My 240z has been giving me trouble for way too long. At first I was having hesitations at highway speed or during aggressive acceleration. On reddit it was suggested that may have been a distributor issue. So I swapped out the points and cap and condensers and whatever else. Spark Plug wires swapped too. Still problems.
So I headed to the forums and decided that the distributor itself was the issue so I swapped it to an electronic distributor from a 280zx. Did some mild re-wiring, cut out the ballast (BW to GW and BW to terminal on coil) soldered and we were good to go or so I thought. It started up like a million bucks and drove off no problem. Go to get gas and Boom it leaves me stranded no spark.
I figured well it was an old coil maybe that was the issue, I change the coil to a NGK 240z coil. Starts up again great, go to get on the highway it dies I got nothing at the pedal. Cools down a bit we wiggle some wires it starts then we head off again, get home to check some stuff, no spark. Then I changed it to a new 1980 280zx NGK coil and swapped out the e12-92 module on the distributor to an e12-80 IC, Still no spark. I wired directly from my battery to my new coil skipping over the ignition. Still no spark. Re-did my negative battery terminal to my firewall and my negative to the engine/starter. Re-did the wiring between my coil and distributor and double/triple checked that I did it as per the wiring diagram. See here: https://imgur.com/gallery/G7adJPd
Wtf am I missing. The engine turns over so I know I got enough battery for that. I've been checking spark right at the coil. I skipped the ignition and key so that can't be the issue. What am I missing here? Why can’t I get any spark? I’m so frustrated with this car right now. Any help is appreciated

Why do I have no spark?

So I swapped to the e12-80 module no spark. Switch back to the e12-92 module and tons of spark go for a drive start to give it and it dies. Wait a bit and wiggle the wires on the top of the module and it starts. What you think is happening?
