Take a look at the starter relay. sometimes the contacts stay connected. Or will connect on their own without the key turned on.

is this an intermittent problem or is it always on and you have to disconnect the battery to stop the starter from cranking?

if it's always cranking and you have to disconnect the battery, unplug the little dark blue and orange wire from the starter and touch the battery cable back up to the battery for just a second. If still want to crank the starter get a new relay.

if it's an intermittent think you will have to wait until it acts up and check it the same way. If disconnecting the small dark blue and orange wire from the relay doesn't stop the starter from running replace the relay.

If unplugging the small dark blue and orange wire does turn off the relay and the starter does stop, you need to look at the wiring from the ignition switch to see where the power is coming from to turn the relay on.

that's if you have the relay that bolts to the body in the hood area. If you have the relay that is the square plastic type you can just pull that relay from it's holder and see if the engine turns off. If it turns off try another relay or get the relay tested.
