be specific, can you still turn on your headlights or any interior lights, radio still on?
if so you could run in the same problem i was running into, before. which was the white switch behind the clutch. which for some odd reason when you press the clutch in it's not making a good contact to to white switch.. i believe it's called the clutch start switch..
just reach down under your clutch pedal feel for the button, make sure your car is in neutral & with the other hand turn on your ignition..
