if you checked the dizzy wires and there is electrical current going there you're 1 step closer to finding the issue. I'd remove the plugs one by one, place them on top of your rocker cover with the lead connected - making sure the spark plug touches the cover but has a small gap between the point and the rocker cover. Have someone else crank the engine over and check for a spark between the tip of your electrode and rocker cover.
If you can't see a spark - that lead is shot and needs replacing. Also replace spark plugs.

If you have a spark there *and i suspect you will* - im putting it 99.99% you have something up with your fuel system, either the regulator OR quiet commonly a fuel pump relay could be shot. When you turn the key over, can you hear the fuel pump prime? you should hear like a zzzzzzzzz when your PGM-FI light comes on and then stop once your PGM-FI light goes off. If you can't hear your fuel pump you might have to remove the rear seat to hear better then 1: your relay is gone 2: your fuel pump is acting up. Im putting it more towards your relay - its an intermittent fault they seem to develop over the years.

Give that a go...
