I've been having issues with my car not starting after driving for awhile. Like its too hot or something. Last night i turned my car off, but the key wont go to the off position. After messing with it for 15 minutes, i unplugged the battery. This morning i stuck the negative cable back on the battery and tried to start my car. It turns over but wont start. Key is still stuck. Its got half a tank of gas, and i jumped the battery in case it was low.
