Is Your 2010 Hummer H3 Stalling or Refusing to Start?
There’s nothing more frustrating than turning the key on your H3 and getting nothing but a crank, or having it stall out unexpectedly. If you’re experiencing erratic fuel delivery, a check engine light with code P069E, or a complete no-start condition, the problem often isn’t the fuel pump itselfโit’s the small computer that controls it: the Fuel System Control Module (FSCM).
From the Shop Floor: “A customer’s 2010 Hummer H3 came in last week with these exact symptoms. It would crank but not start, and they had already replaced the in-tank fuel pump, assuming that was the issue. After a quick diagnostic check, we found the real culprit. The original FSCM, mounted on the rear frame rail, was heavily corroded from years of exposure to road salt and moisture. This is a failure I’ve seen hundreds of times on these GM platforms. We swapped in a new module, and the H3 fired right up.”

Easy Installation Guide for Your 2010 HUMMER H3 FSCM
You can get your Hummer running properly again in your own driveway. The FSCM on the 2010 H3 is located on the rear frame. Follow these simple steps for a successful installation:
- Safety First: Disconnect the negative terminal from your vehicle’s battery.
- Locate the Module: Find the old FSCM mounted to the rear frame of your H3. It’s a small, black box with an electrical connector.
- Disconnect and Remove: Carefully unplug the electrical harness. Then, unbolt the module from the frame. These bolts can sometimes be rusty, so a little penetrating oil might help.
- Install the New Module: Bolt the new, pre-programmed FSCM into the same location.
- Connect and Secure: Plug the electrical connector firmly into the new module until it clicks. Reconnect your battery terminal.
- Final Step: Turn the key to the ‘On’ position (without starting) for 10-15 seconds to allow the system to prime, then start your engine. Your fuel delivery issues should be resolved.
Expert Pro Tip: Before plugging in your new FSCM, take a moment to inspect the vehicle’s harness connector. Use a small brush and electrical contact cleaner to remove any green or white corrosion from the pins. A clean connection is critical for the longevity and proper function of the new module.
