Is Your GM Truck or SUV Stalling, Hesitating, or Refusing to Start?
A sudden loss of power, difficulty starting, or engine stalling are more than just annoyances—they’re often signs of a failing fuel system component. Before you assume the worst and replace the entire fuel pump, the real culprit could be a faulty Fuel Pump Control Module (FPCM). This vital electronic 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 starve your engine of fuel, leading to a host of performance issues and diagnostic trouble codes.
This replacement GM Fuel Control Module is the definitive solution for restoring your vehicle’s fuel delivery system to factory specifications. It’s a direct-fit replacement for part number 20850907 and is compatible with a wide range of popular GM trucks and SUVs, including the Sierra, Silverado, Tahoe, and Escalade. The most significant advantage? We program the module to your vehicle’s specific Vehicle Identification Number (VIN) before it ships. This means no expensive trips to the dealership, no special tools required for programming—just a straightforward, plug-and-play installation to get you back on the road quickly and reliably.
From the Diagnostic Bay
We had a 2009 Sierra 1500 towed in with a classic ‘crank, no-start’ condition. The owner had already replaced the in-tank fuel pump himself, but the problem persisted. He was frustrated and out a few hundred dollars. We hooked up our diagnostic scanner and immediately saw code P069E – ‘Fuel Pump Control Module Commanded OFF.’ Instead of throwing more parts at it, we inspected the FPCM located on the driver-side frame rail. It was heavily corroded from years of exposure to road salt and moisture. A new, programmed module had the truck running perfectly in under 30 minutes. It’s a powerful reminder to always diagnose the control side of the circuit before condemning a major component like the fuel pump.
Symptoms of a Failing GM Fuel Control Module
If your vehicle is exhibiting any of the following symptoms, a faulty FPCM is a likely cause. A failing module can mimic a bad fuel pump, so proper diagnosis is key. Look out for:
- ✔ Engine Stalling: The engine may stall unexpectedly while driving or at idle due to inconsistent fuel pressure.
- ✔ No-Start Condition: The engine cranks over but will not start because the fuel pump is not being activated.
- ✔ Hesitation on Acceleration: The vehicle may stumble or hesitate when you press the gas pedal, as the fuel pump can’t deliver the required volume of fuel.
- ✔ Reduced Engine Power: Your truck or SUV may feel sluggish and lack its normal power.
- ✔ Check Engine Light: Common trouble codes associated with a bad FPCM include P069E, P0230, P025A, and U0109 (Lost Communication with FPCM).
- ✔ Loud Fuel Pump Whine: An FPCM sending incorrect voltage can sometimes cause the fuel pump to run at full speed continuously, creating an audible whine.
The Critical Advantage: Pre-Programmed for Your Vehicle
Modern vehicle electronics are complex and require precise software to function. This Fuel Pump Control Module is not a one-size-fits-all part. It must be calibrated to your vehicle’s specific systems. Our service eliminates the biggest installation hurdle by programming the module with the latest GM-certified software using the VIN you provide. This ensures seamless communication with your vehicle’s Engine Control Module (ECM) and other systems, guaranteeing correct fuel pressure and flow under all driving conditions. You receive a part that is truly ready to install right out of the box.
Guaranteed Fitment & Compatibility
This module is a direct replacement for a wide array of GM vehicles, ensuring a perfect fit and function. It is compatible with original equipment part numbers: 13501024, 15213110, 20759945, 20850907, 25785013, 25854536, 25866052, and 25967325. It fits models like the 2009 GMC Canyon, 2007-2009 Sierra & Silverado 1500, 2008-2009 Tahoe, Yukon, Suburban, Escalade, and many others. Please verify the part number and check the detailed fitment list to confirm compatibility with your specific vehicle.
Frequently Asked Questions
Do I need to get this module programmed?
No. The main benefit of our service is that we program the module for you before shipping. Simply provide your VIN during checkout, and the module will arrive ready for a plug-and-play installation, saving you a trip to the dealer.
Where is the FPCM located on my vehicle?
On most GM trucks and large SUVs from this era (like the Silverado, Sierra, and Tahoe), the FPCM is typically mounted on the driver-side frame rail, near the spare tire. On other models, it can be on a rear crossmember or in the engine compartment. It is exposed to the elements, which is a primary reason for its failure.
What happens if I don’t provide my VIN?
We cannot ship the module without your vehicle’s VIN. The programming is essential for the part to function correctly in your vehicle. The order will be held until we receive the VIN from you.
How do I know if my FPCM is bad and not the fuel pump?
While symptoms can be similar, a good diagnostic step is to check for power at the fuel pump connector while a helper cranks the engine. If there’s no voltage, the problem is likely upstream with the FPCM or its wiring. Additionally, specific diagnostic trouble codes like P069E or U0109 point directly to the FPCM system.
Is this a difficult part to replace?
For someone with basic mechanical skills, this is a relatively straightforward replacement. It typically involves disconnecting the negative battery terminal, unplugging the electrical connector, and removing a few bolts holding the module to the frame. Since our module is pre-programmed, no software or computer work is needed post-installation.
