Ignition relay problem? No spark and EDU out on 88 9kT

This started as an intermittent problem, usually going aroung a corner the gauges would die, and the edu would go out and the engine would die. Usually it would come right back to life.
Now It will crank and crank and get no sparking. I've tried feeding battery voltage back into the edu's positive terminal, and that worked for awhile, but not anymore.
Once, while feeding power back into the edu, (with the engine off and not cranking) the ignition sparked, and made the engine turn over by itself! I was quite perplexed at this, till I realized that it just sparked off a compressed charge, thereby turning the engine over.
So, I get a click from the relays behind the fuse panel when feeding power to the edu works, making me think that one of these relays is bad. Which one could prevent the ignition system / edu from working?
I know this sounds confusing, and I'm willing to try to explain it better if anyone cares to try to help.
Thanks in advance,
--Reuben
