I drive a 1998 BMW 328i. This evening, I turned the key in the ignition to start the car. The engine turned over half-way and then stopped. It made an odd sound as if the starter seized up. At that time, the ignition seized up in the "on" position. The constant power is on, the automatic transmission can be shifted, and the key can be removed from the ignition. I tried removing the negative battery cable and reattaching it to no effect. At this time the car is sitting with the battery disconnected. What can I do and get the car back up and running?
