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.
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.
