Did he program your pcm with the security? By the sounds of it starting and stalling after three seconds, the security is not allowing it to keep running. even if he doesn't have security the pcm is still looking for the security codes to keep it running. Either way i say that it is the guys fault to not check into compatibility and/or not getting it programmed properly. changing modules now of days is touchy because the computers usually only get programmed once and then can't get changed until they get sent back to the manufacturer .
