Is Your GM Truck or SUV Stalling, Hesitating, or Refusing to Start?
If you’re experiencing frustrating fuel delivery problems with your 2008-2009 Sierra Denali, Silverado, Tahoe, or other compatible GM vehicle, a failing Fuel Pump Control Module (FPCM) is a very common cause. This critical component, also known as a Fuel System Control Module (FSCM), regulates the voltage sent to your fuel pump. When it fails, it can leave you stranded with a vehicle that cranks but won’t start, stalls unexpectedly, or suffers from poor engine performance. Don’t replace the entire fuel pump assembly until you’ve checked this module—it’s often the real source of the problem.
From the Diagnostic Bay
We had a 2009 Silverado 1500 towed in that was a classic “crank, no start.” The owner had already replaced the in-tank fuel pump himself, but the issue persisted. He was frustrated and out a few hundred dollars. We hooked up our scanner and immediately saw diagnostic trouble code P069E – “Fuel Pump Control Module Commanded OFF.” Instead of checking fuel pressure at the rail, we went straight to the FPCM mounted on the driver-side frame rail. It was heavily corroded from road salt and moisture. We installed one of our pre-programmed modules, cleared the code, and the truck fired up on the first try. It’s a textbook case of how diagnosing the control side of the circuit first can save you time and money.
Symptoms of a Failing Fuel Pump Control Module
- ✔ Engine cranks but will not start.
- ✔ Vehicle stalls while driving, especially under load.
- ✔ Hesitation or stumbling during acceleration.
- ✔ Reduced engine power and poor fuel economy.
- ✔ Check Engine Light (CEL) is illuminated on the dash.
- ✔ Diagnostic Trouble Codes (DTCs) such as P069E, P0230, or U0109 are stored in the computer.
The Plug-and-Play Solution: A Pre-Programmed Sierra Denali Fuel Pump Module
The biggest hurdle when replacing an FPCM is the need for expensive programming at a dealership. This module eliminates that step entirely. We take care of the programming for you before we ship. Using the Vehicle Identification Number (VIN) you provide, we flash the module with the latest, most stable software updates directly from GM. This ensures perfect communication with your vehicle’s other computers, like the ECM, and corrects potential software glitches that may have existed in the original factory programming. The result is a true plug-and-play part. Simply mount it, connect the electrical plugs, and you’re back on the road.
Installation and Location
On most compatible trucks and SUVs like the Sierra, Silverado, and Yukon, you’ll find the FPCM mounted on the driver-side frame rail, typically above the spare tire. It’s exposed to the elements, which is why corrosion and water intrusion are the leading causes of failure. Installation is straightforward for anyone with basic mechanical skills. It involves disconnecting the battery, unplugging the two electrical connectors, and removing a few bolts. Since our module is pre-programmed, no further steps are required.
Guaranteed Compatibility
This module is a direct replacement for a wide range of GM vehicles and is compatible with numerous original part numbers, including: 13501024, 15213110, 20759945, 20850907, 25785013, 25854536, 25866052, and 25967325. Please see the detailed fitment list to confirm this part is correct for your exact make and model. Providing your VIN during checkout is mandatory to ensure we load the correct software for your specific vehicle configuration.
Frequently Asked Questions
Why do you need my vehicle’s VIN?
Your VIN (Vehicle Identification Number) is essential because it allows us to program the Fuel Pump Control Module with the exact software and calibrations for your specific truck or SUV. This includes details about the engine, transmission, and other systems. This process makes the part a true plug-and-play solution, saving you a trip to the dealership for expensive programming.
What happens if I install this module without programming?
An unprogrammed module will not work. The FPCM must be able to communicate with your vehicle’s Engine Control Module (ECM) and other systems. Without the correct VIN-specific software, your vehicle will likely not start and may set communication-related trouble codes. Our pre-programming service handles this for you.
Is this part difficult to install?
For most DIY mechanics, the installation is relatively simple. The module is typically located on the vehicle’s frame rail and held on by a few bolts. The main challenge can be accessing it, especially if there is rust. However, since the programming is already done, the electrical part of the job is just unplugging the old module and plugging in the new one.
Will this fix a P069E trouble code?
The code P069E (Fuel Pump Control Module Commanded OFF) is a very strong indicator that the FPCM has failed or has an internal fault. While you should always confirm the wiring and connectors are in good condition, replacing the FPCM is the most common and effective fix for this specific code.
Is this a new or used part?
This is a high-quality, fully tested component guaranteed to restore the function of your vehicle’s fuel system. Each module is inspected and programmed with the latest GM software to ensure reliability and performance that meets or exceeds the original factory part.
