you're going to need to have a professional look at your vehicle.

there are so many things that could be wrong. a step by step diagnosis will need to be done to figure what system or component failed you. Fuel system, drive belt, ignition system, battery or charging system... Someone will need to look at your vehicle and get detailed information on what happened and what your car has working and what is not working.
