Could it be a VATS issue?

No dealers here in Las Vegas, NV will work on automobiles older than 20 years.. ZO6, 25 years old. Worked fine one morning, after driving 30 minutes, stopped to pick up mail, ignition would only come on, not engage starter.. After tapping the key it started up as usual..

As I've said a million times on this Forum a dealership is the LAST place you'd want to take your car to have it diagnosed !!...they only replace parts...find an auto electric shop instead...one of a few in Las Vegas is listed below.
