What would stop car from turning over?

there are many things that will stop it from turning over, the obvious would be fuel (lack of) vacuum lines that are cracked, bad starter, dead battery and alternator injectors might be disconnected. if you have any more details on it please email me and i might be able to send more info aceaspade2000@Yahoo.com . use car problems as the subject

Lack of fuel does not stop an engine from turning over. It prevents an engine from starting.

The engine probably will not turn over because of some electrical problem,,,battery,bad connections,bad starter,bad ignition switch,etc.
