define wont turn over. If its doesn;t turn, it wont start. That means the solenoid is not engaging.

Do you maybe mean "won't start"?

well you have no fuel. no spark or no compression

no spark is easiest to check ..put a spare plug on a lead,ground it and turn it over and see if you have spark
..no compresion ..timing belt.. inspect under the covers
..no fuel .. a bit tougher as you may need a fuel presssure tester or take an injector out ...

but i have to ask .. you have gas right ?

so this can certainly be the ignition switch. It happened to me (C4).

But as airbag said, fire + gas + air = bang. Do you have all 3?

Having a 3/4 full gas tank is of no consequence. Is it squirting out the injectors?

Is the spark plug sparking?
