No spark from coil

[visionary]

I recently purchase a '73 240z in Denver, Colorado. The car had been stored for the last five or so years with apporimatly two months of driving time over that period.

On my return trip to Boise, Idaho, the transmission (automatic) began slippping out of gear. I had the transmission rebuilt, replaced the flexplate, torque converter, and installed a new starter as the old starter was damaging the teeth on the flexplate.

While driving the car to break in the reubuilt transmission, I ran out of gas. After putting fuel in the tank, the car would run for a few miles and then stall. I replaced the electronic fuel pump, both inline filters, and blew out the main fuel line. Prior to bringing the car back from Colorado, I had replaced the SU's with refurbished throttle bodies from Z-therapy as well as a complete rebuild on the carbs, which seemed to work well. The car is delivering fuel to the engine well now, however, I have no spark from the coil.

I have replaced the old coil with a high output Accel, replaced the points and condenser with out success.

If anyone has any ideas I would appreciate a note. At his point I am a little stumped...

Thanks

An update:

After checking the wiring diagrams, and using my trusty Ohmmeter, I became supect of the resister module. The meter gave a 1.5 ohm reading, however, I suspected that the module was failing at load. I replaced the module and the spark returned. Hope this helps others in this situation...
