HEI coil issue?

It does , just not a coil wire
The spring & the carbon / graphite pin under coil to rotor
Op said installed another distributor,
Still no spark ,
I would say ground or No 12 volt in crank .
Does the rotor turn , as in when you pull cap in different spot after cranking ?
If not is it possibly a really unusual issue broken cam teeth ?

 

Okay so there is power at the distributor when cranking. It’s actually drops from 12v to about 10v while cranking. So what is that telling me?

Next going to remove the distributor cap and try cranking it again to see if the rotor is turning. Do I disconnect power to the distibutor when doing that, or leave the pink wire connected?

 

You don't need to disconnect anything. You really only need to crank it long enough to see if the rotater actually rotates

 

Okay just checked and the distributor/rotor is turning when I crank the engine with the distributor cap removed.

 

Have you actually tested the ignition with another sparkplug grounded to the block ???
