The rotor is bolted directly to the end of the cam shaft and there is only one thing that makes that turn. The timing belt. It's not a hard fix, but you'd better do it right. You have an interference motor which means if the cam and crank aren't in sync with each other you destroy the valves and pistons etc. Maybe why you got the car so cheap (hope not though). Get a book (chiltons etc.) follow the directions cross your fingers and hope for the best, I'm pullin for ya. One other thing if the engine light stays lit while your cranking it mean the ECU is not picking up a crank signal from the magnetic pickup on the front of the engine. That will also prevent it from starting and running.
