If you take the coil wire loose from distributor cap and hold close to engine ground, have a helper crank it, can you see a spark jump? If there is spark, then check the cap and rotor.

No spark. From coil in have current. From coil out no spark.

Maybe a problem with ignition module? Can you check for injector pulse, engine cranking?
