cranks but no spark at coil

Thanks TB. So which contacts? Rotor to cap? Or distributor leads?
Not all the time but most times when I turn key off I get the "kickback" if that makes sense?
If my helper comes out and turns engine over while im under the hood, I can hear a "click" when they shut key off.

I admit the wiring isnt the greatest under there but its not "terrible" or totally butchered.
Its handy being able to use known working parts from cuda and/or using it for reference. One thing that is different is the starter relay. I can't simply swap to check.
Im unsure how to test it, any ideas?
Its a 7 blade and heres a pic.
Thanks TB, I will post test results tomorrow.

Check you distributor connector Steve.
I have seen those contacts inside them spread open and not make contact.
If they don't make contact then nothing tells the box to fire the coil.
Since it fires when you turn the key off you know it has power available.
It sparks when you turn the key off and that is what the igntion box does, (shuts the ground to the coil off momentarily to make the coil fire) so that pretty much narrows it down.
