1993 Chevy Camaro Z28. Question : I have had occasional problems with my '93 Z28 not starting. Once in a while when I turn the key to start I simply get a heavy single click sound coming from the starter. If I repeatedly turn the key the car eventually starts. I've had 5 brand new starters installed over the past year. I have a extremely heavy duty (brand new) battery. Any and all grounds as well as positive connections under the hood have been cleaned and reassembled, And an additional new ground added directly at the starter to the body put in place to ensure proper ground. Same effect.
One thing eating me up is that the sole ignition key is very worn, and I was thinking this may be causing the problem. I have been to two highly regarded GM dealers who can retrieve the codes to make a new key, but cannot read the VAT code using their devices. Is there any other way to get my VAT code? Both dealers contacted GM directly over the web to do so but for some reason my year Camaro, along with similar year Corvettes VAT codes are not available.
Is there some way to override the VAT code requirement? Help! What are my options? Could my worn key with a worn chip be the cause of my problem?? In addition, sometimes while driving the "security" warning starts flashing on my dashboard then goes away.
Answer: Well, first off, if the dealership cannot get you a new key, I don't know how else to do it. The key would not be your problem starting the car anyway. It could be the problem with the security light flashing then going out. A worn out key will do this.
Another common cause for that light is that the small wires on the back of the ignition cylinder are broken. But that would not be your starting problem either. If you are completely sure that all the wiring to the starter are good, then you may just be getting cheap, inexpensive starters. But, you need to check the wiring from the positive cable all the way up to the junction block.
Also, from the smaller purple wire all the way back to the neutral safety switch. You could also have a bad neutral safety switch. Next time this starting problem happens, hold the key in the crank position and move the shifter from part two neutral to reverse and back with your foot on the brake to see if that helps. If it does, then the neutral safety switch is bad.
