On the 2011 Buick GL8, the fuel pump control module is a component I frequently encounter during repairs. Its location is relatively fixed, usually hidden under the floor near or beneath the second-row seats—sometimes you need to lift the seat cushion to spot a small box-like unit. I recall it's positioned in the rear section of the vehicle, close to the fuel tank, a design choice aimed at minimizing electrical interference and easing maintenance. If you ever attempt to locate it yourself, remember to disconnect the battery first to prevent electric shock—safety first! Common issues include loose or moisture-damaged connectors, which can cause the fuel pump to fail and prevent the car from starting. When working on it, it's wise to have a wrench and gloves handy, though I don’t recommend non-professionals tinkering with it—messing up the wiring could lead to bigger headaches. Checking that the module is securely fastened before driving can help avoid embarrassing roadside stall situations.
