no spark 1978 charger 115

[bigdev1968]

I have just gotten a 1978 chrysler charger deluxe 115 model1159h8b, I am not getting any spark at any of the 4 spark plugs. A friend at work said something about a cdi box? im not sure what that is. I am assuming it the box that the coil is mounted to and i have tried to measure some voltage on to of the coil but not reading any there. Also i changed the starter soilinoid, the old one had rubber isolaters on the bolts-the new one doesn't. Would that make any difference? When i turn the key the the starter turns and the choke button is working so im assuming im wired correctly. Any help would be greatly appreciated.
