If you are not getting spark from the coil to the distributor then I suspect the coil is the issue or you have an issue with the distributor that is not able to deliver the spark from the coil to the cap.

I am attaching the info from the manual that will help this system. Basically the coil gets battery voltage and then gets a voltage spike to get the high voltage needed to fire the plugs properly. Then this high voltage is delivered to the plugs through the distributor.

If you have not changed the cap, rotor, and coil, then this is where I would start.

Please let us know what questions you have and we can go from there. Thanks
