You have to make sure the number one cylinder is in the top dead center (TDC) position. Then on the cam shaft pulley there is a small hole in one of the spokes. This hole lines up with a stamp mark on the end of the engine. The crank shaft pulley has a v-notch in the outer edge. With the number one cylinder at TDC, this v-notch lines up to the TDC mark on the lower timing cover.
