Is Your Hummer H3 Stalling, Sputtering, or Refusing to Start?

Expert Insight from a 20-Year Technician
I’ve seen countless GM trucks and SUVs, including the H3, come into the shop with these exact fuel system gremlins. The original FSCMs were often mounted on the frame rail, exposed to water, salt, and vibrations, which leads to internal corrosion and failure. Simply replacing it with another old module is a temporary fix. Our solution provides a module loaded with the latest GM software updates, which often include improved logic to handle voltage fluctuations and protect the circuitry. By providing your VIN, you’re not just getting a part; you’re getting a permanent, updated solution that a dealer would charge a premium for. This is the smart, reliable repair.
Frequently Asked Questions
How do I provide my VIN for programming?
After you complete your purchase, simply send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot ship your order until we receive this information, as the programming is essential for the module to function in your 2010 Hummer H3.
Is this a difficult part to install?
For someone with basic mechanical skills, this is a straightforward job. The FSCM is typically located on the driver’s side frame rail. It involves disconnecting the battery, unplugging the electrical connectors, and removing a few bolts. Since our module is pre-programmed, no special tools are needed for software setup, making it a true plug-and-play repair.
Will this fix my P069E trouble code?
Yes, the P069E code (Fuel Pump Control Module Commanded On) is one of the most common indicators of a failed FSCM. Replacing the faulty original module with our correctly programmed unit is the specific and reliable fix for this code and related performance issues.
What happens if I install it without programming?
An unprogrammed Fuel System Control Module will not work. The vehicle’s computer systems will not recognize it, and the fuel pump will not operate. Your vehicle will not start. Our pre-programming service is critical to ensure the part works correctly right out of the box.
Is this part compatible with other vehicles?
Yes, while this listing is for a 2010 Hummer H3 Fuel System Control Module, this part also fits a wide range of other GM trucks and SUVs from that era, such as the Silverado, Sierra, Tahoe, and Escalade. Please check the detailed fitment list in our description to confirm compatibility with your specific vehicle.
