摘要: A method for starting an engine includes sensing a triggering event and monitoring pressure in a fuel rail. A cam shaft of the engine is oscillated with a cam phaser. The cam shaft does not complete a full rotation during the oscillation. A fuel rail pump is operated with the oscillating cam shaft until the monitored pressure in the fuel rail reaches a minimum level, and the engine is started after reaching the minimum level.
