I've got an HEI external coil DIstributor, and its not outputting any spark.. I'm pretty sure this means the coil, ecm or pickup is shot, is there any way to test which one is broke before I tear anything out? Thanks.

 

Since the Module was so easy to get out and I figured from the posts I read that it was most likely the failed part, so I took it in and had it checked, and sure enough it was failed. As a side note, at schucks, if the internet has a lower price and you show them that, they'll match it, saved me 40 bucks. Thanks for the help!
