My security light is flashing as soon as I cut the key on, the fuel pump primes but the car wont turn over. I drove it to work this morning with no problems, cranked right up the first try. The we I tried to leave work this afternoon, it wouldnt crank, and the security light is flashing making me think its the VATS system acting up. I have tried 3 different keys all do the same thing. I have tried disconnecting the battery to reset the computer, that didnt work. And I have tried turning it on for 5 seconds then off for 3 seconds and repeat for 3 times(I read that somewhere to reset the vats), and that didnt work either.

Any help is appreciated, my car is currently stuck at work, and I will need it back tonight.

Thanks
Kevin C


EDIT: I just read in another post that you can jump the VATS. Does anyone know how to do this, so I can try it??

 

If you search "security light" in the general tech forum, you will find many threads on what you can do. There is also info on my Tech Page.

 

I have looked through both, but cant seem to find this problem. I have had the problem in the past with the light coming on, and I just wait 3 mins and it will start but this time, the light is flashing, and does so every time I turn the key to the on position.

 

If you looked through them you should have seen that the contacts in the ignition cylinder are either dirty and no longer getting a signal or that the wires in the column are broken

 

well sorry to say this but flashing security light is a pita dude i had the same problem mine turned out to be my key cylinder. mine did the same thing flashed changed my cylinder and bam she fired up.. ok but jumping the vats is used by resistors and there a pita to match up by key.

 

I found this write up on shoebox's website VATS Bypass

I guess I will go try this


Did you try the bypass first?

 

yea i tried the bypass and i kept getting wrong key pellet numbers. dude thats a quick fix u gonna have to chane the lock cylinder.

 

Well I did the bypass, and it cranked right up. Thanks guys for your help, and thanks Shoebox for all the GREAT write ups on your page

I used these two

try testing your key like this
then go to radio shack and buy a resister that correlates to the reading you had. Mine read 1.47 on the meter so I bought a 1.5 resistor and it worked just fine. If you need more info look here

my car did that today to me..i gues the remote to the car to unlock and lock was stuck and lock the car so it went off...i had to pull out a fuse and then put it back in then started right up..check that.
