Help!!! won't start....Mechanic please!

Surely you didn't open the timing cover to change a rear main seal but probably did pull the distributer. So you rotate the balancer to timing mark at zero and drop the distruter in. It dont start. Now forget going back to the balancer mark. Just pull the distributer cap and note where the rotor is pointing, lift the distributer and turn it 1/2 a round and try to start it again.
