Is Your GM Truck or SUV Stalling or Refusing to Start?
There are few things more frustrating than turning the key in your 2008-2009 GM vehicle and hearing the engine crank but never start. You might also be experiencing sudden stalling at stoplights, hesitation when you accelerate, or a persistent Check Engine Light on your dash. These are classic signs that your vehicle’s fuel delivery system is compromised, and a very common culprit is a failed Fuel Pump Control Module (FPCM), also known as a Fuel System Control Module (FSCM).
This module is the brain behind your fuel pump. Unlike older systems that ran the fuel pump at full power all the time, your vehicle uses this sophisticated controller to precisely manage the voltage sent to the pump. It ensures the engine receives the exact amount of fuel it needs for optimal performance and efficiency. When the FPCM fails, this critical link is broken, leading to a range of drivability issues that can leave you stranded.
Common Symptoms of a Failing FPCM
- ✔ Engine cranks but will not start
- ✔ Vehicle stalls unexpectedly, often when coming to a stop or under load
- ✔ Severe hesitation or sputtering during acceleration
- ✔ Noticeable loss of engine power and poor performance
- ✔ Reduced fuel economy
- ✔ Check Engine Light is on with fuel-related Diagnostic Trouble Codes (DTCs) such as P069E, P0230, P0087, or the communication code U0109.
From the Diagnostic Bay
We recently had a 2009 GMC Sierra 1500 towed in with a classic ‘crank, no start’ condition. The owner, a capable DIYer, had already spent a weekend replacing the in-tank fuel pump assembly, assuming it was the problem. Unfortunately, the new pump didn’t change a thing. When we connected our diagnostic tool, we immediately saw code U0109 – Lost Communication with Fuel Pump Control Module. A quick look under the truck at the driver’s side frame rail told the whole story. The original FPCM was covered in white, chalky corrosion from years of exposure to road salt and moisture. The aluminum housing had failed, allowing water to destroy the internal circuit board. A new, pre-programmed module had the truck running perfectly in under 15 minutes. Always check this module before condemning the fuel pump; it can save you hundreds of dollars and a lot of unnecessary work.
Why Choose Our Programmed 2008-2009 Avalanche 1500 Fuel Pump Module?
Replacing the FPCM isn’t just a matter of swapping the part. A new module from a dealership is a blank slate; it must be professionally programmed with specialized GM software (SPS) to function in your specific vehicle. Without this programming, the module cannot communicate with your Engine Control Module (ECM), and your truck will not start. This step typically requires a tow to the dealer and an additional, expensive programming fee.
We eliminate that hassle entirely. This is a complete, ready-to-install solution. When you purchase this module, you simply provide us with your vehicle’s 17-digit VIN. Our technicians will then use that information to flash the module with the latest, most stable GM-approved software and vehicle-specific calibrations. It arrives at your door ready for a true plug-and-play installation, saving you time, money, and the headache of a dealership visit.
Installation and Compatibility
Installation is straightforward for anyone with basic mechanical skills. The FPCM is typically located on the driver’s side frame rail, near the spare tire. The process involves disconnecting the battery, unplugging the electrical connector, removing a few bolts, and installing the new unit. This module is a direct replacement for a wide range of GM trucks and SUVs, ensuring a perfect fit and restored function.
This module is a direct replacement for the following part numbers: 13501024, 15213110, 20759945, 20850907, 25785013, 25854536, 25866052, 25967325.
By ordering our pre-programmed 2008-2009 Avalanche 1500 Fuel Pump Module, you’re not just buying a part; you’re buying a complete, guaranteed solution to get your vehicle back on the road reliably and affordably.
Frequently Asked Questions
Do I need to get this module programmed?
No. The main benefit of our service is that we program the module to your vehicle’s specific VIN before we ship it. This makes the installation process simple and straightforward, with no need for a trip to the dealership or special tools.
Where is the FPCM located on my vehicle?
On most GM trucks and full-size SUVs like the Silverado, Sierra, Tahoe, and Avalanche, the FPCM is mounted on the driver’s side frame rail, often above or near the spare tire. On other models, it may be on a rear crossmember. It is typically exposed to the elements, which is a primary cause of its failure.
What happens if I install a module without programming?
An unprogrammed module will not work. The vehicle’s computer systems will not recognize it, and as a result, the fuel pump will not activate. Your vehicle will crank but will not start.
What information do you need from me for programming?
After you place your order, we will need your 17-digit Vehicle Identification Number (VIN). You can typically find this on your vehicle’s registration, insurance card, or on a plate on the driver’s side of the dashboard visible through the windshield.
Could my in-tank fuel pump be the problem instead?
While a fuel pump can fail, the FPCM is a very common point of failure on these specific GM models due to its exposed location. A good diagnostic step is to check for the U0109 trouble code or to test for voltage at the fuel pump connector while an assistant cranks the engine. No voltage often points directly to a bad FPCM.
Is this part compatible with other part numbers?
Yes, this module is a direct replacement for several part numbers, including 13501024, 15213110, 20759945, 20850907, 25785013, 25866052, and 25967325. If your original module has any of these numbers, this part will work for you.
