Have you been working on the ignition switch previously? Sometimes what can happen is that the ignition switches can separate the metal from the plastic. The plastic piece is just pressed into the metal housing and can work loose over time. When this happens it can turn inside the metal housing and throw the sequence off, for example in position 2 it is cranking still instead of starting. I've had this happen on a car I was working on where the previous owner worke don the switch.
