It's your anti theft detterent system and crank malfunctioning. do you have the owners manual? if not heres a link I found for my Boyfriends 2002 2.2 I think I remember seeing something about how to reset it etc if not I definitely know theres videos on u tube teaching how to disable the gm anti theft starter issue. im dealing with no cooling fan turning and possible water pump causing overheating causing squeaking whining noise upon acceleration any help would be cool!https://my.chevrolet.com/content/dam/gmownercenter/gmna/dynamic/manuals/2002/chevrolet/cavalier/2002_chevrolet_cavalier_owners.pdf
