I have a 99 sunfire gt that starts but chokes and dies. the altinator, battery wireing to the alt and batt and ground check out good. This started out when I disconnected the batt to replace the altinator. The fuel system checks out good too. The warning lights and the theft lights on the instrument pannel have been a problem for this car for awhile and when it was running a relay had been buzzing in the fuse pannel. I got it to start and run for a week but It died again. Any Ideas??
