... so, what does the vats(vehicle anti-theft system) module actually do to shut the car down....fuel/ign.,or what,... I know in the wiring diagram it shows pin B6 on the ecm to be the key pass vats pin...and I'm wondering if I splice it to A6 (which is 12v to ecm with ignition on) will it bi-pass the vats module...it looks that way in the wiring schamatic....(the only thing between B6 and ign.12v is the vats module).I did an engine swap...I had the whole engine/wiring harness and computer..from the other car..but have no idea if the previous car had vats,.. and mine doesnt, and everything works fine except for the injectors..they do spray at start up....and if I pump the gas then it will barely keep running by fluttering the throttle...and I used a noid light to comfirm this...it quits flashing after the inital start up.....I replaced the control module/ecm(swaped proms)/pick up coil, and ohm'd out all wires involved back to the ecm injector harness and all checked out fine....so...do you think B6 vats is shutting down the injectors???
