If you have verified that you have no spark from the coil check to see if the distributor signal is present at the tach terminal. (that would be the RPM signal) Power from the ignition switch...?

you could have a bad coil. you could have a bad ignition module. you could have a bad pick up assembly. You would need to check these things when the engine has no spark. See which things are working and which one isn't. Or maybe more than one...
