Is Your Truck Stalling, Hesitating, or Refusing to Start?
If you’re experiencing frustrating fuel delivery issues with your GM truck or SUV, a faulty Fuel Pump Control Module (FPCM), also known as a Fuel System Control Module (FSCM), is a very common culprit. This critical component is responsible for precisely managing the voltage sent to your fuel pump, ensuring your engine receives the correct amount of fuel under all driving conditions. When it fails, it can leave you stranded with a vehicle that won’t start, or cause dangerous stalling and power loss while driving. This module is the definitive solution to restore your vehicle’s performance and reliability.
From the Diagnostic Bay
We had a 2008 Sierra 1500 in the shop that was driving the owner crazy. It would stall randomly at red lights and sometimes wouldn’t start after being parked for a short time. He had already replaced the in-tank fuel pump, but the problem persisted. After hooking up our diagnostic scanner, we noticed the fuel rail pressure was dropping erratically. A quick inspection under the truck revealed the cause: the original FPCM, mounted on the frame rail, was heavily corroded from years of exposure to road salt and moisture. The corrosion had compromised the internal electronics, causing it to overheat and fail intermittently. We installed a new, pre-programmed module, and the truck ran perfectly. This is a story we see time and time again with these vehicles.
Symptoms of a Failing Fuel Pump Control Module
- ✔ Engine stalling unexpectedly, especially when coming to a stop or under load.
- ✔ Difficulty starting the engine, or a crank-no-start condition.
- ✔ Engine hesitation, sputtering, or stumbling during acceleration.
- ✔ Noticeable loss of engine power and poor performance.
- ✔ An illuminated Check Engine Light with diagnostic trouble codes (DTCs) such as P069E, P0230, P025A, or U0109.
- ✔ A fuel gauge that reads empty even with a full tank of gas.
Why Choose Our 2007-2009 Sierra 1500 Fuel Pump Control Module?
This isn’t just a replacement part; it’s a complete, ready-to-install solution. The biggest hurdle in replacing an FPCM is the need for expensive programming at a dealership. We eliminate that step entirely. Using the Vehicle Identification Number (VIN) you provide, we program the module with the latest, most stable software updates directly from GM before it ever leaves our facility. This ensures perfect compatibility and corrects potential issues that may have existed with the original factory software.
This module is a direct-fit replacement for a wide range of GM vehicles and is compatible with numerous original part numbers, including 13501024, 15213110, 20759945, 25785013, 25854536, and more. Installation is straightforward for any DIY mechanic with basic tools. The module is typically located on the driver’s side frame rail, making it accessible without removing major components. Simply disconnect the battery, unbolt the old module, plug in your new pre-programmed unit, and you’re ready to get back on the road with confidence.
Frequently Asked Questions
Do I need to take this module to a dealer for programming?
Absolutely not. The main benefit of our service is that we program the module to your vehicle’s specific VIN before we ship it to you. This makes the installation a true plug-and-play process, saving you time and the high cost of dealership programming.
Where is the FPCM located on my 2008 Sierra 1500?
On most 2007-2009 GM trucks and SUVs like the Sierra, Silverado, Tahoe, and Yukon, the Fuel Pump Control Module is mounted on the driver’s side frame rail cross-member, often near the spare tire. It’s exposed to the elements, which is a primary reason for its high failure rate.
What’s the difference between the FPCM and the fuel pump itself?
The fuel pump is a mechanical device located inside your fuel tank that physically pumps fuel to the engine. The FPCM is the electronic ‘brain’ that tells the fuel pump how fast to run. The FPCM receives commands from the main Engine Control Module (ECM) and then regulates the voltage to the pump accordingly.
Will this part fix a P069E check engine light code?
The DTC P069E (Fuel Pump Control Module Commanded OFF) is one of the most common codes indicating a failed FPCM. While this module is the most frequent cause and solution for this code, we always recommend confirming the diagnosis. Check for wiring issues or other potential faults before replacing any parts.
How do I provide my VIN for programming?
After you complete your purchase, you will need to send us your 17-digit VIN. You can typically add it as a note during checkout or send it to us in a message referencing your order number. We cannot ship the module until we have your VIN to program it correctly.
