Should be a round punchmark on the face of the crankshaft gear. It lines up with a single tooth. Wipe the gear clean, use a little carb cleaner. (NO flames, or sparks nearby, well ventilated area)

Count the teeth in the timing belt. There should be 133 teeth on the belt.
There is 43 teeth in-between the timing mark of the camshaft, and the timing mark on the crankshaft.
