It would be a lot of help to know the year of the car, and the provider of the tune.

Its a 99 grand prix gt and the new PCM is out of a 2000 Buick I got female the salvage yard. Numbers match but I wondered if the Buick being in an accident for some reason the fuel has been shut down?

Wait, why would you swap out a pcm from a Buick, was yours broken or what?
Hopefully someone else will chime in but I dont know about transplanting a pcm from a completely different vehicle... I know it could be the same motor but different security systems and fuel pumps/fuel delivery, electrical systems, etc

Just 'cause it zips doesn't mean it fits.

My PCM is from a Buick Park Ave Ultra. But it has been tuned.
