Is Your GM Truck or SUV Stalling, Hesitating, or Refusing to Start?
A sudden loss of power, an engine that cranks but won’t catch, or a persistent Check Engine Light can be incredibly frustrating. These are classic symptoms of a failing fuel system component, and on many 2007-2009 GM vehicles, the culprit is often the Fuel Pump Control Module (FPCM), also known as a Fuel System Control Module (FSCM). This isn’t just a simple relay; it’s a sophisticated computer that precisely manages the fuel pump’s speed and voltage. When it fails, it can leave you stranded without warning.
The Critical Role of a Programmed GM Fuel Pump Control Module
The FPCM is the brain behind your fuel pump. It receives commands from the main Engine Control Module (ECM) and adjusts the fuel pump’s output based on engine load, speed, and other critical factors. This variable-pressure system is more efficient and extends the life of the fuel pump compared to older, constant-run systems. However, this complexity also introduces a critical point of failure. A faulty GM Fuel Pump Control Module can cause a range of issues, from intermittent drivability problems to a complete no-start condition, often accompanied by diagnostic trouble codes like P069E (Fuel Pump Control Module Commanded On), P0230, or P025A.
From the Diagnostic Bay
We had a 2008 Silverado 1500 in the shop that was a real head-scratcher for the owner. He had already replaced the fuel pump twice, but the truck would still intermittently stall and refuse to restart for hours. The codes were pointing to the fuel pump circuit. Upon inspection, we found the original FPCM mounted on the driver’s side frame rail, covered in road grime and corrosion. The module’s casing had been compromised by moisture, causing internal failure. We installed one of our VIN-programmed modules, and the truck has run flawlessly ever since. It’s a textbook example of why you must check the FPCM before condemning the pump itself.
Common Symptoms of a Failing FPCM
- ✔ Engine cranks but will not start
- ✔ Vehicle stalls unexpectedly while driving
- ✔ Loss of power or hesitation during acceleration
- ✔ Rough or unstable idle
- ✔ Check Engine Light illuminated with fuel system codes (e.g., P069E)
- ✔ A noticeable whine from the fuel pump that changes erratically
Your Plug-and-Play Solution is Here
Don’t let a faulty module keep your vehicle down. This FPCM is a direct replacement for part number 25866052 and a host of other compatible numbers. The most significant benefit we offer is our professional programming service. When you order, you provide us with your vehicle’s VIN. We then flash the module with the latest GM software specific to your vehicle. This means the part arrives at your door ready for a true plug-and-play installation. You can avoid the time, expense, and hassle of a dealership visit for programming, turning a complex repair into a straightforward job you can do at home.
Installation is Straightforward
On most trucks and SUVs like the Silverado, Sierra, Tahoe, and Escalade, the module is located on the driver-side frame rail, near the spare tire. On other vehicles like the Saturn Vue or GMC Acadia, it may be in a different location, such as the rear engine compartment or on a rear crossmember. Always disconnect the negative battery terminal before beginning work. Simply unbolt the old module, disconnect the electrical connector, and install the new one in its place. Reconnect the battery, and you’re ready to go.
This module is a direct replacement for the following part numbers: 13501024, 15213110, 20759945, 20850907, 25785013, 25854536, 25866052, 25967325.
Frequently Asked Questions
What does a Fuel Pump Control Module do?
The FPCM regulates the voltage sent to the electric fuel pump. Instead of running the pump at full speed all the time, the FPCM adjusts its speed based on the engine’s real-time fuel demand, improving efficiency and prolonging the life of the fuel pump.
Do I need to program this module?
No. We handle the programming for you before shipment. You must provide your vehicle’s 17-digit VIN during checkout so we can load the correct software. This makes the module ready to install right out of the box.
Where is this module located on my vehicle?
The location varies. On most GM full-size trucks and SUVs (Silverado, Sierra, Tahoe, Yukon, etc.), it’s mounted on the driver’s side frame rail. On other models like the Acadia, Traverse, or Vue, it can be on a rear crossmember or in the engine compartment. A quick search for your specific model will confirm the location.
How do I know if my FPCM is bad?
Common signs include the engine cranking but not starting, stalling, hesitation, and a Check Engine Light with codes like P069E. A technician can perform a diagnostic check to confirm the FPCM is not communicating or is sending incorrect voltage to the fuel pump.
What happens if I don’t provide my VIN?
We cannot ship the module without your VIN. The programming is essential for the part to function correctly in your vehicle. Your order will be placed on hold until the VIN is provided to ensure you receive a perfectly matched part.
