That was going to be my next question; if you had a remote start. There should already be a resistor and a relay or a self-contained bypass installed under the column. The VATS wires are very tiny and can be difficult to connect or make a good connection. I've also seen the added resistor(*) become outside the 5% tollerance allowed after some time. You could defeat the VATS all together by soldering or connecting the correct resistor to the VATS wires if you don't mind not having the factory security system anymore.
I would recommend temporarily connecting the correct resistor(*) just to verify that it is in fact a bypass problem rather than something else such as an ignition switch. After that you can:
1) Diagnose and correct any wiring or connection problem that might exist. Once you remove the trim under the columnl, it might be very evident why the system isn't working. You might see a loose wire or two.
2) Remove everything related to the bypass and permanantly connect the correct resistor.
One additional tip I have for you. Most remote starters come with what I call a "resistor pack" which contains 1 each of the 15 resistance values used in GM systems. If the starter is installed into a car without VATS or similar system, the resistors go unused. They usually pile up in the installer'* toolbox. If you know someone who works at or are friendly with a retail store that installs remote starters, ask them to give you a resistor pack. This will allow you to use only one resistor rather than having to use a combination to acheive the correct resistance.
