91 Camaro mileage: 74,000. Frequently (As in 3 times so far this week) this car will not start. All the electrical works, but no crank at all. New battery, 2 new starters, new alternator, 1-year-old air conditioning system. I have had it towed 4 times recently - every time it starts right up at the service station. Last time they kept it for a week trying to get it to not start. Yesterday I couldn't get it to start. I turned the key to on position, let it sit a minute, then turned to start and it fired up. Got to my destination, and it did this again. My fear is that whatever is happening will get worse, and I am deluding myself that the key has anything to do with it. The garage said I should not have to let the key sit in the on position to start. I am terrified of getting stuck some place, like gay days at Disney Land. What could be causing this! My local garage can't figure it out - problem is that every time it has been towed it starts! I just know I am going to get stuck out of town and be in a real pickle. I guess it be worse though, I mena; I could own a mustang...hahahaha

 

5¢,

Since your car is equipped with a VATS system, I'd check the key and ignition lock cylinder contacts first. Watch the SECURITY lamp on the dash when you turn on the ignition. What happens when it starts normally? What happens when it fails to crank?
