Restore Your Enclave’s Performance with a VIN-Programmed Fuel Module
Is your 2010-2012 Buick Enclave experiencing frustrating issues like engine stalling, a no-start condition, or a persistent Check Engine Light? Before you consider replacing the entire fuel pump, the problem often lies with a failing Fuel System Control Module (FSCM). This vital component regulates the voltage sent to your fuel pump, ensuring your engine receives the precise amount of fuel it needs. When it fails, it can cause a host of drivability problems that can leave you stranded.
This is a direct-replacement Fuel System Control Module for your GM vehicle, arriving at your door fully programmed with the latest GM software. We take your vehicle’s VIN and flash the module specifically for it, eliminating the need for an expensive trip to the dealership for programming. This makes the repair process faster, more affordable, and accessible for both professional technicians and DIY enthusiasts.
From the Diagnostic Bay
I remember a 2011 Yukon that came into my shop with a classic “crank, no start” complaint. The owner had already replaced the fuel pump himself, but the problem persisted. He was frustrated and out several hundred dollars. After hooking up my scan tool, I saw DTC P069E – Fuel Pump Control Module Requested MIL Illumination. A quick check of the FSCM connector showed power and ground, but the module wasn’t commanding the pump. A new, pre-programmed FSCM like this one had the truck running perfectly in under 15 minutes. It’s a prime example of how diagnosing the FSCM first can save significant time and money.
Is Your Vehicle Showing These Symptoms?
- ✔ Engine cranks but will not start
- ✔ Stalling, especially under load or when coming to a stop
- ✔ Rough idle or hesitation during acceleration
- ✔ Reduced engine power and poor fuel economy
- ✔ Check Engine Light with codes such as P069E, P0230, or U0109
A Straightforward Guide to Installation
- ✔ Safety First: Disconnect the negative terminal from your vehicle’s battery.
- ✔ Locate the Module: On the Buick Enclave, Acadia, and Traverse, the FSCM is typically mounted to the rear subframe crossmember. On trucks and SUVs, it’s often on the driver-side frame rail, near the spare tire.
- ✔ Disconnect and Remove: Unplug the electrical connector(s) from the old module. Then, remove the bolts or nuts securing it to the frame or crossmember.
- ✔ Install the New Module: Mount the new, pre-programmed FSCM in the same location and secure it with the original hardware.
- ✔ Final Connections: Plug the electrical connector(s) firmly into the new module and reconnect the negative battery terminal. The vehicle is now ready to start.

Frequently Asked Questions
What is a Fuel System Control Module (FSCM)?
The FSCM, sometimes called a fuel pump driver module, is a small computer that controls the power going to your vehicle’s electric fuel pump. It ensures the pump runs at the correct speed to deliver the right amount of fuel pressure for optimal engine performance and efficiency.
Does this module really come ready to install?
Yes. This is the key benefit of our service. We use your Vehicle Identification Number (VIN) to flash the module with the latest, vehicle-specific software from GM before we ship it. It is a true plug-and-play solution, no dealer programming is required.
How do I provide my VIN?
After you complete your purchase, simply send us a message with your 17-digit VIN. We cannot program and ship your module without it, so please provide it promptly to avoid delays.
Is this a reliable fix for a P069E code?
In our experience, a faulty FSCM is the most common cause of a P069E diagnostic trouble code. While you should always perform a complete diagnosis, replacing the FSCM with this pre-programmed unit is a very common and effective solution for that specific code.
Could my fuel pump be bad instead of the module?
It’s possible, but the FSCM is a frequent point of failure and is generally easier and less expensive to replace. We often recommend checking or replacing the FSCM first, especially if you have communication codes or a P069E code, before committing to the more involved job of replacing the in-tank fuel pump.
