Restore Your Truck’s Power and Reliability
There’s nothing more frustrating than a truck that won’t start or stalls without warning. If your 2008-2009 Chevrolet Avalanche 1500 is experiencing erratic fuel delivery, long crank times, or has simply left you stranded, a failing Fuel Pump Control Module (FPCM) is a very common cause. This isn’t just an inconvenience; it’s a critical component for your engine’s performance and health. This module, also known as a Fuel Pump Driver Module, precisely regulates the voltage sent to your fuel pump. When it fails, your fuel pressure becomes unstable, leading to a host of drivability problems.
I had a 2008 Silverado 1500 in my bay last month with a classic crank-no-start condition and a P069E trouble code. The owner had already replaced the in-tank fuel pump, but the problem persisted. On these GM trucks, the FPCM is mounted to the driver-side frame rail, exposed to years of road salt and moisture. A visual inspection showed the module’s casing was swollen from corrosion. After swapping it with a new, programmed unit, the truck fired right up and fuel pressure held steady. It’s a textbook example of how this small module can cause major headaches.
Is Your Truck Showing These Symptoms?
A failing FPCM can mimic other fuel system issues. Here are the most common indicators I’ve seen in my 20+ years of diagnostics. If you’re experiencing any of these, this module is the likely solution.
- ✔ Engine cranks but will not start
- ✔ Stalling, especially under load or when coming to a stop
- ✔ Hesitation or stumbling during acceleration
- ✔ Reduced engine power and poor fuel economy
- ✔ Check Engine Light with codes such as P069E, P0230, or U0109
The Smart Solution: A Pre-Programmed 2008-2009 Avalanche FPCM
Don’t waste time and money with a trip to the dealership for programming. We take care of the most critical step for you. Before this module ships, we will flash it with the latest GM-approved software specifically for your vehicle’s Vehicle Identification Number (VIN). This ensures perfect communication with your truck’s powertrain control module (PCM) and eliminates software-related bugs that may have existed in the original part. You receive a component that is truly ready to install right out of the box, restoring your vehicle’s factory performance and reliability.
A Straightforward Guide to Installation
Replacing the FPCM is a job most DIYers can handle in their own driveway with basic hand tools. The 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 inside of the driver-side frame rail. You may need to lower the spare tire for better access.
- Disconnect and Remove: Carefully unplug the electrical connectors. Then, remove the bolts or nuts securing the old module to the frame. These can be corroded, so a little penetrating oil might help.
- Install the New Module: Mount your new, pre-programmed FPCM in the same location. It’s a good practice to clean the mounting surface and apply a bit of dielectric grease to the connectors to prevent future corrosion.
- Reconnect and Test: Plug in the electrical connectors, reconnect the battery terminal, and cycle the key a few times before starting the engine to prime the fuel system. Your truck should now start and run smoothly.

Frequently Asked Questions
Why do you need my VIN?
Your vehicle’s VIN is required to load the correct, vehicle-specific software from GM onto the module. This ensures it communicates perfectly with your truck’s computer systems, just like a part from the dealer.
Is this part difficult to install?
No, for most DIYers with basic tools, this is a straightforward replacement. The module is typically located on the frame rail and is accessible once you lower the spare tire. Since it comes pre-programmed, no special computer tools are needed.
Will this fix a P069E code?
Yes, the diagnostic trouble code P069E (Fuel Pump Control Module Commanded On) is one of the most common codes indicating a failed FPCM. Replacing the module is the standard repair for this issue.
What happens if I install it without programming?
An unprogrammed FPCM will not work. It will not be able to communicate with the vehicle’s main computer (PCM/ECM), and your fuel pump will not operate, resulting in a no-start condition. Our pre-programming service solves this entirely.
Is this a new or used part?
This is a high-quality, tested replacement part that is guaranteed to perform to OEM specifications. We load it with brand new GM software specific to your VIN.
