Restore Fuel Delivery and Engine Performance
Is your 2010 Saturn Vue or other GM vehicle experiencing frustrating issues like engine stalling, extended cranking times, or a complete no-start condition? 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 these modules fail frequently, causing intermittent problems that can be a nightmare to diagnose. This module is the brain behind your fuel pump, regulating its speed and pressure. When it fails, your engine is starved of the fuel it needs to run reliably.
This isn’t just a replacement part; it’s a complete solution. We take the guesswork and extra cost out of the repair by pre-programming this 2010 Vue Fuel System Control Module to your vehicle’s specific VIN. This means it arrives at your door ready for installation, with the latest GM software updates already loaded. You can bypass the expensive trip to the dealership for programming, saving you time and hundreds of dollars. Just provide your VIN at checkout, and we’ll handle the rest, ensuring a seamless, plug-and-play repair.
Case Study: A Tricky Diagnosis
A customer brought in a 2011 Chevy Tahoe that would randomly stall at stoplights. They had already replaced the fuel pump, but the problem persisted. No check engine light was on, but a scan with a professional tool revealed a stored history code, U0109 – Lost Communication With Fuel Pump Control Module. Instead of throwing more parts at it, we inspected the FSCM on the frame rail. It showed signs of corrosion from road salt and moisture. After installing a VIN-programmed module like this one, the stalling issue was completely resolved. It’s a classic example of how diagnosing the control side of the system saves money and frustration.
Common Signs of a Failing FSCM
If you’re noticing any of the following issues, a failing fuel system control module is a likely cause. A faulty module can often mimic a bad fuel pump, so it’s a critical component to check.
- ✔ Engine cranks but will not start
- ✔ Vehicle stalls unexpectedly, especially under load or when warm
- ✔ Hesitation or stumbling during acceleration
- ✔ Reduced engine power and poor fuel economy
- ✔ Check Engine Light with codes like P069E, P0230, P025A, or U0109
A Straightforward Guide to Installation
For the handy DIYer or professional mechanic, replacing the FSCM is a manageable job. The location varies by vehicle, from the frame rail on trucks to the rear compartment on SUVs and sedans. For the 2010 Saturn Vue, it’s typically found in the right-hand rear of the engine compartment.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the Module: Find the old FSCM. On many GM trucks and SUVs, it’s mounted on the driver-side frame rail. On other models like the Vue, check the specified location. It’s a small black box with electrical connectors.
- Disconnect and Remove: Carefully unplug the electrical connectors. Be gentle to avoid breaking the locking tabs. Then, unbolt the module from its mounting location.
- Install the New Module: Bolt the new, pre-programmed FSCM into place. Ensure it is securely mounted.
- 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
Do I really need to provide my VIN?
Do I really need to provide my VIN?
Yes, providing your 17-digit VIN is essential. We use it to load the exact software and calibrations your vehicle requires from the factory. This step is what makes the module a true plug-and-play part and ensures it communicates correctly with your vehicle’s other computers.
Is this part difficult to install myself?
For most individuals with basic mechanical skills and tools, this is a straightforward replacement. The most challenging part is often accessing the module, which is typically mounted on the vehicle’s frame or in a rear compartment. Our installation guide above provides the general steps.
How do I know if my FSCM is bad and not the fuel pump?
The symptoms are very similar. A good diagnostic step is to check for power at the fuel pump connector while a helper cranks the engine. If there’s no power or intermittent power, the FSCM is the likely culprit. Diagnostic trouble codes like U0109 or P069E also point directly to the module or its circuit.
Will this fix my P069E error code?
Yes, the code P069E (Fuel Pump Control Module Requested MIL Illumination) is a very common indicator of an internal FSCM failure. Replacing the module with this pre-programmed unit is the correct repair for this code, assuming the wiring is intact.
What happens if I install it without programming?
An unprogrammed module will not work. It will not have the correct software to communicate with your vehicle’s ECM/PCM, and the fuel pump will not activate. Our pre-programming service eliminates this problem entirely.
