Real-World Repair Story
A customer brought in his 2013 Sierra 1500 with a perplexing issue: it would randomly stall at low speeds, sometimes in parking lots, sometimes at traffic lights. There was no consistent Check Engine Light, just an intermittent P069E code stored in history. We checked fuel pressure, which seemed okay at idle in the bay. The owner had already replaced the fuel pump with no success. Knowing these trucks, I went straight for the FPCM on the driver-side frame rail. Sure enough, the back of the module was caked in mud and road salt, and the aluminum casing showed signs of corrosion. This exposure to the elements is the number one killer of these modules. A new, pre-programmed FPCM had him back on the road, stall-free, in under 30 minutes.
