Start with the basics. did you pull the distributor to work on it? If so is it seated properly and is it rotating? If so, next step check all connections to everything then start tracing electricity to make sure it is getting where it needs to go. if you got juice in all the right places then you have a bad component and you need to figure out which one it is, box, coil pickup etc. Mine turned out to be a sheered pin on the distributor. :yuk:
