Long story short...With ignition on, and from under the car, i can jump the startrer and car fires up and runs for about 3 -5 seconds and shuts off..Wint start with key at all..cleaned chip on key, still no go..Any help would be gratly appreciated..

Not exactly sure, but i think the anti theft chip in the key runs through the body contol module... might be a good place to start
