It could be many things that cause no spark.When Mine didnt have spark it was the module located in the bottom of the distributer. You will have to remove the distributer and take it apart to access the module as it is in the bottom. Mine was oil soaked. I tried the easy stuff first like the coil and rotor but the culprit eas in the very bottom of the distributor and cant be seen without R&R of the distributor part cost was about $40-50 bucks
Good luck
Dont forget to mark the distributor to get it back into the engine properly.
Put a couples cratches on the block and dist housing for alingment and take note which way the rotor is pointing.
PS
I also adjusted my distributor, retarded it, so my car would run on regular gas instead of Premium without knock. You loose a little pep but it has so much power you dont even notice it after a couple weeks and it passed Mass. emissions with flying colors.

Spark plugs are easy to change. One disconnects the batter and spark plug cables, and removes the old spark plugs. Next a person puts in the new spark plugs, then reconnects spark plug cables and the battery.
