Known issues on the 1997 K2500 Suburban. Owners of the 1997 Suburban have filed two complaints with NHTSA, one against the engine and one against the fuel system. Those are the areas this manual treats most closely for each of the three power units: engine specifications and torque values, fuel delivery procedures for both the turbocharged diesel and the gasoline V8s, and the diagnostics that follow a hard start, a misfire or a fueling fault. Wiring diagrams support the sensors and circuits involved.
