I have a bunch of information on the V6 VATS
First is that GM used 3 1/2 different VATS on these V6 cars --> these are not settings
#1 is VATS 2
#2 is Passlock
#3 is PK3
#3.5 is PK3+
VATS 2 on 3800 F-body's disables the starter signal and is not an input to the PCM
VATS 2 on most other cars send out a signal on 229 circuit to enable the fuel
Passlock on most V6 cars disables fuel, but when the PCM started to control the starter it then controlled the starter. This is Serial data.
PK3 & PK3+ work similar to each other. This system is serial data and disables both
From the factory you can see that they had multiple settings. These are not as the way TC has them labeled
Please fill in the attached VATS document with the setting you find from the factory and known good disable settings
My copy on the house PC must have more filled out
