Now when I checked it again still have coil spark but no spark to the plug.
Please elaborate a little on the above statement. Are you saying there is a high voltage spark from the center coil wire, but it's not getting to the spark plugs, or is there no spark at all from the coil wire? The only thing between the center coil tower and the spark plug is the distributor rotor, and it can develop a short to the distributor shaft. Try changing rotors, or at least look yours over with a strong light up inside the hole where it slides onto the shaft. If you see a tiny charred hole, you just found the problem.
