i have a 1990 gt, when my car is cold it starts right up no hesitation, but after i drive it and its warm, i start it and it cranks then--let go of the key--sounds like something is spinning-then fires and runs. And once in a while it cranks-sounds like starter is spinning and then never fires.
heres a video(this is one of its good starts) usually it delays and u hear that spinning sound longer, then fires.
