You don't say what year you are having the problem with. If it's a later model year, I had that problem and it was the ignition control module mounted behind the coil.

According to the factory manual if you have voltage at the coil and the coil resistances are good then you disconnect the high voltage wire at the distributor and hold it 5 mm from ground and crank the engine to see if you get a spark. If you don't then you replace the module.

According to the manual coil resistances should be 0.75 to 0.81 across the primary and 10-11,000 from primary to secondary.
