There is a "notch" on the oil pump body that lines up with the end notch behind the crankshaft pulley.
The oil pump does not have timing marks. With the belt OFF, set the crank to TDC, and align it's marks. Next set the cam to it's marks, THEN set the belt in, without moving any pulleys (a little tricky but you can do it).
