Is Your GM Truck or SUV Stalling, Hesitating, or Refusing to Start?
If you’re experiencing erratic engine behavior, a sudden loss of power, or a frustrating no-start condition in your 2009 Buick Enclave or other compatible GM vehicle, a failing Fuel Pump Control Module (FPCM) is a very likely culprit. 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 continuously and burning it out. Don’t let a small electronic box cause a major headache. This is the direct-fit, pre-programmed solution you need to restore your vehicle’s reliability and performance.
From the Diagnostic Bay
We had a 2008 Silverado 1500 towed in with a classic “cranks but won’t start” complaint. The owner had already replaced the in-tank fuel pump himself, assuming it was the obvious fix, but the truck still wouldn’t fire up. After confirming he had no fuel pressure at the rail, we checked the FPCM fuse—it was good. A quick scan revealed diagnostic trouble code P069E: “Fuel Pump Control Module Commanded OFF.” Instead of throwing more parts at it, we inspected the FPCM mounted on the frame rail. It was heavily corroded from years of exposure to road salt and moisture. We installed one of our VIN-programmed modules, cleared the codes, and the truck started instantly. The customer could have saved himself hours of work and the cost of a fuel pump by diagnosing the FPCM first. It’s a common and often overlooked point of failure.
Common Failure Symptoms of a Bad FPCM
- ✔ Check Engine Light with codes like P069E, P0230, P025A, or U0109.
- ✔ Engine cranks but will not start.
- ✔ Stalling, especially under load or when coming to a stop.
- ✔ Severe engine hesitation or stumbling during acceleration.
- ✔ Rough idle or inconsistent engine performance.
- ✔ A noticeable loss of power and poor fuel economy.
- ✔ In rare cases, a humming noise from the fuel pump running after the vehicle is off.
The Critical Role of the 2009 Enclave Fuel Pump Module
In modern vehicles with returnless fuel systems, the FPCM is the brain behind fuel delivery. It receives commands from the Engine Control Module (ECM) based on engine load, speed, and other factors. It then modulates the voltage to the fuel pump, spinning it at the precise speed needed to deliver the exact amount of fuel required. This is far more efficient than older systems that ran the pump at full speed all the time. However, this constant work, combined with their often-exposed mounting location on the vehicle’s frame, makes them susceptible to failure from heat, vibration, and corrosion.
The Plug-and-Play Solution: Pre-Programmed for Your VIN
Replacing an FPCM isn’t just a simple swap. A new module from the dealership is a blank slate; it must be programmed with specialized tools to communicate with your vehicle’s specific VIN and software configuration. This typically means an expensive trip to the dealer for installation and programming. We eliminate that step entirely. When you purchase this module, you provide us with your vehicle’s VIN. Our technicians will then flash the unit with the latest, most stable software updates directly from GM. The module you receive will be 100% ready for installation. Simply bolt it on, plug it in, and turn the key. No extra costs, no appointments, and no towing fees.
This FPCM is a direct replacement for a wide range of popular GM trucks and SUVs, including the Chevrolet Silverado, Tahoe, Suburban, GMC Sierra, Yukon, Cadillac Escalade, and more. It is compatible with multiple original part numbers, including 25854536, 13501024, 15213110, 20759945, 20850907, 25785013, 25866052, and 25967325, ensuring a perfect match for your application.
Frequently Asked Questions
Do I need to have this module programmed?
No. We handle all the programming for you before the part is shipped. You must provide your vehicle’s 17-digit VIN during checkout or by sending us a message. The module will arrive ready to install, saving you a trip to the dealership.
Where is the FPCM located on my vehicle?
Location varies by model. On most GM trucks and large SUVs (Silverado, Sierra, Tahoe, Escalade), it’s mounted on the driver’s side frame rail, near the spare tire. On crossovers like the Enclave, Acadia, and Traverse, it’s typically found on or near the rear subframe/crossmember. Always consult a service manual for your specific vehicle to confirm the location.
How do I provide my VIN?
You can enter your VIN in the notes section during the checkout process or send it to us through a direct message after placing your order. Please double-check the VIN for accuracy to ensure correct programming.
Is this part compatible with other part numbers?
Yes, this module is a direct replacement for several part numbers, including 13501024, 15213110, 20759945, 20850907, 25785013, 25866052, and 25967325. If your original module has any of these numbers, this part will work for you.
What happens if I install a module that isn’t programmed to my VIN?
An unprogrammed or incorrectly programmed FPCM will not communicate properly with your vehicle’s other computers. This will typically result in a no-start condition and may set communication-related trouble codes. Our pre-programming service ensures this will not happen.
