Default car wont start!

battery is reading low on the cluster.
radio , lights and everything comes on though
no sound at all not even a clicking noise when i turn the key.
I'm going to get a battery but is that my only problem or does this sound like a bigger problem?
i would think that if my battery wasn't strong enough that the radio and stuff would turn on. need some help though thanks

Clean your terminals first. Same happened to my third gen. They were just dirty, cleaned them up and no problems since then.

Get your battery tested. Like stated, clean the terminals, make sure they are tight. Check your grounds.

may sound dumb, but make sure your car is in Park and not Drive. Also make sure to reset your alarm it might be tripped but not going off.

Is the security light flashing when you turn the key?

I mean is the security light flashing once per second when you try to turn the key?

Then you have a VATS issue. For some reason the BCM is not recognizing the pellet value of your key, therefore it is not grounding the starter relay. Majority of the time it is bad contacts in the lock cylinder in the steering column. You can go to GM and get the cylinder replaced, or you can bypass VATS with a resistor (easy to do).

I agree, its probably your VATS, you can bypass it pretty easily. I had to do mine a month back when my car wouldn't start. My brother is a mechanic and did mine, but it only took him 15 mins and $2 worth of resistors from radio shack. There are a few good posts on here if you do a search on VATS BYPASS.

How would u do that? Would u get a resistor as the same value as the key and just bridge it?

Pretty much. There is a litte two wire connector in an orange sheath runing to the steering column. One wht/blk wire and one ppl/wht wire. Splice in a resistor or resistors in series to match the resistance of your key conecting those two wires and you're good to go.

That's tight. How can u find the reistance on the key?

With an Ohm meter. If you don't have one, someone at Radio Shack should be able to measure it for you.

One lead on each side of the chip/pellet on the key.
