Is Your GM Truck or SUV Stalling, Hesitating, or Refusing to Start?
A sudden loss of power, an engine that cranks but won’t start, or an intermittent stalling issue can be incredibly frustrating and leave you stranded. In many 2007-2009 GM vehicles, these problems point directly to a failing Fuel Pump Control Module (FPCM), also known as a Fuel System Control Module (FSCM). This vital component is responsible for precisely managing the voltage sent to your fuel pump, ensuring your engine receives the exact amount of fuel it needs under all driving conditions. When it fails, the entire fuel delivery system is compromised, leading to a host of performance issues and diagnostic trouble codes like P069E, P0230, or U0109.
From the Diagnostic Bay
We had a 2008 Silverado 1500 towed in that was a classic ‘crank-no-start.’ The owner had already replaced the fuel pump, thinking that was the obvious culprit, but the problem persisted. A quick scan showed a P069E code: ‘Fuel Pump Control Module Commanded OFF.’ We checked the wiring and found it was fine. The issue? The original FPCM, mounted on the frame rail, had succumbed to years of exposure to road salt and moisture, causing internal corrosion. We installed one of our pre-programmed modules, and the truck fired up on the first try. The customer was thrilled to have his truck back without an expensive trip to the dealership for programming.

Frequently Asked Questions
Do I need to get this module programmed by a dealer?
No. This Fuel Pump Control Module comes fully programmed to your vehicle’s VIN before it is shipped. It is ready for installation right out of the box, saving you time and the expense of dealer programming.
Where is the FPCM located on my 2008 Avalanche?
On most GM trucks and SUVs from this era, including the 2008-2009 Avalanche, the FPCM is typically mounted to the driver’s side frame rail, often near the spare tire. It’s exposed to the elements, which is a common reason for its failure.
What is the difference between an FPCM and a fuel pump?
The fuel pump is the physical pump inside your gas tank that moves fuel. The Fuel Pump Control Module (FPCM) is the computer that tells the fuel pump how fast to run. A bad FPCM can make a perfectly good fuel pump seem faulty.
Will this fit vehicles other than the Avalanche?
Yes, absolutely. This module fits a wide variety of 2007-2009 GM vehicles, including the Silverado, Sierra, Tahoe, Yukon, Escalade, Hummer H2, and many others. Please check the detailed fitment list on this page to confirm compatibility with your specific model.
What information do you need from me for programming?
After you complete your purchase, you will need to provide us with your vehicle’s 17-digit VIN. We use this to load the correct GM-certified software and calibration files onto the module for your specific vehicle configuration.
