Yes its a good rythmic spark. I have kept a battery charger on all the time when working and battery showing full charge. So possibilty of weak coil?

Could be. There are resistance tests that you can do on the coil, and the auto parts stores have testers for them, but at best, either way is not too reliable. What kind of rapport do you have at the auto parts store? Usually they won't let you return electrical stuff.

Can it be a plugged catalytic converter that would cause issues like this?

Orange spark before, blue spark now, we're making progress very slow, but progress none the less. When you disabled the ignition and fuel pump to check the injectors, and when you sprayed carb spray in the air intake, that fuel is still in the cylinders, and might be flooding it now. Hold the throttle to the floor and crank it. That will shut off the injectors until it starts, (if it starts) If it's flooded, it should only take 4 or 5 seconds of cranking to clear it out. Try it, see what happens. Just for grins and giggles, while you're cranking it, have an assistant put a hand over the tail pipe to see if its pushing out air. (restricted exhaust????)

I seem to have good exhaust flow out tail pipe. I can try to disconect exh. At connection by firewall but seems to have good push of exh. With hand over pipe. What would i look into next
