- Unscrew the oil-cap on top of the engine.
- If you look in you can see the cam on top of the head
- Turn the crank-pulley. You might find it easier to hold the belt and move it that way. You need to make sure the crank-pulley moves though.
- While the crank is turning, check to see if the cams move as well.

If they do NOT, then you have a broken timing belt.

Another way would be to inspect the cam and note it's position. Then crank the engine a bit via the starter, and check the cam position again. Do this a couple of times to verify if the cam moves at all.

The above procedure is the only one I can think of that you can do alone. If the belt is okay, you will need to check the spart and the fuel-supply.
