I have a 1994 Olds 98 and yesterday when I went to go somewhere it would not start. I ruled out electrical because it did absolutely nothing, even when connected to my battery charger. I looked in my handy-dandy repair manual and that led me to believe that the PRN switch was bad. It was actually very easy (30 Min) to change and that made all the difference. Car started right up. So, if your car won't start and it isn't electrical, the PRN switch should be an option to check.
