Is Your 2010 HUMMER H3 Stalling or Refusing to Start?
There’s nothing more frustrating than a vehicle that cranks but won’t run, or worse, stalls unexpectedly in traffic. If your HUMMER H3 is experiencing these issues, a faulty Fuel System Control Module (FSCM) is a very common culprit. This small electronic unit is the brain that tells your fuel pump how much pressure to deliver. When it fails, it can leave you stranded. I’ve seen this exact scenario countless times in my 20+ years as a technician; a perfectly good fuel pump gets blamed when the real issue is this module.
Expert’s Real-World Diagnostic Story: A customer’s 2010 Hummer H3 was brought to my shop on a tow truck. It would crank but never start. They had already spent hundreds replacing the in-tank fuel pump, but the problem remained. A quick check with a scan tool showed no communication with the Fuel System Control Module and a P069E code stored in the ECM. We found the original module, located on the rear frame rail, was heavily corroded from road salt and moisture. After installing one of our pre-programmed modules, the H3 fired right up. This is a classic case where diagnosing the 2010 HUMMER H3 Fuel Module first saves significant time and money.
