From what i've seen and read the fuel injectors will shut off as soon as the car starts, like within 1 second of the car starting if its the passlock.
The IAC controls the amount of air passing the throttle plate when its closed at idle. You can pull it out and clean it if it has carbon on it. It should be shiny not black.
When I had my key turned forward to reset, it took 30 mins for the car to start.
