Hard to see through the rust and grime but as you say the 240Z condenser is outside the cap, and connected to the points system.  Older US cars used to have them inside.

Found a 240Z video that looks promising.

 

Here's another video that might be interesting.  Shows the combined points and condenser.

So I had a look and what I said is correct, solid black wire from neg post on coil to spade on distributor. It should be along side a yellow wire that goes to the temp sensor right above the distributor. 

I bought an asking price $5,000 for $2,000 because of that black wire to the distributor. He mucked the car up really great without that wire. One of my all time best buys.

He didn't know squat about Datsuns either. Fords only.

OK.. to all - here is what happened =  hopefully helps other starting a car after many years.

1. changed ignition coil

2. changed balast resistor

3. new plugs

4. sanded points and cleaned in distributor.

put some gas in the spark plug hole and presto.. UP AND RUNNING.

check water line for radiator a few mins later and the out put was dry,..   stopped motor - water pump ok/

how do you fill the cooling system?

just fill up rad? backfill it?

also - dash shows voltage.. does that mean alternator ok??

put new radiator in.

water leaking out of arear where water returns to rad so looks like water circulating ok

ran for a about 15 mins.. car warmed up a bit..

 

 

 

 

I don't hear all six, but not bad.  Lots of work ahead but at least you know it will probably move once you fix all of the other stuff.

YO Zed.. how can you tell its not all 6...???  and why would it be less then 6??

 

ALSO-  the key that turned the ignition was an uncut key ( cylinder obviously dead ).. but when we tried to turn the car off the key would not turn it off WOOPS>>>

why would that happen?? bad  key ignition unit? a  ground?   is that a normal problem??

-No spark(ran wire from battery to ignition coil and got spark)  This is why the engine won't shut off.

 

I ran a wire from starter motor to ignition coil - will that cause car to not shut off???

if so- how do i run it??

The sound.  Compare.

 

The front carb fuels the first 3 cylinders. Rear carb fuels the back 3 yo.

 

OOOHHHH  - so one carb might have issues?? no fuel???  check fuel line?? blow em out?? our gas was coming from a raised funnel like an IV tube.. not from fuel tank - so maybe gas was getting used up by first carb??

 

what about car not shutting off when key is turned off????

Check the exhaust manifold temperature, one end is probably cold.  Front or back.
