Heres my situation...
I have a 91 deville that all of a sudden died out on me yesterday. When I try and turn it on it will not turn over, no click/crank and no start....In the recent past it has been giving me trouble when trying to turn it on. It would click but not come on so I would have to turn the key a couple of times to get it to start...6 months agoi replaced the starter because I knew that was the problem.....Just yesterday I took it out and got it tested but it was good....A friend who is knowledgeable about cars told me it most likely is the neutral switch....I thought it could be the ignition switch....Anyone had, and correctly diagnosed this problem in a vehicle of thiers? Any help would be appreciated!! Thx.........

 

My 91 deville sometimes does that, but if i just turn the steering wheel a little, it starts right up.. weird. Hope you figure it out.
