My car died on way home from work and will not turn over. on 2002 Saturn SL1

Camshaft sensor was replaced Tuesday. Came home from work and turned off car for about 10 minutes. Got back in car to pick up son from school and car would not start again.

Do you mean the starter is not turning the motor, or engine is turning but will not fire up(start)? The CRANKshaft sensors give some problems on this car! That is if it cranks but will not start!
