ABSTRACT:
A backup apparatus for ignition and fuel system provided with an ignition system backup circuit and a fuel system backup circuit to be used in case of a breakdown of a main circuit. The fuel system backup circuit outputs a drive signal to a fuel injection valve by using either an ignition signal for an ignition device from the ignition system backup circuit, or an ignition diagnosis signal from the ignition device as a trigger timing. When the ignition system backup circuit breaks down, neither the ignition signal from the ignition system backup circuit nor the ignition diagnosis signal from the ignition, device is generated, so that the supply of fuel to the engine is stopped.
