My 1999 pontiac grand prix will crank but wont start its got spark, it getting gas but it still won't start
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~
