    Abstract: A control system includes a starter control module, a mode setting module, a fuel pressure control module, and a fuel control module. The starter control module initiates cranking of a spark ignition direct injection (SIDI) engine in response to user actuation of an ignition switch. The mode setting module sets a mode of operation to a cold start mode when an engine coolant temperature is less than a predetermined temperature during the cranking. The fuel pressure control module, in response to the setting of the mode to the cold start mode, determines a target fuel rail pressure. The fuel control module controls fueling during the cranking based on the target fuel rail pressure.

    Abstract: A cold start control system for a vehicle having a spark ignition direct injection (SIDI) engine includes a startup control module and a fuel actuator module. The startup control module sets a mode of operation to a cold start mode. In response to setting the mode to the cold start mode, the startup control module determines target combustion parameters and a predetermined amount of fuel, wherein the predetermined amount of fuel is less than an amount of fuel required to initiate a combustion stroke of the SIDI engine. The startup control module controls injection of the predetermined amount of fuel, during cranking of the SIDI engine, based on the target combustion parameters. The fuel actuator module injects the predetermined amount of fuel, during cranking, based on the target combustion parameters.

    Abstract: A startup/shutdown control module selectively generates an engine startup command when an engine of the vehicle is off. A starter control module applies power to a starter motor when the engine startup command is generated. A valve control module, in response to the generation of the engine startup command: operates intake valves of cylinders of the engine in a low lift mode when an engine temperature is less than a predetermined temperature; and operates the intake valves of the cylinders of the engine in a high lift mode when the engine temperature is greater than the predetermined temperature.

    Abstract: A system according to the principles of the present disclosure includes an engine cranking module and a throttle control module. The engine cranking module determines whether an engine is cranking based on at least one of an input received from an ignition system and engine speed, and generates a signal indicating whether the engine is cranking. The throttle control module selectively adjusts a throttle of the engine to a fully closed position when the signal indicates that the engine is cranking.
