From the Technician’s Bench
As a mechanic, I’ve seen dozens of these GM trucks and SUVs come in on a tow truck with a no-start condition. Nine times out of ten, the culprit is this Fuel System Control Module. On most of these vehicles, it’s mounted on the frame rail, exposed to road salt, water, and debris. Over time, corrosion attacks the housing and the internal circuit board, leading to intermittent or complete failure. Replacing it isn’t just a repair; it’s a crucial step in ensuring your vehicle’s long-term dependability. Getting a pre-programmed module like this one saves you a massive headache and hundreds of dollars compared to the dealership route.
