1995 Ford Ranger Timing belt replacement

My timing belt broke while the vehicle was idling. I attempted to replace it by lining up the timing marks according to a Hasting manual for belt replacement. After the first attempt when the engine would not fire I discovered what appear to be two timing marks on the cam. They both look like the mark that is on the oil pump gear. One sticks up higher than the other. How do I go about making sure that I have the right marks aligned and the the Crank is not 180 off? Frustratred!
