Ok. Power to the coil is different from the coil supplying a spark. Use a well insulated Phillips screwdriver. Pull the coil wire from the distributor and insert the screwdriver into the boot. Hold the screwdriver shaft about 1/8 to 1/4 inch from a good ground, and have someone crank the engine. You should see a strong, snapping blue spark. If not, replace the coil.
If it is an HEI coil (the kind mounted on the distributor cap) disconnect the wires and measure the resistance across the coil and let us know what you find.
