i noticed in your picture showing a splice to the voltage regulator from the ballast, you used a "scotch lock" [or whatever they are called] i'm not a fan of those, as they can cut the wire strands when they are attached, and can allow moisture to wick into the spliced wires causing the dreaded "green death". just my opinion from years of repairing wiring harness issues. your mileage will vary.

I had the same problem your experiencing a few years back with my 70 Satellite...
It didn't always want to start as it should and seemed like there was no power in the start location of the switch...
Occasionally you could turn it over and flip the switch back to run fast and it would fire...
It turns over just fine but never tries to start...
Mine ended up being a bad ignition switch not always supplying juice to the run 2 terminal...
Sometimes it was fine...other times it didn't start...
You can always turn the key to the run position and jump the starter relay and it will start...provided everything else is in working order...
All ignitions in my cars I've done in the past ten years I scrap everything original and run all aftermarket components...
My last 3 builds are all full MSD...
No more issues...
...FAFO...

OMG!!!! 😳 Electronics 101A teaches that every connection is a potential problem and to avoid them whenever possible. You have some rewiring to do IMO. And the U-haul connectors (scotch loks) as mentioned GOTTA GO. They're right up there with the bolt on .99 cent battery cable ends EDIT : Mr. Kunkle was referring to the coil sparking when the male terminal was momentarily grounded. With regards to the ECU, I would get the charging problem resolved as 16V will potentially fry them

Not sure what you have going on with that wiring. The voltage regulator looks older, you may want to replace it with a modern solid state one. That being said, newer parts these day are not always better than older ones that are still working well. Do not buy the reproduction early style voltage regulators, they are junk.
My brother had a similar problem to yours years ago and it wound up being the ignition switch. Running a 12 volt source to the coil should have eliminated that as a potential problem though.
Modern ECU replacements leave a lot to be desired. Jegs sells a decent replacement. Their orange box is good to about 5,500 rpm and their blue box is essentially the old chrome box. Bill Evans can also sell you a reproduction engine harness that is made for electronic ignition.
MSD blaster II coils are not recommended for use with stock style ECUs. They are also not meant to be mounted horizontally. I would replace the coil if you buy a new ECU. Bad grounds are also a common issue with ECUs. I have a ground strap from the back of my block to the ECU as an added fail safe.
When you check for voltage, always jiggle the wires a bit and see if the meter changes. We’re talking about nearly sixty year old wiring here, might detect a broken wire or bad crimp connection.

IE: Ground the mail terminal on the ECU side of the distributor distributor connector, and the coil wire should emit 1 spark every time you ground it With regards to the ECU, I would get the charging problem resolved as 16V will potentially fry them. I also agree with the VR upgrade. There will be no resistors on the back of an electronic regulator.

Slow progress. I have ordered a VR (Echlin from NAPA) and should be here tomorrow. Still working on the splice issue.
I checked the 4 pin ballast. I found that the 5 ohm resistance pins are on the bottom and the 1.5 resistance pins are on the top. Does that make any difference with the wiring and in the start / run operation?
Thanks.
Additional note. I have a 4 pin ECU and a 4 pin ballast resistor. I can find wiring diagrams for a 4 pin ECU and a 2 pin ballast or for a 5 pin ECU and a 4 pin ballast. But nothing for what I have. Does anyone know where I can find a wiring diagram for my setup?
BTW I no longer get a bump when I release the starter.
