Problem overview

Some GMC Sonoma owners report experiencing engine shutdowns while driving, which may be attributed to various issues. These include fuel system problems, such as malfunctioning fuel pumps or injectors, that can lead to the engine stalling. Additionally, some owners have encountered ignition system failures, like faulty ignition switches, which can prevent the engine from restarting. Contaminated or old gasoline has also been reported as a cause for unexpected engine shutdowns. Furthermore, failures in electrical components, such as the ignition coil or distributor cap, can contribute to these issues. To address these concerns, it is recommended that owners have their fuel and ignition systems inspected, assess the quality of fuel used, and check the condition of related electrical components. If the problem continues, seeking assistance from a qualified mechanic is advised to ensure safe vehicle operation.
