1. Check its definately not in gear (go through the whole gearbox if necessary)
This sounds most likely the prob, as has been said above.
2. Check all block connectors to ensure they are dry & have no corrosion.
3. Have you tried bump starting it?
4. Have you tried putting a power straight to the starter motor?
To do this: Pull the boot off the wire that goes to the starter motor & with a set of jump leads or a jump pack clip the earth lead anywhere onto the engine & flash the positive lead to the starter motor to see if it fires (tho you MUST check its in neutral first & that the ignition is on) If this works, then there isnt a problem in the ignition circuit - you'll have to look elsewhere.
To be safe, get someone to hold the clutch in while you flash the starter
