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 frustrating check engine light can bring your day to a grinding halt. For many owners of 2007-2009 GM vehicles, these perplexing issues often point to a single, critical component: the Fuel Pump Control Module (FPCM), also known as the Fuel System Control Module (FSCM). This module is the brain behind your fuel delivery system, and when it fails, it can mimic a wide range of other problems, leading to confusion and costly misdiagnoses. This replacement module, part number 25967325, is the definitive solution to restore your vehicle’s reliability and performance.
The Critical Role of a Functioning 2009 Enclave Fuel Pump Module
In modern vehicles like your Buick Enclave, the fuel system is no longer a simple on/off switch. The FPCM is a sophisticated computer that communicates with the Engine Control Module (ECM) to precisely manage fuel pressure. It does this by varying the voltage sent to the in-tank fuel pump. This demand-based system improves efficiency and prolongs the life of the fuel pump. However, due to its typical mounting location on the frame rail or crossmember, the FPCM is exposed to harsh conditions—road salt, water, mud, and vibrations—which can lead to internal corrosion and electronic failure. A failing module can’t properly regulate the fuel pump, leading to either too much or, more commonly, too little fuel pressure for the engine’s needs.
From the Diagnostic Bay
We had a 2008 Chevy Tahoe come into the shop on a tow truck. The customer said it died on the highway and wouldn’t restart. The initial thought was a bad fuel pump, a common failure. We checked fuel pressure at the rail and got zero. But something felt off. Instead of just ordering a new pump, we hooked up our diagnostic scanner and tried to command the fuel pump on. Nothing. We then went directly to the FPCM connector on the frame rail. We found we had power and ground going into the module, but no voltage coming out to the pump. A quick tap on the module’s casing with a screwdriver handle, and we heard the pump prime for a second! The module was internally corroded and failing intermittently. We replaced it with a pre-programmed unit like this one, and the Tahoe fired right up. It saved the customer hundreds of dollars by avoiding an unnecessary fuel pump replacement.
Common Symptoms of a Faulty FPCM
- ✔ Engine Stalling: The vehicle may stall unexpectedly while driving or at idle due to a sudden loss of fuel pressure.
- ✔ No-Start Condition: The engine will crank over but will not start because the fuel pump is not being activated.
- ✔ Hesitation or Stumbling: During acceleration, the vehicle may hesitate or stumble as the module fails to command the necessary increase in fuel flow.
- ✔ Reduced Engine Power: The vehicle may enter a ‘limp mode’ or display a “Reduced Engine Power” message on the dash.
- ✔ Check Engine Light: A failing FPCM will often trigger specific Diagnostic Trouble Codes (DTCs). Common codes include P069E, P0230, P025A, and U0109 (Loss of Communication with Fuel Pump Control Module).
- ✔ Loud Fuel Pump Whine: In some cases, a failing module can send erratic voltage, causing the fuel pump to run at maximum speed continuously, resulting in a noticeable whine from the fuel tank area.
The “Plug & Play” Advantage: Pre-Programmed for Your VIN
Replacing an FPCM isn’t as simple as just swapping the part. These modules are vehicle-specific and must be programmed with the correct software and calibration files to communicate with your vehicle’s other computers. Installing a blank or incorrect module will result in a no-start condition and communication error codes. Our service eliminates this critical and often expensive step. When you purchase this module, you provide us with your Vehicle Identification Number (VIN). We then flash the module with the latest, most stable GM-certified software specifically for your vehicle. This means when the part arrives, it is a true plug-and-play solution. No need for an expensive trip to the dealership or a specialized shop for programming. Just install it, connect it, and turn the key.

Frequently Asked Questions
Do I need to get this module programmed by a dealer?
No. The main benefit of our service is that we program the module for you before it ships. Simply provide your vehicle’s VIN at checkout, and the module will arrive ready to install, saving you time and money.
Where is the FPCM located on my truck or SUV?
The location varies slightly by model. On most GM trucks and full-size SUVs (Tahoe, Silverado, Sierra, etc.), it is mounted to the driver’s side frame rail, near the spare tire. On crossovers (Enclave, Acadia, Traverse), it’s often on a rear crossmember. Always consult a service manual for your specific vehicle to confirm the exact location before beginning work.
Is this the same as the fuel pump?
No, they are two separate components. The fuel pump is the mechanical pump located inside your fuel tank. This part, the Fuel Pump Control Module (FPCM), is the electronic computer that tells the fuel pump how fast to run. This module is often the cause of a “no fuel pressure” issue, not the pump itself.
What happens if I install a module that isn’t programmed?
An unprogrammed or incorrectly programmed FPCM will not be able to communicate with your vehicle’s main computer (ECM). This will result in a no-start condition, and you will likely get a U0109 communication code. Our pre-programming service prevents this issue entirely.
My original part number isn’t 25967325, but it’s on your list. Will this work?
Yes. Part number 25967325 is an updated GM part that supersedes several older numbers, including 13501024, 20759945, and others listed in the description. As long as your original part number is on our compatibility list, this module is the correct, updated replacement for your vehicle.
