I have a 94 GMC and when the ignition module goes out a spare will keep the need for a tow truck to zero. I have been stuck once and learned the hard way. I change mine every so often just to avoid any issues.

A prior owner had installed an ignition control module from a different manufacturer. Needless to say, I was having some running problems with the vehicle, which made me replace this component as a general "reset tune-up" of my ancient Chevy's ignition system. I replaced wires, this module, cap, rotor and plugs with all AC Delco components. I discovered that I cracked a plug when I allowed a timing light to get caught in the fan blade (this was, perhaps, not my best moment in the garage) and had put back my distributor a tooth off when replacing my oil pressure sender.Ho hum....Anyway, my truck had a hodgepodge of odd parts on it - BWD (I believe this is Borg-Warner stuff, sold at O'Reilly's), Autolite (!) plugs, some unknown wire set, BWD cap and rotor. In replacing all these components, and most especially the cracked #1 plug, I was successful in making my truck run literally like a new vehicle.Lesson? Be careful when you're working on your stuff that you don't introduce three screwups for everything beneficial you do, and use AC Delco stuff on these old Chevys as they are sensitive to the careless engineering of other parts makers.
