I have a 1993 Storm and I had the same problem with no Spark. I replaced the plugs, plug wires, cap, rotor,and the coil and still didn't have any spark if you have done all that I would say that it is the whole distributor itself, If it is super rusted im sure this is your problem. My mechanic told me that they are supposed to have a gap on them somewhere and if that gap rusts shut they will not work.Anyways $300 and a new distributor that solved the spark issue on my 93 geo storm. This is very simple to replace it took me about 5 minutes All you have to do is pull the cap off then I think it is two more bolts to take the distributor off. also it will need a brand new cap for it because the old one wont fit right if it has been shoved on ur old rusty distributor,
