Abstract
A system for a vehicle includes an initialization module and a purge control module. The initialization module generates an initialization signal based on a crankshaft speed signal and/or a fuel rail pressure signal. The initialization module also generates the initialization signal based on an initial purge value and an assembly-line monitoring value. The purge control module generates a purge signal to purge air from a fuel injection system of an engine. The purge signal is generated when the crankshaft speed signal indicates that a crankshaft of the engine is stationary and/or the fuel rail pressure signal indicates that a fuel rail pressure is less than a predetermined value. The purge signal is also generated based on the initialization signal.
