An engine control apparatus and related control method for an engine are disclosed wherein cylinder discrimination is executed based on a crank signal and a cam signal under a normal signal mode. If a failure occurs in either the crank signal or the cam signal, the cylinder discrimination is executed based on a normal one of the crank signal and the cam signal. A starter device is driven to crank up the engine until judgment is made that the engine enters a running state. A duration time for the starter device to be driven is measured and if the duration time reaches a limit time, the driving state of the starter device is interrupted. When either the crank signal or the cam signal encounters the failure, the limit time is set to a longer time than a preset time for the normal signal mode.
