Thanks so much for your quick reply
when the car was purchased used, the dash readout read anti theft system activated the car may not re-start
although it did for about two months
did a turn up spark plugs, wires, filters and oil. I disconnected the battery to replace a cable end. The car would crank but would not start after I replaced the cables. I tried to reset the system using the door locks (both) they appear to work as I get the wait 3 minute message after doing so. I tried leaving the key on for 30 minutes and several other "reset techniques " suggested then I learned of the lock cylinder problem. It was bad.
Had the key pellet checked with the dealer, a key shop and with a volt meter it's an #11 at 4750 ohms ideally.
Bypassed the ignition lock cylinder with a resister pack of 1/2 watt resistors equal to that value. The display now reads starting system disabled due to vehicle anti theft system remove key. And then reads wait 3 minutes. Then start car. When attempted the car tries to start for a split second then won't and the whole process begins again.
I replaced the vats module on the advice of the dealers mechanic. I am getting 5 volts dc at the output for the vats module. Drops to 3.29 with resistors installed. Wiring harness and connectors to module and ecm appear to be in good shape, since the car was running when pulled in the shop I am assuming that wiring connection is not the problem.
Re-set the computer and cleared codes before hooking up new module installed it as per the directions provided. Still get the same conditions and read out.
Any help you can offer would be greatly appreciated
