Did you get it fixed? (Try pushing it through a right hand corner...)
When you say it won't start do you mean it cranks but won't catch or that you turn the key and nothing happens? Is anything working (dash lights, headlights?) or nothing works?
My guess is something electrical - check battery cables, loose wires from ignition switch, blown fuse. If nothing wrong there (and it cranks but won't start) check for spark. Hook a spare spark plug onto a spark plug wire, ground the threaded part and have someone crank the engine while you watch the spark plug. If there is a good, steady spark then the ignition system is functioning.
If there is spark but it won't start then it must be lacking fuel. (You do have gas in the tank, right?) Check the fuel pump fuse (under the parcel shelf behind the seats).
If there is no spark then check the flywheel sensors. Info is in the L-jet page in my signature.
