I know this is way off topic, but my son's 1995 Jeep Cherokee was running fine last night but when he tried to start it this morning, it wouldn't fire. When I came home this afternoon, we checked the plug wires. No spark. I was getting voltage from the coil wire to the distributor cap but no voltage to the plug wires. I think the ignition pickup has gone bad. If I change it, I'll need to pull the distributor.

How hard is this to accomplish? I know there are some of you on here more automotively mechanically minded than I. Thanks,
Chris aka Speck.
