    Google for instruction video for no spark problems.

    Does your car still have a distributor? If yes check with a spark plug tester if you get
    spark from the coil when starting,also test the spark plug cable to distributor, when
    there is spark check distributor and rotor.also check if rotor turns when starting,
    believe me i have seen it all.
