Went to the store, parked, on start engine grinded and seized.

I am 99% sure i need a new engine.

After parking at a local hardware store, I turned the car off, and after 4 minutes when I went back in to start, the engine made a horrible chainsaw noise but turned over, then finally seized.

I called the lady for a ride home. Don't sugar coat it, what could it be?

The timing could not be worse!
