um, well, if the engine isnt turning over, then your battery is either too flat to start (its trying to start the engine but theres not enough current to make it move at all), or the ignition relay is not switching on turning the starter motor on when you turn the key.

a very long list of things. could be almost anything from an empty fuel tank to a flat battery.

When you turn the ignition, is there no sound at all? A buzz? A bunch of fast clicks? They all mean different diagnoses.

please be more specific, would that light symbol be a battery sign,
