Chevrolet S10 truck starts and runs briefly before stalling despite functional fuel pump on Chevrolet S10

Some Chevrolet S10 owners report experiencing issues where the truck starts and runs briefly before stalling, even with a functional fuel pump. These problems may stem from bad gas or water in the gas tank, which can lead to abrupt stalling and rough engine performance. Additionally, fuel system issues, such as faulty fuel filters, pump problems, or injector malfunctions, are common culprits that can cause sputtering and stalling. Ignition problems, including faulty spark plugs or ignition coils, can also result in difficulty starting and engine sputtering. Other potential causes include high spots in the fuel tank and issues with ground wires near the brake lights. To address these concerns, owners are advised to check fuel quality, inspect the fuel system, examine ignition components, and review other related factors that could contribute to the stalling issue.
