Abstract: A method of starting an engine having a fuel rail, one or more fuel injectors, and one or more spark plugs. In one embodiment, the method includes initializing a starting operation of the engine and suppressing the engine from starting by retarding a spark timing of the one or more spark plugs from normal spark timing. The method also includes purging, while the spark timing is being retarded, the fuel rail of the engine by operating the one or more fuel injectors. Additionally, the method includes advancing the spark timing after a first duration has passed or the engine has started.
