Hello,

The key has the chip for the anti-theft--may not be the anti-theft.

TPS (Throttle position sensor) - Bypass by holding gas pedal down and starting.

Hope this helps--

Sorry no easy solution to this. and we can't give out that info anyway.

not knowing what the prior owner did, you do have a problem, you might try to remove that fuse, disconnect the battery and re-try it, if still NO-START and the THEFT light is flashing it because it lost memory for the key code and will have to be recoded at your dealer

the anti-theft system will have to be reset to enable the car to start

you need to have the key reprogrammed by a locksmith or the dealership. it will only start and stay running with the original or reprogrammed key.

how to get the anti-theif lightoff

You may have a faulty ingition. Otherwise you have the very common GM anti-theft system. If you have a flashing anti-theft light with key in igniton, then this is what you should do:

Put key in ignition, turn to ON position (Do NOT Start)
Leave in on position for EXACTLY 10 Minutes
Then while watching the anti-theft light, as SOON as the light turns off after 10 minutes, START CAR IMMEDIATELY after light turns off.

This will reset the anti-theft
