No Spark Won't Start

dougmMember

I modified my ignition system a few weeks ago to install a relay to supply power to the Duraspark II ignition as per George P diagram.
After I completed the install, car fired right up, ran great. I started it about 15 times, engine cold and hot. Worked flawlessly. That was about 3 weks ago. Yesterday I went to start the car and NOTHING!

Battery fully charged
Tested the new relay for ignition power OK
Direct power pasing through relay when swithed OK
Changed to a spare coil NO change
Changed to my backup Duraspark module NO change
Checked my wiring connections, everything seems good and tight.

If this happened right after the install I would assume I did something wrong BUT the car started (about 15 times) and ran flawlessly right after I was finished. That was about three weeks ago.
Next time I try to start the car NOTHING

This one has me baffled

Any ideas would be greatly appreciated!

Thanks,
Doug M
