In addition to VATS (the chip on the key) there is a Theft Deterrent System (TDS) on these cars. I will have to read up on the specifics again but basically if the CCM does not sense the correct sequence of door unlock, door open and ignition key turn to Start, the starter sequence is blocked. Since there may be an issue with the interior lights you mentioned, there may be a TDS problem going on.

Keep in mind that VATS and TDS not only block starter operation (the purple wire) but also turn off the fuel pumps and the ignition (spark) system. I will have to review the manual to get the specifics.

I will do some homework tonight.
