Theft System Problem.Car may not restart(Message).
PRN321 is flashing/blinking-No SECURITY Light is on.The car attempt to start,it does crank but won't start.
I have measured those 2 white wires(VATS) and they have the same Ohms(2.35) like the ignition key.
I have checked /cleaned the battery terminals and fuses already.
I did the Pass Lock Relearn unsuccesfully.
Same message:Theft System Problem.Car may not restart and PRN321 is flashing/blinking-No SECURITY Light is on.
Please Help!!

sounds like your car thinks it is being hi jacked....lol..... can you reset, with remote your anti theft message? or discinnect battery, negitive for 20 min, reconnect and see if that might reset your anti theft

I have the same problem with a 1999 sts, the injectors havent got a power or earth feed,and the secruity light is on,if i add fuel through the air intake the engine will run have you any idea's or sorted the problem regards julian

the resistor in the key disarms the starter if it cranks but only runs for 3 seconds its the TDM ..........bypass it ....build a little square wave generator and no more problems!
