Bought 1987 Coupe about 4 yrs ago. Frequently car would time out and not start-nothing ,4mins would pass-VATS problem, and then start once 4 mins were up. Car failed to start about 2 months ago, great they can trouble shoot, found a code that indicated the ignition switch. Dealer replaced ignition switch for $424 and for 30 days the world was great. This time the car would crank but no ignition. Had car towed to dealer, the thing started. They kept the car for 4 weeks trying the ignition several times daily, no failed start. Once they said it did not start but when attempted again it started. Does anyone have an idea of where to start or had similar experience?!

 

Can't think of anything but you might post in the Corvette section of our sister forum here.

Do you have spark?
