Regarding electronic ignition modules, is it possible that the timing could be so far out of range that no spark to a grounded spark plug would be seen?

 

I think not.

Which electronic ignition module are you using, Ultima, Crane, etc? Post a pic of the installation. Give more information please.

 

No, if that were the case, you'd still get spark but not when you needed it to ignite.
The pick-up, the wire, kill switch or the coil is bad.

 

I got it guys. Spent the afternoon in the shop and replaced the suspect Dyna S dual fire ignition module. I keep everything else the same. I've got a beautiful spark now. Appreciate the responses.
