Is Your GM Truck or SUV Stalling or Refusing to Start?
There’s nothing more frustrating than a vehicle that cranks but won’t run, or one that stalls unexpectedly in traffic. If your 2008-2009 Chevrolet Avalanche, Silverado, Tahoe, or other compatible GM vehicle is experiencing these issues, a faulty Fuel Pump Control Module (FPCM) is the most common culprit. This component, part number 20850907, is the brain behind your fuel delivery system, and when it fails, it can leave you stranded. We offer a reliable, plug-and-play solution to get you back on the road with confidence.
From the Diagnostic Bay
We had a 2008 GMC Sierra 1500 towed in that was driving the owner crazy. It would start fine cold, but after 20 minutes of driving, it would sputter and die. It would crank but not restart until it cooled down. The owner had already replaced the fuel pump, thinking that was the issue, but the problem persisted. A quick scan revealed a P069E trouble code: “Fuel Pump Control Module Commanded OFF.” We went straight to the FPCM on the frame rail, and sure enough, it was corroded and failing when it got hot. We installed one of our VIN-programmed modules, and the truck ran perfectly. The customer could have saved hundreds of dollars by diagnosing the FPCM first.
The Critical Role of the Fuel Pump Control Module
Unlike older systems that used a simple relay to run the fuel pump at full speed all the time, modern GM vehicles use an FPCM for precise control. This module receives data from the Engine Control Module (ECM) and adjusts the voltage sent to the in-tank fuel pump. By varying the pump’s speed based on engine load, acceleration, and other factors, the FPCM ensures optimal fuel pressure, improves fuel efficiency, and extends the life of the fuel pump. However, its typical mounting location on the vehicle’s frame rail exposes it to moisture, salt, and vibration, leading to premature failure.
Symptoms of a Failing FPCM
- ✔ Engine cranks but will not start.
- ✔ Vehicle stalls unexpectedly, often after it has warmed up.
- ✔ Stumbling, hesitation, or sputtering during acceleration.
- ✔ Noticeable loss of engine power.
- ✔ An active Check Engine Light with diagnostic trouble code (DTC) P069E.
- ✔ Inconsistent or low fuel pressure readings.
- ✔ A buzzing or whining noise from the fuel pump that is erratic.
Why Choose Our Pre-Programmed 2008-2009 Avalanche 1500 Fuel Pump Module?
Replacing the FPCM isn’t just about swapping the part. A new module from the dealership is a blank slate; it must be professionally programmed with special equipment to communicate with your vehicle’s specific Vehicle Identification Number (VIN). This means an expensive trip to the dealer and additional labor costs. Our solution eliminates that step entirely. We take the hassle and extra cost out of the repair by programming the module for you before it ships. Simply provide us with your VIN during checkout, and you’ll receive a part that is 100% ready for installation. It’s a true plug-and-play fix.
This module is a direct replacement for a wide range of GM vehicles and supersedes multiple original part numbers, including: 13501024, 15213110, 20759945, 20850907, 25785013, 25854536, 25866052, and 25967325. Restore your vehicle’s performance and reliability with a component that is correctly configured for its systems.
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 part ready to install right out of the box, saving you a trip to the dealership and additional programming fees.
Where is the FPCM located on my 2009 Tahoe or Sierra?
On most compatible GM trucks and SUVs like the Tahoe, Suburban, Sierra, and Silverado, the Fuel Pump Control Module is typically mounted on the driver-side frame rail, often above or near the spare tire. It’s a small, black box with an electrical connector and is held in place by a few bolts.
What happens if I install this without programming?
An unprogrammed module will not communicate correctly with your vehicle’s other computers. This will almost certainly result in a no-start condition and may set various communication-related trouble codes. Our pre-programming service ensures this will not be an issue.
Is this a new or used part?
This is a high-quality, fully tested genuine GM component that has been verified for correct operation and programmed with the latest software updates available for your vehicle. It is guaranteed to restore function to your fuel system.
What is the difference between an FPCM and a fuel pump relay?
A traditional fuel pump relay is a simple on/off switch. An FPCM is a sophisticated computer that precisely controls the speed of the fuel pump by varying its voltage. This provides better fuel efficiency and control compared to a simple relay system.
