Hey Lewis,
Have you checked the fuses in the driver’s side fuse box that sits right above the kick panel? There’s a 15A Engine fuse and 75A Ignition fuse. There’s a Main Relay just inside the kick panel.
I don't know for sure if those failures would cause no spark, but without testing myself, probably will. The last time I had a no spark, it was the ignitor on my 1985 22R, and it was, so far, the only ignition failure I've had.
Gnarls.
