Having no spark & noid light only lights once at start of cranking, it kind of tries to start sometimes but didn't "try" to start with spark tester on at all so I guess intermittent spark.

 

could be your opti spark plugs wires with spark it can be so many things ,this is last I guess

 

noid light should blink when trying to start the engine. it very well could be opti. are you getting power to the pink wire to the coil when the key is on?

Well, in my quest to change the optispark I have nearly given up. There is no possible way for me to remove the harmonic balancer, the sway bar is too far in the way to use any kind of force to try and beat it off and a puller is going to pull the hub as well because there are no threaded holes in the pulley itself just through to the hub.
