Car starts itself (no key in ignition)

I have an '03 Taurus

I turned my key in ignition, no crank no start. As I turned key to off position and pull it out the engine slowly cranked itself with no key in ignition. After that tried to jump car, when jumper cables were connected engine again cranked (no key in ignition) but didn't start. Disconnected battery and charged it. When reconnecting battery car again tried starting without key in ignition.
All 3 times the ignition was in the off position, the car never had a key in the ignition, and the car turned over slowly without firing.

Additional note: I've had to replace the starter three times in three years.

Does anyone know what would cause the ignition to be bypassed and power to be supplied to the starter?

Aftermarket remote start?

I bought it used, and wasn't told of a remote start. Not sure how to check for an old remote start.

Take a look for any extraneous wiring coming off the ignition switch or spliced into the leads coming off of it

My old 1993 Taurus ignition switch would start the car by turning the key slot black paddle without the key in place. Something in the tumbler was broken. Are you saying the car starts without turning anything at all???? By its self!!

Correct the car attempts to start itself with no turning.

I removed the bottom shroud from the steering column and didn't see any extraneous wiring around the ignition switch.

I have installed five remote starts in my Taurus. You should see two boxes, one about two by three inches and another about three by four inches with about fifteen to twenty wires running to it. Most remote starts have to have a antenna wire that is wrapped around the ignition key tumbler. You can see that by removing the shroud on the steering column. You need to remove the tumbler to get the upper shroud off. But there could also be an antenna mounted to the windshield by the rear view mirror.

Inspect and/or replace the ignition switch (switch, not the lock cylinder).

Yep, if no remote start present that's the ticket

My just bought '03 has a Viper remote on the key ring. Looked under and there is a key clue. Aftermarket wire "tee'd" on one wire near the brake light switch on the brake pedal.
I do not know how to use or program the Viper yet. Not a priority now.
