Restore Your Acadia’s Fuel Delivery and Performance
Is your 2010-2012 GMC Acadia experiencing frustrating issues like engine stalling, a no-start condition, or a persistent “Reduced Engine Power” message on the dash? Before you condemn the fuel pump, the real culprit is often a faulty Fuel System Control Module (FSCM). As a technician with over 20 years of experience, I’ve seen this exact scenario countless times. These modules, often mounted on the frame or rear crossmember, are exposed to the elements, leading to internal corrosion and failure. This results in erratic fuel pressure and leaves you stranded.
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We take a genuine GM module and program it with the latest official software updates specifically for your vehicle’s VIN. This crucial step ensures perfect communication with your vehicle’s Engine Control Module (ECM) and eliminates the need for an expensive trip to the dealership for programming. You get a reliable fix that restores factory performance and fuel efficiency right out of the box.
Case Study: The Intermittent Stall
A customer brought in their 2011 Acadia with a problem that was driving them crazy: it would randomly stall at low speeds but would always restart. No check engine light was on, making it a diagnostic headache. After checking fuel pressure, which was inconsistent, we put the vehicle on the lift. The FSCM, located on the rear crossmember, looked fine externally. However, upon disconnecting it, we found the tell-tale green crust of corrosion inside the connector pins. A new, pre-programmed 2010-2012 Acadia FSCM had them back on the road reliably in under an hour, solving a problem that other shops couldn’t pin down.
Is Your Acadia Showing These Signs of FSCM Failure?
- ✔ Engine cranks but will not start
- ✔ Stalling, especially during acceleration or at idle
- ✔ “Reduced Engine Power” warning light
- ✔ Check Engine Light with codes like P069E, P0230, P025A, or U0109
- ✔ Inconsistent or rough engine performance
- ✔ A buzzing noise from the fuel pump that never stops
A Straightforward Guide to Installation
- ✔ Safety First: Disconnect the negative terminal from your vehicle’s battery.
- ✔ Locate the Module: On the 2010-2012 Acadia, the FSCM is typically mounted to the rear subframe/crossmember, near the fuel tank.
- ✔ Disconnect and Remove: Carefully unplug the electrical connector. Be sure to inspect the harness side for any corrosion. Then, unbolt the old module from its mounting bracket.
- ✔ Install the New Module: Bolt the new, pre-programmed FSCM into place. Securely plug in the electrical connector until it clicks.
- ✔ Final Steps: Reconnect the negative battery terminal. Turn the key to the ‘ON’ position for 10 seconds (without starting) to allow the system to initialize, then start the vehicle to confirm the repair.

Frequently Asked Questions
Why do I need to provide my VIN?
Your VIN is essential for us to program the module with the correct, vehicle-specific software from GM. This ensures it works perfectly with your Acadia’s other computer systems, preventing compatibility issues and error codes.
Is this part difficult to install for a DIYer?
Not at all. For most vehicles like the Acadia, it’s a simple bolt-on, plug-in part. Since we program it beforehand, you don’t need any special scan tools, making it one of the easier electronic component replacements you can do.
What happens if I install it without programming?
An unprogrammed module will not work. The vehicle will likely not start, and you will get communication error codes (like U0109) because the FSCM cannot talk to the main engine computer. Our pre-programming service eliminates this problem entirely.
Will this fix a P069E error code?
Yes, the Diagnostic Trouble Code P069E (Fuel Pump Control Module Requested MIL Illumination) is one of the most common indicators of a failing FSCM. Replacing the module is the standard, effective repair for this code.
Is this a new or used part?
This is a high-quality, tested module that is guaranteed to perform to OEM standards. We load it with brand-new GM software specific to your vehicle, providing a reliable and cost-effective solution.
