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.
