Restore Your Vehicle’s Performance and Reliability
Is your 2009 Buick Enclave or other GM vehicle cranking but not starting? Experiencing sudden stalls, hesitation during acceleration, or a persistent Check Engine Light? These are classic signs of a failing Fuel Pump Control Module (FPCM), a critical component that regulates voltage to your fuel pump. When it fails, it can leave you stranded without warning. This isn’t just an inconvenience; it’s a significant disruption to your day. In my 20+ years in the shop, I’ve seen countless drivers frustrated by these exact symptoms, often leading to expensive diagnostic fees and dealership programming costs.

We flash it with the latest GM factory software updates, ensuring optimal performance and eliminating the need for a costly trip to the dealer. This process corrects common software glitches and ensures your new module communicates perfectly with your vehicle’s computer system, restoring proper fuel pressure and engine performance. For anyone tackling this repair, getting a pre-programmed 2009 Enclave Fuel Pump Module is the smartest way to get back on the road quickly and confidently.
From the Diagnostic Bay: The Silverado That Wouldn’t Start
A 2008 Silverado 1500 was towed into my bay last month. The owner said it died at a stoplight and wouldn’t restart. It would crank all day long, but never fire. My first check is always the basics: spark, air, and fuel. A quick check with a fuel pressure gauge at the rail showed zero PSI. My next step wasn’t to condemn the fuel pump—that’s a common mistake. Instead, I checked for power at the pump connector and found nothing. This pointed me directly to the FPCM, which on these trucks is notoriously mounted on the frame rail, exposed to water, salt, and vibration. A quick scan confirmed it: code U0109, Lost Communication with Fuel Pump Control Module. We replaced it with a pre-programmed unit just like this one, and the truck fired up on the first try. The customer was back on the road in under an hour, avoiding a much more expensive pump replacement.
Is Your Vehicle Showing These Telltale Signs?
A failing FPCM can manifest in several ways. If you’re noticing any of the following, this module is the likely culprit. Early diagnosis can save you from being stranded.
- âś” Engine cranks but will not start
- âś” Vehicle stalls unexpectedly, especially while driving
- âś” Hesitation or stumbling during acceleration
- âś” Reduced engine power and poor fuel economy
- âś” Check Engine Light is illuminated
- âś” Common Diagnostic Trouble Codes (DTCs) stored, such as P069E, P0230, or U0109
A Straightforward Guide to Installation
Replacing the 2009 Enclave Fuel Pump Module is a job most DIY enthusiasts can handle with basic tools. Because our module comes pre-programmed, you skip the most difficult step. Always consult a vehicle-specific repair manual, but here is a general guide:
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the Module: Find the old FPCM. On many GM trucks and SUVs (like the Tahoe, Suburban, Silverado), it’s mounted on the driver’s side frame rail, often near the spare tire. On vehicles like the Enclave or Traverse, it may be on a rear crossmember.
- Disconnect and Remove: Carefully unplug the electrical connector(s). Then, remove the bolts or nuts securing the module to the frame. These can sometimes be corroded, so a little penetrating oil might be helpful.
- Install the New Module: Mount your new, pre-programmed FPCM in the same location. It’s often recommended to apply a dielectric grease to the new module’s backing plate to help prevent corrosion between it and the frame.
- Connect and Secure: Securely fasten the module with the original hardware. Plug the electrical connector back in, ensuring it clicks into place.
- Final Steps: Reconnect the negative battery terminal. Turn the key to the ‘On’ position for 10-15 seconds to allow the system to prime, then start the vehicle to confirm the repair.

Frequently Asked Questions
What does a Fuel Pump Control Module (FPCM) do?
The FPCM, also known as a Fuel System Control Module (FSCM), acts like a smart relay for your fuel pump. It receives commands from the Engine Control Module (ECM) and precisely regulates the voltage sent to the fuel pump. This ensures the engine gets the exact amount of fuel it needs under all driving conditions, improving efficiency and performance.
Why do I need to provide my VIN?
Your vehicle’s VIN is essential because it allows us to program the module with the correct, most current GM software specifically for your vehicle’s configuration (engine, transmission, emissions, etc.). This plug-and-play programming ensures the module works perfectly right out of the box, with no additional flashing required.
Is this a difficult part to replace myself?
For most DIYers with basic mechanical skills, this is a very manageable job. The module is typically located on the vehicle’s frame and held in place by a few bolts. The main challenge is usually accessing it. Since our module comes pre-programmed, you eliminate the need for specialized electronic tools, making it a simple bolt-off, bolt-on repair.
What happens if I install a module that isn’t programmed?
An unprogrammed module will not work. The vehicle will likely not start, and it will set communication error codes (like U0109). The FPCM must be able to communicate with the ECM and other vehicle systems, which is only possible after it has been correctly programmed with your VIN.
