What is wrong with this car?? on 1996 Buick Century

I was waiting for my food at burger king with the engine still running and all of the sudden it just stopped. when i went to crank it up a started again but made a crackling noise. I turned it off waited and went to start again but wouldnt start. when i turn the key in the ignition it does not make a sound..quiet..lights are on and everything but i do not know what this could be for sure becasue prior to this it had been running good with the exception of me having to get a new radiator last week

Sound like something broken in or around the engine.
You have to show it to a mechanic it could be anything.
