right out of the chute, am going to suggest the rather delicate air temp sensor is BAD~ https://www.google.com/#q=1999+Pontiac+Grand+Prix+air+tempera ture+sensor

Would that prevent my car from starting

well if it is telling the computer that it's cold outside will start to flood ya...and if it's tellin' the computer that it's HOT outside will run poorly or not at all...that is simply a guess...any number of things may be wrong here...but air/fuel/spark and timing...one must NOT be right~
