How did you verify the spark?
You may want to replace the distributer cap and rotor, there may not be a spark to all cylinders.
Make sure the notch on your cap is lined up correctly with the distributer. You can have the cap 180 off and be sending the spark to the wrong cylinders.
Did you rotate the distributer when you replaced your ignition wires? There is a bolt that holds a piece of metal that holds the distributer in place. You loosen the bolt and rotate the distributer to adjust the timing. You may have accidentally messed up the timing.
