Restore Your Truck’s Reliability and Power
If you’re dealing with a 2008-2009 Avalanche that’s stalling, hesitating, or refusing to start, you know how frustrating it can be. In my 20+ years as a technician, I’ve seen countless owners replace their fuel pump, only to find the real problem was a faulty Fuel Pump Control Module (FPCM). This small but critical component, often called a fuel pump driver module, is responsible for managing the voltage sent to your fuel pump. When it fails, it starves your engine of fuel, leading to unpredictable and unsafe driving conditions.
Don’t get stuck on the side of the road. This isn’t just a replacement part; it’s a complete, ready-to-install solution. The biggest hurdle with FPCM replacement has always been the mandatory, and often expensive, trip to the dealership for programming. We eliminate that step entirely. By providing us with your vehicle’s VIN at checkout, we will flash this module with the latest GM-certified software specifically for your truck. It arrives at your door ready for a true plug-and-play installation, saving you time, money, and a major headache.
Is Your Truck Showing These Symptoms?
A failing FPCM can mimic other fuel system problems. Before you spend hundreds on a new fuel pump, check if your vehicle is experiencing any of the following. This is a common issue I diagnose for codes like P069E, P025A, or U0109.
- âś” Engine cranks but won’t start
- âś” Vehicle stalls unexpectedly, especially when warm
- âś” Stuttering or hesitation during acceleration
- âś” Reduced engine power and poor performance
- âś” A Check Engine Light is illuminated
- âś” Inconsistent fuel pressure readings on a scan tool
Case Study: A Tricky Diagnosis
I once had a 2008 Silverado 1500 in my bay with an intermittent stalling issue that was driving the owner crazy. He’d already been to two other shops; one replaced the fuel filter, the other wanted to drop the tank for a full pump assembly. The truck would run fine for days, then die at a stoplight. No codes were stored. I monitored the fuel pump command percentage on my scan tool during a long test drive. Just before it stalled, I saw the command signal from the FPCM drop to zero, even though the ECM was still requesting fuel. The module, located on the frame rail, had corrosion damage from years of exposure. A new, pre-programmed 2008-2009 Avalanche FPCM (same part for his Silverado) had him back on the road permanently in under an hour. It’s often the small parts that cause the biggest problems.
A Straightforward Guide to Installation
Installing your new, pre-programmed module is a job most DIYers can handle with basic tools. On most GM trucks and SUVs like the Avalanche, the FPCM is 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 old FPCM on the left-hand frame rail. It’s a small black box with electrical connectors.
- Disconnect and Remove: Carefully unplug the electrical connectors. Then, unbolt the module from the frame. These bolts can sometimes be rusty, so a little penetrating oil can help.
- Install the New Module: Bolt your new, VIN-programmed FPCM into the same location. Ensure it’s secure.
- Reconnect: Plug the electrical connectors firmly into the new module. You should hear a click.
- Final Step: Reconnect the negative battery terminal. Your vehicle is now ready to start with its properly functioning fuel system. No programming is required!

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 vehicle’s specific configuration. This ensures perfect compatibility and function right out of the box, saving you a trip to the dealer.
Is this part difficult to install?
Not at all. For most DIYers with basic hand tools, this is a straightforward, 30-minute job. Since we pre-program it, the installation is purely mechanical—just unbolt the old one and bolt in the new one.
What does the FPCM actually do?
The Fuel Pump Control Module acts as a smart relay. It receives commands from the Engine Control Module (ECM) and precisely controls the voltage and speed of the fuel pump to deliver the exact amount of fuel the engine needs at any given moment.
Will this fix a P069E check engine light code?
Yes, in a vast majority of cases. The DTC P069E (Fuel Pump Control Module Requested MIL Illumination) is a very common indicator that the FPCM itself has detected an internal fault or a problem with the circuit it controls. Replacing a faulty module is the standard, effective repair.
How do I send you my VIN?
After you complete your purchase, simply reply to your order confirmation email with your 17-digit VIN, or include it in the ‘notes to seller’ section during checkout. We cannot ship your order until we receive the VIN.
