Abstract
A control system includes an engine enable module and a fuel control module. The engine enable module determines whether predetermined operating conditions of a spark ignition direct injection (SIDI) engine are satisfied and enables an engine prime mode when the predetermined operating conditions are satisfied. The fuel control module controls a fuel injector to deliver a prime pulse to a cylinder of the SIDI engine when the engine prime mode is enabled. The fuel injector delivers the prime pulse by opening for a pulse width to inject fuel directly into the cylinder when the SIDI engine is stopped.
