Is Your Avalanche Stalling, Hesitating, or Refusing to Start?
If you’re dealing with frustrating fuel system issues on your 2010-2012 Chevrolet Avalanche 1500, a faulty Fuel System Control Module (FSCM) is a very common culprit. Located on the frame rail, this critical component is exposed to the elements, and over time, corrosion and electronic failure can lead to a host of problems that leave you stranded. Symptoms often start smallโa slight hesitation or a flicker of the check engine lightโbut can quickly escalate to a no-start condition.
Expert Pro Tip: Check Before You Replace
Before condemning your old FSCM, take a moment to inspect the electrical connector. In my 20+ years in the shop, I’ve seen countless modules replaced when the real issue was a corroded or loose connector. Unplug it and look for any green or white powder-like residue on the pins. Clean them carefully with a small wire brush and electrical contact cleaner. When installing your new module, applying a small amount of dielectric grease to the connector seal is a great preventative measure to keep moisture out and prolong the life of the part.
