Sounds like a VATS issue. That little chip in your key. I'd say to start out, try pulling the PCM Bat fuse for a couple minutes and then try starting it once the PCM has been reset. Even if it does start though you're going to need to look into fixing the key. Search for VATS bypass if you just won't to get rid of it so you don't have to worry about it again.

 

i just pulled the pcm batt fuse and the pcm ing fuse so ill wait to the moring to see,. i know its a vats issuse or the tranny not thinking its in park or something.. somebody please help me this is my baby

 

You can bypass it or try to fix it. Shoebox has several good fixes on his site.

 

how do i bypass the vats? can i buy a module or something ?

 

Threads about "security light" are in the general tech forum. A search there should provide you with a plethora of threads dealing with it.

Unplugging the connector under the steering column should allow it to start, thought the security light will remain on.

 

Your homepage needs to be a sticky. There is enough info there to stop a lot of posts.

 

You know I hate stickies.

 

Hey I had that problem, car just flashed security. The problem is apparently quite common. There is two really thin wires in your steering collom and where the key tumber is. After a while they tend to wear out and break. You have to remove the air bag and get a steering wheel puller / ring pliers to get to the wires. Its not hard to do just time consuming. I asked if I could solder and heat shrink the wire back together but apparently the resistance value will increase and in turn not work. Thats if that is in your case the cause.

Did you try your spare key if you have one?

 

today i went got under the car jumped the starter the car start and its ran but its doesnt run long as soon as i left of the gas the car just dies. so now i know the security system is engauged. how did it get engauged? is there any way to get the whole system off? went to dealer they said they dont delete vats so i dunno. they wanna charge me 311 for a sensor and 154 for the lock switch. so i dont understand the bypass tho can ne1 help me on that or what can i do?

 

From the best of my knowledge you can test your key with a volt meter. I believe its the setting on ohms of resistance. I think shoebox has a page about that on his site. Another way of finding out what could be wrong is by taking your steering wheel apart. Like I say it is apparently common to go on any type of chevy (key tumber)

 

yes i think that that might be it.. today i went to gm and they told me about some sensor under the back of the dash i dunno,and why i was there i had them check my key they said the key is good.. is it hard to tear apart the steering wheel? what whould u do in my case send it to gm or tear it apart myself?

 

Well to be honest I am still learning about car mechanics and I found it quite easy... Basically I think there is four bolts on the back of the steering wheel. Remove those after of course disconnecting either the battery or the air bags. I recommend the battery!

Then I believe you pull out the air bag module remember how it came out and unplug the electrical connectors... I was cautious about that you dont want to damage the coil in it by dropping it etc.

Then I if I remember right there is a spring clip that holds the locking mechanism in. Then you need to unbolt a nut and use a steering wheel puller which is not very expensive. I think I payed $20 at most for a decent one. Important!!...... Mark the steering wheel bolt and wheel BEFORE you pull it off so you know where it was when you go to put it back on!

Inside after that is the starter tumber. I cant remember if it is bolted in but it came out quite easily. You will see the two wires in there and one probably will be broken. I think there was clips on the wires, just clip the new tumber in after removing the old one.

To put it back together just do the revers of taking it apart. Took me maybe half hour the first time. There is torque specs on tightening down the steering wheel nut but I didnt bother.

Now the bad news.... When you replace the tumber you have to get new keys to match it. I think when it was all said and done it cost me about $140.00 and chevy wanted over $400.00 to do it.

Its quite easy and if you need help I can message you or whatever. The coil in the air bag is delicate but nothing the average person cant handle. The Haynes manual has it all in there.

 

I also just read that Its also recommended that you wait at least 20 minutes after pulling the fuse/disconnecting the battery. The DERM module stores power so that the airbag can be deployed if the electrical system is damaged. It takes a few minutes for the storage capacitor to bleed down. Wished I new that when I was working on it. Place the air back down facing up, that way if it goes off the impact will be less. The chances of going off are not that great, just better safe then sorry!
