Nothing in the distributor on that guy cept a rotor. The primary is controlled by the ignition controller based on the input from the crank sensor which is off the flywheel at the back of the drivers side of the motor. Not too accessible.

I would verify that the coil isn't being switched by placing a test light onto the negative side of the coil and watching for a blinking light when the car is cranked. If the light stays on then the controller isn't grounding the coil. I might expect a crank sensor at that point but they don't fail often.

If you get a blinking light when cranking I would suspect a grounded or open dist rotor or cap.
