First check the 12V side of the coil. I know there were problems with '82 where the fuel pump relay was moved and the 12V from the relay to the coil would short out.
Easiest way to test the engine would be to jump the 12V from the battery directly to the 12V side of the coil. This will give you spark (I've had to do this a few times to limp a few wrecks home).
CIS is easy. Rig the fuel pump relay so it connection so you get constant fuel (12V direct to the fuel pump - 1 jumper), connect the 12V to the coil and turn it over. It will run, but I would not suggest driving it this way for a long period of time. Don't forget to disconnect the fuel pump and coil after you shut it down, or you could end up with a surprise :)

Subject: [Tech] ...No Spark at Coil
OK guys,...I'm going to throw this out to you all and see what happens.
Here is my problem. The car is a 1978 with CIS. What I have for sure is
no spark coming from the center tower of the coil. I hooked up my timing
light today and noticed no spark at the plugs,...so I hooked it up to the
wire going from the coil to the distributor........still no spark showed.
Where do I trace this thing from here? I really need this car running so
that I can pull this motor out. From what I can tell,...the wires on the
coil are hooked up properly,....anyone? anyone?
Lastly,....the starter is turning over fine,.I DID check resistance on
the coil,....that seemed OK,.........hmmm,....is there a way to check
whether or not power is making it from the battery to the ignition switch?
(if that is where it goes?),...then out to the coil?
Many thanks,.....again!
Chris
