Painless no spark

Iím sure these questions are getting old. Iíve been trying to figure out my no spark issue. I got a new coil. Tried another ignition switch. Tested wires. I am getting my ignition module tested today. My question is, should I have power to the ďsĒ side of my starter solenoid and when I checked power to my neutral safety switch I didnít have anything. Could those be issues?

The S wire at the starter relay is for cranking the starter only. Has NOTHING to do with whether or not you have spark.
You should only have power at the S wire (Red w/blue) when the key is in the START position and at no other time.
Only the Brown "I" wire has power with the key in the ON position and is connected directly to the Red w/green wire that powers the ignition coil. But not the ignition module.

Is the starter cranking? Or do you have both no crank and no start? You should really continue this in the same thread you already have on this subject rather than start over or we're just going to be asking all the same questions that have possibly already been asked.
Now that I've said that, you DO have another thread on this, correct? Or are you separating a no-spark issue from a no-crank issue?

It’s just a no spark issue and now rear lights but I need to check bulbs on the rear as well and grounds.

I used a multimeter to check for power.

I’m able to get the motor to crank but no spark. I am getting power to the coil,ICM and starter solenoid. But no spark. So the only thing I’m not getting power to is my rear lights, and NSS.

Make sure your distributor is spinning with the engine. Sometimes the pin shears or the gear fails due to material mismatches with the cam material.
You have power to the positive side of the ignition coil you said. Also during START/CRANK? Might check that too if you have not.

And you have power to the ignition module too. Which wire(s)? It actually does not always matter whether it's to the Red wire or the White wire, but it should be to one of those wires. Red is supposed to have power with the key ON and White is power with the key in START.

And speaking of modules, do you now have a Blue Grommet model? If not this might be an issue since your harness is designed for the Blue type.

Are you getting spark " out ' from the coil ? If so but you still don't have spark to the plugs then it's either a distributor rotor issue , distributor cap issue or the distributor ground wire isn't connected or broken inside the distributor .
