If my VATS was messed up wouldn't my car not start?

You probably need a Tech2 to pull the code and clear it.

Do those code readers remove the security light? I thought they only did SES lights...hmm i'll have to stop by kragens and scan and remove it.....

yes, but the security is a warning to you its about to happen, your pcm is in pass fail mode right now, its only a matter of time before it quits on you, do the vats bypass, it will be worth not getting stranded and your light will never bother you again

had two f-bodies i've had to deal with problem

there are different levels of vats...you can try to clean the pellet in your key with an eraser but most likely you just need to do the bypass or get it fixed inside the key cylinder. It's a really easy and cheap fix......$5 and an hour if that. I would just bypass it and be done with it.

Anywhere a write up on how to do this?

Ok so once I unplug the old resistor, what do I do with the existing wires? replug them in? or electrical tape them.....help a brother out

Also one other thing just an FYI, my security light isn't blinking as some peoples in that sticky.....it's just staying solid, does that make a difference?

If the system isn't reading the proper resistence from your key it will flash the Security light while your turning the key. If your light is just on Solid then it's detecting an issue and it may still start the car.
Mine acted up sporadically for years before I finally just did the bypass.

just follow that sticky that's linked in post 2....it gives you pretty much a step by step. Basically the wire runs from your key cylinder down the column and goes to a plug. The plug then goes to the bcm. What you're doing is measuring the resistance of your key and then buying resistors ( gold band) that match the resistance of your key. Unplug the wire coming down the column and cut that plug off on the column side giving yourself a couple inches of wire. Solder or tape those resistors in a series(end to end)between those 2 wires of the plug you just cut off and plug it back into the plug going to the bcm.
