 I bought this car NOT running,Carb was wroung one so i got the correct one for it.Hooked up all vacuum lines,new plugs,wires,cap,rotor,uni-points,oil&filter.Carb was dyno-tested and run on a motor,The guy that rebuilds them has done carbs for me before all have been good.So get everything hooked up and i have power to coil but no spark out of the coil going to the cap,not many wires to hook up and i have a 1972 cadillac shop manual to help out.Now what do i look for to get this car running?...Help please

Check for power at the red lead coming into the distributor.

How did you determine that you have spark to negative side of the coil? Isn't this HEI with internal coil?

You should be getting a pulsing ground signal on the - side of the coil when cranking. If none found, change the points and condenser.

Do you have pulse on the negative side when cranking?

Then you still have a problem in the points or distributor. That is what supplies the pulsing ground to fire the coil. Make sure the wire isn't shorted inside anywhere.

The post has insulating washers on it .Is is possible but rare to get the wire behind the washers vs between them which will ground it. What about the point setting. Glad to help you TROLL for an answer.

The wire is supposed to be making contact with the swinging arm and the related spring only. If it makes contact with the frame that is screwed down, it is shorted out. Also make sure your engine is grounded to the battery and frame.

Saw a lot of guys install the wire in the wrong spot....
One thought i had too is ...had many uniset points come out of the box and not start the car.
Not just Delco Remy but others as well..
Assuming they're installed correctly as the others have mentioned..take an allen wrench,open the distributor cap window and while someone cranks the engine,try backing off on the points to see if it hits/starts.Had to to this many times,if so,then set the dwell with a dwell meter..
A lot of guys that didnt have a meter would dial the points in until the engine misfired and then back em off like 180 degrees..not the correct way ...
