the coil receives power all the time with key on, the ground side is toggled to make the coil spark, you shouldn't be able to detect ground unless its running and if you do ground it while running you will find it will die. the pickup coil, and ignition module in the distributor control the spark, and injector pulse, if it won't spark, and its the origional distributor, I usually just replace the whole thing with a reman from carquest, napa, etc, usually 100 to 150 with exchange, its cheaper than replacing the separate parts, and all new you can't go wrong. this is a common problem with any mid 90's gm v8

Yes it is your problem starter isn't engaging however you will need to have it replaced.Properly jack up car have two axle stands properly support the car with those in position.Disconnected the battery before attempting to start removal of starter.Now located the starter beside your oil pan with the positive battery terminal going to it and disconnect it along with the other solenoid wire.Now remove both starter housing bolts and pull out your starter.Be sure to make sure all wires and bolts are tight when you reinstall your used or manufactured starter from your choice of purchase.Merry Christmas.John
