Is Your Truck Stalling, Hesitating, or Refusing to Start?
If you’re experiencing erratic engine behavior, poor fuel economy, or a dreaded no-start condition in your 2008-2009 GM truck or SUV, a failing Fuel Pump Control Module (FPCM) is a highly probable cause. This critical 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 leave you stranded by either starving the engine of fuel or, in some cases, running the pump constantly and burning it out. Don’t let a faulty module compromise your vehicle’s reliability. This is the direct, VIN-programmed solution you need to restore proper fuel delivery and get back on the road with confidence.
From the Diagnostic Bay
We had a 2008 Sierra 1500 come into the shop on a tow truck. The owner had already replaced the in-tank fuel pump himself, but the truck still wouldn’t start. He was frustrated and out a few hundred dollars. After hooking up our scan tool, we immediately saw the classic trouble code: P069E – Fuel Pump Control Module Commanded OFF. A quick check of the FPCM, located on the driver’s side frame rail, showed significant corrosion on the housing and connectors—a very common issue. We installed a new, pre-programmed module, cleared the codes, and the truck fired right up. The customer could have saved himself a lot of time and money by diagnosing the module first. It’s often the silent culprit behind fuel delivery problems.
Symptoms of a Failing Fuel Pump Control Module
A failing FPCM can manifest in several ways, often being misdiagnosed as a bad fuel pump. If your vehicle is exhibiting any of the following symptoms, it’s time to inspect your module:
- ✔ Engine Stalling: The engine may stall unexpectedly while driving or at idle due to inconsistent fuel pressure.
- ✔ No-Start Condition: The most common symptom is a crank-no-start situation where the engine turns over but never fires up because the fuel pump isn’t being activated.
- ✔ Engine Hesitation or Stumbling: During acceleration, the truck may hesitate or feel like it’s losing power as the module struggles to command the correct fuel flow.
- ✔ Check Engine Light: Diagnostic Trouble Codes (DTCs) such as P069E, P025A, or P064A are strong indicators of an FPCM-related fault.
- ✔ Reduced Power Mode: The vehicle’s computer may trigger a “Reduced Power” message on the dash to protect the engine from potential damage.
- ✔ Whining from the Fuel Tank: An audible whine from the fuel pump running continuously, even with the key off, points to a shorted or failed module.
The Superior Solution: A VIN-Programmed Sierra Denali Fuel Pump Module
Simply replacing the hardware isn’t enough for modern vehicles. This Sierra Denali Fuel Pump Module must be programmed with your vehicle’s specific Vehicle Identification Number (VIN) to communicate correctly with the Engine Control Module (ECM) and other vehicle systems. Our service eliminates the most significant hassle of this repair: the trip to the dealership. We handle the programming for you.
When you purchase from us, you get a part that is flashed with the latest stable software release from GM, tailored specifically to your truck. This ensures optimal performance, fuel efficiency, and seamless integration. It’s a true plug-and-play solution that saves you the time, expense, and headache of dealer-level programming or calibration.
Installation and Compatibility
This FPCM is a direct-fit replacement for the original part, ensuring an easy installation. On most trucks and SUVs like the Sierra, Silverado, and Tahoe, the module is located on the driver’s side frame rail, making it accessible for a DIY repair. Simply disconnect the battery, unplug the electrical connectors, unbolt the old module, and install the new one in its place.
This module is compatible with a wide range of GM vehicles and replaces numerous original part numbers, including:
Compatible Part Numbers: 13501024, 15213110, 20759945, 20850907, 25785013, 25854536, 25866052, 25967325
Frequently Asked Questions
Why do I need to provide my VIN?
Your vehicle’s VIN is essential because it allows us to program the Fuel Pump Control Module with the exact software and calibrations specific to your truck’s engine, transmission, and other options. This ensures the module works perfectly out of the box without requiring a trip to a dealer for expensive programming.
Is this part difficult to install?
For most DIY mechanics with basic tools, this is a straightforward installation. The module is typically mounted on the vehicle’s frame rail and is held in place by a few bolts. The process involves disconnecting the battery, unplugging the old module, and bolting the new one in place. Since we pre-program it, no special electronic tools are needed.
Will this fix a P069E trouble code?
Yes, the DTC P069E (Fuel Pump Control Module Commanded OFF) is one of the most common codes indicating a failed FPCM. Replacing the module with this pre-programmed unit is the correct and most effective solution for this specific code, assuming the related wiring is intact.
What does a Fuel Pump Control Module do?
The FPCM is a small computer that receives commands from the Engine Control Module (ECM) and then regulates the voltage sent to the electric fuel pump. This allows for precise control over fuel pressure and flow, which improves fuel efficiency and engine performance compared to older systems that simply ran the pump at full speed all the time.
Is this a plug-and-play part?
Absolutely. Because we program the module to your specific VIN before shipping, it becomes a true plug-and-play part. Once installed, your vehicle’s computer system will recognize it, and it will function correctly without any further calibration or setup required.
