Restore Peak Performance and Reliability to Your GM Vehicle
Is your truck or SUV experiencing frustrating and unpredictable issues like stalling, hesitation on acceleration, or a complete no-start condition? Before you consider replacing the entire fuel pump, the culprit is often a faulty Fuel Pump Control Module (FPCM), also known as a Fuel System Control Module (FSCM). This critical component regulates the voltage sent to your fuel pump, and when it fails, it can mimic the symptoms of a bad pump, leading to costly misdiagnoses. I’ve seen it countless times in the shop: a vehicle comes in on a tow truck, and the owner is convinced they need a new pump, only for us to find the FPCM is the real problem.
This module, part number 25854536, is the definitive solution. We take the guesswork and hassle out of the repair by pre-programming the module to your vehicle’s specific Vehicle Identification Number (VIN). This means it arrives at your door ready for a direct, plug-and-play installation, with the latest software updates from GM already loaded. You get a reliable fix without the expensive trip to the dealership for programming.
A Technician’s Notebook: The Intermittent Stall Case
A customer brought in their 2008 Chevy Tahoe complaining of a very tricky issue: it would run fine for days, then suddenly stall at a stoplight and refuse to restart for 10-15 minutes. They had already replaced the fuel filter with no change. We scanned for codes and found a P069E (Fuel Pump Control Module Commanded OFF). Instead of jumping to the fuel pump, we focused on the 2009 Outlook Fuel Pump Module‘s equivalent on the Tahoe. These modules are often mounted on the frame rail, exposed to water, salt, and road debris. Sure enough, we found the module’s casing was compromised, allowing moisture to corrode the internal circuit board. A new, VIN-programmed module fixed the problem permanently. It’s a classic failure pattern for these vehicles.

- âś” Check Engine Light with codes like P069E, P0230, or U0109
- âś” “Service Fuel System” message on the dash
A Straightforward Guide to Installation
Replacing your FPCM is a job most DIYers can handle with basic tools. Because we program it for you, no special electronic tools are needed.
- Safety First: Disconnect the negative terminal from your vehicle’s battery.
- Locate the Module: On most GM trucks and SUVs (like the Silverado, Tahoe, Yukon), the FPCM is mounted on the driver’s side frame rail, often near the spare tire. On other models like the Traverse or Acadia, it may be on a rear crossmember. A quick search for your specific model will confirm its location.
- Disconnect and Remove: Unplug the electrical connector(s) by depressing the locking tab. Then, remove the bolts or nuts holding the old module to the frame.
- Install the New Module: Bolt the new, pre-programmed FPCM into place. Ensure it is securely fastened.
- Reconnect: Plug the electrical connector(s) firmly into the new module until they click.
- Final Step: Reconnect the negative battery terminal. Start the vehicle to confirm the repair is successful.

Frequently Asked Questions
Why do you need my VIN?
Your vehicle’s VIN allows us to load the exact, correct software and calibrations from GM for your specific model, year, and options. This ensures perfect communication between the FPCM and other vehicle systems, making the part truly plug-and-play.
What does the Fuel Pump Control Module do?
The FPCM is a small computer that receives commands from the main Engine Control Module (ECM) and precisely controls the speed of the fuel pump. This modern system is more efficient than older systems that ran the pump at full speed all the time.
Can I install this myself?
Absolutely. Because we handle the programming, this becomes a simple bolt-off, bolt-on repair. You do not need any special diagnostic scanners or programming tools, which saves you a significant amount of money compared to a dealership visit.
Where is the FPCM located on my 2009 Saturn Outlook?
On the Saturn Outlook, as well as its platform mates like the Acadia and Traverse, the FPCM is typically mounted to the rear crossmember, accessible from underneath the vehicle.
Is this part compatible with other part numbers?
Yes, this module is a direct replacement for several part numbers, including 25854536, 13501024, 20759945, 25785013, and others listed in the description. It covers a wide range of GM vehicles.
What happens if I install a module that isn’t programmed?
An unprogrammed module will not work correctly. Your vehicle will likely not start, or it may run very poorly and set communication error codes. Our pre-programming service eliminates this problem entirely.
