You can turn the key but it will not do anything

Try jumping it from the battery to the low power lead on the starter. It's the solenoid. If it turns over, you've found your problem.

Next, use a test light to see if the solenoid is receiving power when the key is in the 'Start' position. You'll need a helper, obviously. Next, check the clutch pedal position sensor, on the clutch pedal assembly under the dash.
