How long since tune-up. plugs--plug wires--cap and rotor. Any applicable mil codes? Did you visually check for spark at the plugs?

Use a test lite on negative side of coil, engine cranking, there should be a pulse? If no pulse, suspect the ignition module or pick-up coil. There should be primary voltage at the coil with key on.
