Restore Your Vehicle’s Performance and Reliability
Is your GM vehicle experiencing frustrating issues like stalling, hesitation, or a complete failure to start? Before you suspect the fuel pump itself, the problem often lies with a faulty Fuel System Control Module (FSCM). This critical component, also known as a fuel pump driver module, regulates the voltage sent to your fuel pump, ensuring precise fuel delivery for optimal engine performance. When it fails, it can leave you stranded. This is the definitive solution for a wide range of GM cars, trucks, and SUVs, including a direct-fit for your 2010 VUE Fuel System Control Module.
We take the guesswork and extra cost out of the repair. Unlike buying a blank module that requires a trip to the dealership for expensive programming, this FSCM arrives at your door ready for installation. Simply provide us with your vehicle’s VIN during checkout, and our technicians will flash the module with the latest, most stable GM software specific to your vehicle. This ensures seamless communication with your vehicle’s computer and restores factory performance right out of the box.
From the Diagnostic Bay: The Case of the Intermittent Stall
I remember a 2011 Silverado that came into my shop with a complaint that stumped a few other mechanics. The owner reported random “Reduced Engine Power” warnings and occasional stalling, but it never acted up in the service bay. We could find no active codes. After checking fuel pressure, which was perfect at idle, I took it for a long test drive with a scan tool hooked up. Sure enough, after hitting a bumpy section of road, the fuel pressure reading dropped to zero for a split second, and the truck stumbled. Back on the lift, a close inspection of the FSCM mounted on the frame rail revealed the issue: the casing had a hairline crack, and road salt and moisture had corroded the internal circuit board. This is a textbook failure I’ve seen dozens of times. A new, properly sealed module like this one is the only permanent fix.
Is Your Vehicle Showing These Symptoms?
- ✔ Engine cranks but will not start
- ✔ Stalling, especially under load or when warm
- ✔ Severe engine hesitation or sputtering during acceleration
- ✔ “Reduced Engine Power” message on the dashboard
- ✔ Check Engine Light with codes like P069E, P025A, P0230, or U0109
- ✔ Inconsistent fuel pressure readings
A Straightforward Guide to Installation
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before beginning any electrical work.
- ✔ Locate the Module: On most GM trucks and SUVs (like the Tahoe or Sierra), the FSCM is mounted on the driver’s side frame rail, near the spare tire. On cars (like the CTS or Impala) or crossovers (like your 2010 Saturn Vue), it may be in the trunk area, under a trim panel, or on a rear crossmember. A quick search for your specific model will confirm its location.
- ✔ Disconnect and Remove: Carefully unplug the electrical connectors. Press the release tabs firmly to avoid breaking them. Then, remove the bolts or nuts holding the old module in place.
- ✔ Install the New Module: Mount your new, pre-programmed FSCM in the same location and secure it with the original hardware.
- ✔ Reconnect and Test: Plug the electrical connectors back in until they click securely. Reconnect the negative battery terminal. Turn the key to the ‘On’ position for a few seconds to prime the system, then start the engine to verify the repair.

Frequently Asked Questions
Frequently Asked Questions
Do I really need to provide my VIN?
Yes, absolutely. Providing your VIN is essential. We use it to load the correct, vehicle-specific software from GM onto your module before shipping. This step is what makes the installation a simple plug-and-play process without needing a dealer visit.
Is this part difficult to install myself?
For most DIYers with basic tools, this is a very manageable job. The module is typically held on by just a few bolts and has simple plug-in electrical connectors. The most challenging part is often just accessing it, but our installation guide above provides common locations.
What is the difference between this and a cheaper, non-programmed module?
A non-programmed module is essentially a blank box. After installing it, your vehicle will not start until you have it towed to a dealership or a shop with advanced scan tools to have it programmed, which can add $150-$250+ to your total repair cost. Our module eliminates that entire step and expense.
How do I know if my FSCM is bad and not my fuel pump?
While symptoms can be similar, a common test is to check for voltage at the fuel pump connector while a helper cranks the engine. If there’s no voltage, the FSCM is a prime suspect. Diagnostic codes like U0109 (Lost Communication with FSCM) are also a clear indicator that the module itself is the problem.
Will this fix my ‘Reduced Engine Power’ light?
If the ‘Reduced Engine Power’ mode is being triggered by faulty signals or a lack of communication from the fuel system control module (a very common cause), then yes, replacing it with this correctly programmed unit will resolve the issue.
