No spark the engine cranks but no start. Died while driving. Horrible sulfur like smell after it stopped. Good from battery to distributor cap. Then no spark from no. 1 spark plug?

Replaced the battery, alternator is good, replaced the ignition coil, modulator, condenser, distributor cap, rotor. Have no spark at no. 1 spark plug. Has power up to the distributor cap for sure (did not replace the pick up coil)

Have no spark on no.1 what about the rest? Still no spark-check and test the distributor pick-up coil resistances and for short to ground
