socket wrench with a 10mm or 13mm socket is typically all that is required to remove the mounting bolts.
