Abstract
Disclosed are a method and a system for diagnosing failure of a gasoline direct injection (GDI) engine that can diagnose a device (or part) causing failure through forcible driving control of a related device (or part) when failure occurs in the GDI engine. The method for diagnosing failure of a GDI engine may include verifying whether a failure code is output from an engine control unit that controls the engine, and diagnosing whether a fuel system device is in a failure state by forcibly driving the fuel system device of the engine with a set control value when the failure code is output from the engine control unit.
