First get engine to top dead center with compression gauge or compression whistle , next rotate harmonic balancer so the slot is matched between the little numbs on the timing cover. Next remove rotor button on the distributor now the number eight will be on top of a square hole under rotor button .You need to move that over to the little pointer on the inside of the outer part of the distributor it has a pointer with a number 6 on it (it should be on the passenger side ). Lift up distributor and move the number 8 on the center part till you are over or just before the little pointer on the outer edge of the plastic distributor. If not all the way down in, the oil pump is not clocked in properly hold down on the distributor and have some one click the starter make sure you unplug the coil though and just a couple clicks holding dowm on the rotor top of distributor that should bring it in place. Put back together and try to start the vehicle and then if it stats do the timing set up for syc through the scanner at 1500 rpm move distributor till you see +- 2degrees . Thn tighten your distributor and test drive .
