Replace ignition switch. I should say pull it and see if the shaft moves.

the gearing or the switch has gone bad so all you can do is disconnect the battery and unplug the alternator as well to shut off the engine. you can disable the fuel pump fuse although the battery will drain since power is still going through the circuits

my pontiac did the same thing and all i had to do was replace the 40amp fuse. you can have someone turning the key while you hit the starter from underneath, if it starts then you need a new starter, if it dont then no, its something else. mine did the exact same thing and it was the 40amp fuse under the hod.

The sound you call purring is the starter motor spinning. Your starter is basically a two function device. It spins to turn the flywheel and therefore the engine over so it can start. The other thing it must to (which yours isn't) is a motion like a solenoid, the bendix, that drives the starters output shaft with a small gear that has to engage the flywheel teeth. That outward motion inserts the starter pinion into contact with the flywheel. When the starter is disengaged, the bendix is also disengaged, withdrawing the starter pinion from the flywheel teeth and back into it's resting position. It sound like your starter's bendix is stuck and isn't being moved outward and so isn't engaging the flywheel. In the old days we used to strike the starter motor with a hammer to free a stuck bendix. This is risky these days because the design of the start motors (many of them) are made inside out. That is, instead of field coil windings being close to the outside of the case, they are deep inside and spin with the starter. Magnets are now just inside the case and they can break like ceramic if the starter motor is struck. Replacement of the starter is in order for a long-term fix.
