Unless PATS is disabled in tune, you need the working transponder key for PATS to communicate with the fuel injectors / fuel pump.

How can i tell if it is yhe right key.

In my car (a 98, but also Gen 2 PATs), the wrong key will turn the engine over but it won't start. The "Theft" light on the instrument cluster flashes when this happens as well.

Turn the key to the run position but do NOT crank. Does the theft light go out after a 3 second "prove out"? If so, this means that the PATS key was read and accepted.

Does the theft light continue to flash or on solid? IF so, then the PATS key read failed and the motor will not start.

Note, the 1999-2004 model year PATS does NOT disable the fuel pump. So a PATS issue will not cause a problem in the fuel pump operation.
