cavalier remote starter problem

Voltage sensing, typically, does not require a wire connection. The unit will know the vehicle has started by sensing changes in the battery voltage. The only condition being of course, is that your particular unit is capable of the Voltage Sensing feature. PURPLE / White from the PCM is the correct wire, so if your unit successfully has learnt Tach, then I second what Ispker wrote. Sit in the vehicle and take note of whether or not the security light comes on. Passlock II is a fuel shutoff Anti-Theft system, the vehicle will still start, but will die shortly after, due to the fuel cut off.

For the 3rd time, the security is succesfuly bypassed, the light does not come on the car starts and sounds like it is running well until the remote starter turns the car off and then tries again, it does this 3 times then stops.

I might be able to help you. I have a 02 cavalier. I instead have the 556L which is an updated version. First connect your tack wire to the white wire running off your ignition module. where do you have your other remote start wires conneccted?
