Re: Cant start (power issues)
To check if you're getting spark, pull the main high tension lead off the distributor and bring it within millimeters of the body or engine block, then crank the engine. You should see spark jump from the lead to the body/engine. There are test lights for checking spark too, but I usually prefer the cheap/dangerous method for all things.
But if you already know there is no power at the coil, you need to figure out why first. Given that the cluster isn't powered, I suspect you have missed a wire, wired something incorrectly, or shorted a circuit.
Photos of what you've done, and wiring diagrams for the 18R and car you have can help diagnose the issue.
Be sure everything that needs a ground is properly grounded.
