Restore Your Truck’s Performance and Reliability
Is your 2008-2009 Chevrolet Avalanche 1500 experiencing frustrating issues like stalling, hesitation on acceleration, or a dreaded no-start condition? Before you suspect the in-tank fuel pump, the culprit is often the Fuel Pump Control Module (FPCM). This vital component, also known as a Fuel System Control Module (FSCM), regulates the voltage sent to the fuel pump, ensuring precise fuel pressure for optimal engine performance. When it fails, it can leave you stranded and chasing a difficult diagnosis. This module is the definitive solution, arriving at your door pre-programmed with the latest GM software specifically for your vehicle.
Case Study: A Tricky Diagnosis
I remember a 2008 Silverado that came into my shop with a classic intermittent stalling complaint. The owner had already replaced the fuel pump, but the problem persisted. No check engine light was on, but a scan with a professional tool revealed a stored history code: P069E (Fuel Pump Control Module Commanded OFF). A visual inspection under the truck revealed the issue. The original FPCM, mounted to the driver-side frame rail, was heavily corroded from years of exposure to road salt and moisture. This corrosion caused an internal short, leading to the erratic behavior. Replacing the module with a pre-programmed unit like this one solved the problem instantly, saving the customer from another expensive misdiagnosis.
Common Symptoms of a Failing FPCM
If your vehicle is exhibiting any of the following signs, a faulty Fuel Pump Control Module is a likely cause. A failing module can often trigger diagnostic trouble codes (DTCs) that can confirm your diagnosis.
- ✔ Vehicle cranks but will not start
- ✔ Engine stalls unexpectedly, especially under load
- ✔ Hesitation or stumbling during acceleration
- ✔ Noticeable loss of engine power and poor performance
- ✔ Reduced fuel economy
- ✔ Check Engine Light with codes such as P069E, P0230, or U0109
A Straightforward Guide to Installation
One of the greatest benefits of this module is that it arrives ready to install, with no dealer programming required. This turns a potentially complex job into a manageable DIY task for anyone with basic tools. This guide is for a typical GM truck installation; your specific vehicle may have minor variations.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- Locate the Module: On most GM trucks and SUVs like the Avalanche, the FPCM is mounted on the driver-side frame rail, typically near the spare tire.
- Disconnect: Carefully unplug the electrical connectors from the old module. Press the release tabs firmly to avoid breaking them.
- Unbolt the Old Module: Remove the bolts or nuts securing the old FPCM to the frame. It may be corroded, so a little penetrating oil can help.
- Install the New Module: Bolt your new, pre-programmed 2008-2009 Avalanche Fuel Pump Module into place.
- Reconnect and Finalize: Plug the electrical connectors securely into the new module. Reconnect your battery terminal. Your installation is complete, and your truck is ready to go!

Frequently Asked Questions
Do I really need to provide my VIN?
Yes, providing your Vehicle Identification Number (VIN) is essential. We use your VIN to load the correct, vehicle-specific GM software and the latest updates onto the module before shipping. This ensures it works perfectly with your truck right out of the box.
What happens if I install a module that isn’t programmed?
An unprogrammed module will not work. The vehicle’s computer systems will not recognize it, and the fuel pump will not operate. This will result in a no-start condition, and you would then need to have the vehicle towed to a dealer for expensive programming.
Where is this 2008-2009 Avalanche Fuel Pump Module located?
On the 2008-2009 Avalanche and similar GM trucks, the FPCM is typically mounted on the outside of the driver-side frame rail, often above the spare tire area. Its location exposes it to the elements, which is a common reason for its failure.
Is this a common part to fail?
Yes, FPCM failure is a well-documented issue on many GM trucks and SUVs from this era. Due to its mounting location, it is susceptible to water intrusion and corrosion, which damages the internal electronics over time.
Will this fix a P069E code?
In the vast majority of cases, yes. The Diagnostic Trouble Code P069E is one of the most common indicators of a failed Fuel Pump Control Module. Replacing the faulty module with this pre-programmed unit is the standard, correct repair for that code.
