Is your 2009 Buick Enclave or other GM vehicle experiencing frustrating and unpredictable fuel-related problems? Issues like engine stalling, difficulty starting, rough idling, or a sudden loss of power can often be traced back to a single, critical component: the Fuel Pump Control Module (FPCM), also known as a Fuel System Control Module (FSCM). This module is the brain behind your vehicle’s fuel delivery system, and when it fails, it can leave you stranded. This listing is for a direct-replacement FPCM, part number 25785013, that arrives at your door pre-programmed to your vehicle’s specific VIN, ensuring a seamless, plug-and-play installation.
From the Diagnostic Bay
We recently had a 2009 GMC Sierra 1500 towed in with a classic no-start condition. The owner had already replaced the in-tank fuel pump himself, assuming it was the culprit, but the truck still wouldn’t fire up. He was frustrated and had spent money on a part he didn’t need. After a quick scan, we saw no communication with the FPCM. We checked power and ground at the module—both were good. The module itself, located on the frame rail, had simply failed internally. We installed a VIN-programmed module, and the truck started instantly. This is a common scenario; always check the FPCM before condemning the more expensive and labor-intensive fuel pump.
Solving Fuel Issues with the 2009 Enclave Fuel Module
The FPCM is responsible for precisely controlling the voltage sent to the fuel pump. Unlike older systems that ran the pump at full speed all the time, modern returnless fuel systems use this module to vary the pump’s speed based on engine demand. This provides better efficiency and longevity for the pump. However, the constant electrical load and its typical mounting location on the vehicle’s frame expose the FPCM to harsh conditions—vibration, moisture, and road salt—leading to premature failure. Our solution provides you with a reliable module loaded with the latest GM software updates specific to your vehicle, correcting known issues and restoring proper function.
Common Symptoms of a Failing FPCM
- ✔ Engine cranks but will not start.
- ✔ Stalling, especially under load or when coming to a stop.
- ✔ Hesitation or stumbling during acceleration.
- ✔ Reduced engine power and poor fuel economy.
- ✔ A check engine light with diagnostic trouble codes (DTCs) such as P069E, P0230, or U0109.
- ✔ Inconsistent fuel pressure readings.
Replacing your faulty FPCM with our pre-programmed unit is the most effective way to resolve these issues and restore your vehicle’s reliability. The critical advantage of our service is the VIN-specific programming. Without this step, a new module will not communicate with your vehicle’s other computers, and the engine will not start. We handle this for you, saving you a costly trip to the dealership for programming and diagnostics. Simply provide your VIN after purchase, and we’ll ship a module that is ready for installation right out of the box.
This module is a direct fit for a wide range of General Motors trucks and SUVs. Please verify your part number or consult the compatibility list. This part is a compatible replacement for the following part numbers: 13501024, 15213110, 20759945, 20850907, 25785013, 25854536, 25866052, and 25967325.
Frequently Asked Questions
What does a Fuel Pump Control Module do?
The FPCM regulates the voltage and current sent to your vehicle’s electric fuel pump. Based on signals from the Engine Control Module (ECM), it adjusts the pump’s speed to deliver the precise amount of fuel the engine needs at any given moment, improving efficiency and performance.
Why do I need to provide my VIN?
Modern vehicles require electronic modules to be programmed with the vehicle’s specific Vehicle Identification Number (VIN) to function. This programming ensures the FPCM can communicate correctly with the ECM and other systems. We perform this service for you so the part is ready to install upon arrival, saving you a trip to the dealer.
Is this module difficult to install?
For most supported vehicles, the FPCM is mounted on the frame rail or a crossmember and is accessible from underneath. Installation typically involves disconnecting the battery, unplugging the electrical connector, and removing a few bolts. It is a straightforward job for a DIY mechanic with basic tools. No special programming tools are needed since we handle that part.
What happens if I install a module that isn’t programmed?
If you install a new, unprogrammed FPCM, your vehicle will not start. The module will not be recognized by the vehicle’s security and engine management systems, and it will not activate the fuel pump. Our pre-programming service eliminates this problem entirely.
How can I be sure the 2009 Enclave Fuel Module is my problem?
While the symptoms listed are strong indicators, proper diagnosis is key. A mechanic can check for specific trouble codes (like U0109 for lost communication with FPCM), and test for power and ground at the module’s connector. If power and ground are present but the fuel pump isn’t running or receiving voltage, the FPCM is the most likely cause.
