Vats problem! Help!
This is a from a post I did about a month ago
"When the light is on while the car is running the VATS is in Start Default. Meaning the system sees an error but will start the car. The VATS can at anytime revert back to Pass/Fail (normal mode). In this mode if the system can't read the proper resistence from the Key the Security light will usually flash (while the key is turned) and the car will not start. Most of the time the light will remain on after the key is turned back to the off position, when the light goes out (3-4 min cycle) you can try to restart the car.
You can go to the dealer and have it fixed at a cost of $300+ or do the VATS Bypass for only the cost of some resistors."
The issue you have been dealing with is not unique, many of us have been there including myself. I actually dealt with this for a few years before finally doing the Bypass after the car did several 3-4 min cycles and never started. I came back 2 hrs later took the car home (yes it started) did the bypass and never looked back.
At this point you don't have much to lose by trying the Bypass.
