Maybe a problem with cap or rotor? Does the rotor turn when you crank the engine? Any applicable trouble codes? How long since a tune-up?

If the spark is getting from the coil to the cap, then the problem lies in the distributor somewhere. Missing or defective rotor? Rotor not turning inside distributor indicating either a broken distributor shaft, distributor drive gear, or cam gear.

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.
