Restore Your Vehicle’s Starting and Running Performance
Is your 2009 Buick Enclave or other GM vehicle suddenly refusing to start, stalling in traffic, or hesitating under acceleration? Before you condemn the fuel pump itself, the issue often lies with its electronic controller. The Fuel Pump Control Module (FPCM), also known as a Fuel System Control Module (FSCM), is the brain that tells your fuel pump how much pressure to deliver. When it fails, you’re left with an unreliable vehicle and a major headache. In my 20+ years of diagnostics, I’ve seen countless owners replace a perfectly good fuel pump, only to find the real problem was this module all along.
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We take the guesswork and extra expense out of the repair by pre-programming this module to your vehicle’s specific Vehicle Identification Number (VIN). This means it arrives at your door with the latest, most stable software from GM, eliminating the need for a costly trip to the dealership for programming. This is the most efficient way to get your truck or SUV back to factory-spec operation.
Solving Common Fuel Delivery Problems with a 2009 Enclave Fuel Pump Module
A faulty FPCM can create a wide range of frustrating, intermittent issues. Because this module directly controls the voltage sent to the fuel pump, its failure can mimic a weak or dying pump. By ensuring the pump receives precise commands, a new, properly functioning 2009 Enclave Fuel Pump Module restores the stable fuel pressure your engine needs for consistent performance, reliable starting, and optimal fuel economy. Don’t let a small electronic component keep your vehicle off the road.
Case Study: The Tahoe That Wouldn’t Cooperate
A customer brought in their ’08 Tahoe with a classic crank-no-start condition. They had already replaced the fuel pump, but the problem persisted. We checked for fuel pressure at the rail and got nothing. Instead of just throwing another pump at it, we hooked up the scan tool. We found DTC U0109 (Lost Communication with Fuel Pump Control Module). A quick check of the wiring confirmed it was okay, pointing directly to a failed FPCM. We installed one of our VIN-programmed modules, and the truck fired up on the first try. The customer saved hundreds by avoiding a misdiagnosis and a second fuel pump installation.
Is Your Vehicle Showing These Symptoms?
- ✔ Engine cranks but will not start
- ✔ Vehicle stalls unexpectedly, especially when warm
- ✔ Noticeable hesitation or stumbling during acceleration
- ✔ Reduced engine power and poor performance
- ✔ Check Engine Light with codes like P069E, P0230, or U0109
- ✔ A whining noise from the fuel pump area that is inconsistent
A Straightforward Guide to Installation
- ✔ Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- ✔ Locate the Module: On most GM trucks and SUVs, the FPCM is mounted to the frame rail or a rear crossmember, often near the spare tire. On vehicles like the Vue or Traverse, the location may differ. Always consult a service manual for your specific model if you’re unsure.
- ✔ Disconnect and Remove: Unplug the electrical connectors from the old module. Be gentle with the locking tabs, as they can become brittle over time. Then, remove the bolts or nuts securing the module to the frame.
- ✔ Install the New Module: Mount your new, pre-programmed FPCM in the same location and secure it with the original hardware.
- ✔ Reconnect and Finalize: Plug the electrical connectors firmly into the new module. Reconnect the negative battery terminal. Turn the key to the ‘On’ position for 10 seconds before starting to allow the system to prime. Start the engine and check for proper operation.

Frequently Asked Questions About the 2009 Enclave Fuel Pump Module
Frequently Asked Questions
Do I really need to provide my VIN?
Yes, providing your VIN is essential. We use it to load the correct, vehicle-specific GM software and the latest updates onto the module before shipping. This ensures it communicates perfectly with your vehicle’s other computers right out of the box.
What happens if I install this without it being programmed?
An unprogrammed module will not work. The vehicle’s computer systems will not recognize it, and your engine will not start or run correctly. Our pre-programming service solves this entire problem for you.
Is this a difficult part to replace myself?
For most DIYers with basic hand tools, this is a very manageable job. The module is typically in an accessible location on the vehicle’s frame. The most important part is ensuring the electrical connectors are seated properly.
How do I know if the module is bad and not the fuel pump?
While symptoms can be similar, a key diagnostic step is checking for trouble codes like U0109 (lost communication) or P069E (commanded performance issue). If you have access to a scan tool, this can confirm the FPCM is the source of the fault. Intermittent stalling is also a very common sign of a failing module.
Will this work for other part numbers?
Yes, this module is a direct replacement for several part numbers, including 13501024, 20759945, 25866052, and others listed in the description. It provides the same function and fitment.
