Is Your Truck Stalling, Hesitating, or Refusing to Start?
If your 2008-2009 Chevrolet Avalanche, or another compatible GM vehicle, is experiencing frustrating fuel delivery problems, a failing Fuel Pump Control Module (FPCM) is a very common cause. This critical component, also known as a Fuel System Control Module (FSCM), is responsible for precisely managing the voltage sent to your fuel pump. When it fails, it can leave you stranded with a vehicle that cranks but won’t start, or cause dangerous stalling and hesitation while driving. Don’t settle for guesswork; restore your vehicle’s reliability with our direct-fit, professionally programmed FPCM.
Expert Pro Tip
Before replacing your FPCM, take a moment to inspect the electrical connector and wiring harness. These modules are often mounted on the frame rail, exposing them to road salt, water, and debris. Corrosion on the pins or damaged wires can mimic the symptoms of a failed module. A quick visual inspection can save you from replacing a perfectly good part. Always apply a small amount of dielectric grease to the connector pins upon installation to protect against future moisture intrusion.
Diagnosing a Faulty 2008-2009 Avalanche Fuel Pump Module
The FPCM on these GM trucks and SUVs is a known failure point. The original designs were susceptible to internal circuit board issues and corrosion, leading to a host of performance problems. If you’re experiencing any of the following, your FPCM is the likely culprit.
Common Symptoms of FPCM Failure:
- ✔ Engine cranks but will not start
- ✔ Stalling, especially under load or when coming to a stop
- ✔ Rough idle or engine hesitation during acceleration
- ✔ Reduced engine power and poor fuel economy
- ✔ Check Engine Light with specific diagnostic trouble codes (DTCs)
- ✔ Common DTCs include P069E, P0230, P0606, and U0109 (Lost Communication with FPCM)
- ✔ A buzzing or whining noise from the fuel pump, or no noise at all
The Plug-and-Play Solution: Programmed to Your VIN
Replacing an FPCM isn’t as simple as just swapping the part. A new module from a dealership or parts store comes blank and requires expensive, specialized equipment to program it to your vehicle’s specific Vehicle Identification Number (VIN). Without proper programming, the module will not communicate with your vehicle’s other computers, and your engine will not start. Our service eliminates this costly and inconvenient step. We take the hassle out of the repair by professionally flashing this module with the latest, most stable GM-approved software for your exact vehicle. All you need to do is provide your VIN during checkout, and we handle the rest. The module you receive will be a true plug-and-play component, ready for immediate installation.
This module is a direct replacement for a wide range of original equipment part numbers, including: 13501024, 15213110, 20759945, 20850907, 25785013, 25854536, 25866052, and 25967325. By ordering from us, you get a part that is not only matched to your vehicle but also contains the most recent software updates from the manufacturer, addressing potential issues present in the original programming.
Frequently Asked Questions
Why do I need to provide my VIN?
Your vehicle’s VIN (Vehicle Identification Number) is essential because the Fuel Pump Control Module must be programmed with software specific to your truck’s engine, transmission, and other options. This programming ensures the FPCM communicates correctly with the Engine Control Module (ECM) and delivers the precise fuel pressure required for optimal performance and efficiency. Without VIN-specific programming, the vehicle will not run.
Is this part difficult to install?
For most of the listed GM trucks and SUVs, the FPCM is located on the driver’s side frame rail, typically near the spare tire. Installation is straightforward for someone with basic mechanical skills. It usually involves disconnecting the battery, unplugging the electrical connector, and removing a few bolts. Since our module comes pre-programmed, no further steps are needed after installation. It is a true plug-and-play repair.
Will this fix my Check Engine Light for code P069E?
Yes, the diagnostic trouble code P069E (Fuel Pump Control Module Commanded OFF) is one of the most common indicators of a failed FPCM. While you should always confirm the diagnosis, replacing a faulty FPCM with our pre-programmed unit is the definitive fix for this code in the vast majority of cases.
What happens if I install a module that isn’t programmed?
An unprogrammed, or ‘blank’, module will not work. Your vehicle’s computers operate on a network, and the FPCM must be recognized on that network to function. An unprogrammed module will result in a no-start condition and will likely set communication-related trouble codes, such as U0109. You would then need to have the vehicle towed to a dealership or qualified shop with GM programming tools to have the module flashed, adding significant cost and inconvenience to the repair.
Is this a new or used part?
This is a high-quality, tested, and verified used OEM component. Each module is inspected and then programmed with the latest GM software for your specific VIN, ensuring it functions to the original manufacturer’s specifications and provides a reliable, long-lasting repair.
