Is Your GM Truck or SUV Stalling or Refusing to Start? The FPCM is the Likely Culprit.
If you’re experiencing frustrating issues like engine stalling, a no-start condition, or hesitation in your 2007-2009 GM vehicle, the problem may not be the fuel pump itself. A more common and often misdiagnosed point of failure is the Fuel Pump Control Module (FPCM), also known as the Fuel System Control Module (FSCM). This critical electronic component is responsible for precisely managing the voltage supplied to your in-tank fuel pump, ensuring your engine receives the exact amount of fuel it needs under all driving conditions. When this module fails, it can lead to a variety of drivability problems that can leave you stranded.
This replacement FPCM is the definitive solution to get your vehicle back on the road reliably. We take the hassle and expense out of the repair by pre-programming the module to your vehicle’s specific Vehicle Identification Number (VIN) before it ships. This means you receive a true plug-and-play part, eliminating the need for a costly trip to the dealership for programming with a specialized scan tool. Simply install the module, and your vehicle’s fuel system will be restored to factory specifications.
From the Diagnostic Bay
We recently had a 2008 Sierra 1500 towed in. The owner was at his wit’s end; he had already replaced the in-tank fuel pump himself, but the truck still wouldn’t start. After checking his work, we connected our diagnostic scanner and immediately saw a U0109 code—Lost Communication with Fuel Pump Control Module. A quick voltage test at the module, which is mounted on the driver-side frame rail, confirmed it had power and ground but was completely unresponsive. These modules are in a vulnerable location, constantly exposed to road salt, water, and debris, which leads to internal corrosion and failure. We installed one of our pre-programmed modules, and the truck fired up on the first crank. It’s a classic example where diagnosing the complete fuel system, not just the pump, saved time and prevented replacing good parts.
Common Symptoms of a Failing GM Fuel Pump Control Module
- ✔ Engine stalls unexpectedly, often while driving or coming to a stop.
- ✔ Vehicle cranks but will not start, or experiences extended cranking times.
- ✔ Noticeable hesitation or stumbling during acceleration.
- ✔ Illumination of the Check Engine Light with trouble codes such as P069E, P0230, P0606, or U0109.
- ✔ Reduced engine power and a significant drop in fuel economy.
- ✔ The engine may run rough or misfire due to inconsistent fuel pressure.
The Importance of VIN-Specific Programming
Modern GM vehicles utilize a complex network of modules that communicate with each other. The FPCM must be calibrated with the correct software for your vehicle’s specific engine, drivetrain, and emissions package. Installing a used module from another vehicle or a new, un-programmed unit will not work. The vehicle’s security system will prevent it from starting, and communication errors will occur. Our professional programming service uses the latest GM updates to load your VIN-specific data onto the module, ensuring seamless integration and flawless performance right out of the box. This is not a generic flash; it is the precise calibration your vehicle requires.

Frequently Asked Questions
How do I provide my vehicle’s VIN?
After you complete your purchase, simply reply to your order confirmation email with your 17-digit VIN. We cannot ship your part until we receive this information, as the programming is a critical step in the process.
Is this part difficult to install?
For most trucks and SUVs like the Sierra, Silverado, and Tahoe, the module is located on the driver’s side frame rail near the spare tire. It is typically held on by two bolts. The installation involves disconnecting the battery, unplugging the electrical connector, removing the old module, and bolting the new one in its place. Since it comes pre-programmed, no further steps are needed. Installation is straightforward for anyone with basic mechanical skills.
Will this module fit vehicles other than the Sierra Denali?
Yes, absolutely. This FPCM fits a wide variety of 2007-2009 GM trucks, vans, and SUVs, including the Chevrolet Silverado, Tahoe, Suburban, Avalanche, Express, GMC Sierra, Yukon, Savana, Cadillac Escalade, Hummer H2, and many more. Please refer to the detailed fitment list to confirm compatibility.
What happens if I don’t provide a VIN?
The module will not function correctly without being programmed to a specific VIN. It will prevent the vehicle from starting and may set multiple communication trouble codes. We require your VIN to ensure you receive a part that works perfectly upon installation.
Does this part fix the common P069E trouble code?
Yes. The Diagnostic Trouble Code (DTC) P069E, which reads “Fuel Pump Control Module Commanded OFF,” is one of the most common indicators of a failed FPCM. In the vast majority of cases, replacing the module with this pre-programmed unit is the correct and final repair for this code.
