I pulled the head to replace headgasket. I left the distributor and wires intact,but when I reassembled the engine I'm not getting a spark to the plugs . My ignition module checked OK. What could it possibly be? The car set for about three weeks with the battery disconnected. If anybody can help me with my problem, please let me know. It is a 1984 Honda Civic
Thank You
