ABSTRACT:
A fuel controller for an internal combustion engine has a crank angle sensor which generates a cylinder recognition signal corresponding to a prescribed cylinder of the engine. If a microcomputer 12 determines that the cylinder recognition signal has not changed during the occurrence of a prescribed number of changes in the level of a crank angle signal, the cylinder recognition signal is determined to be abnormal and fuel injectors of the engine are not actuated if the engine has been running for at least a prescribed length of time, thereby cutting off the supply of fuel to the engine.
