Question about 2002 Pontiac Firebird
Not sure if it suddenly happened or what, but that little resistor in your key makes contact with 2 wires when you insert your key, they run down your column they can break over time and will keep your vehicle from starting...problem is you cannot just tie them together as your PCM is looking for resistance and it could be one of like 11 different ohms...best way to find out is to find the plug with 2 small(possibly yellow) wires and verify resistance with an ohm meter, without key you should read nothing, and with key inserted you should get an ohm reading...if you do not get any reading with the key IN...thats your problem

SOURCE: I havw a 1997 firebird
Been there: had broken wiring in the key cylinder -- wouldn't read the 'chip'. Dealer dinged me for a whole assembly, meaning a new key-cut .. and new IGN keys !
Learned later that I 'could' have bypassed the chip-reader with $1.59 of resistors from RadioShack ..
