If the spark at the coil is a brilliant blue spark and can jump around an inch then the coil is good if not then replace the coil, if the spark is good then check for the same spark at the spark plug end, it should also be a bright blue, if not replace the ignition wires along with the cap and rotor. Hope this helps.
