my 2009 aveo 5 LT, M/T. Engine won't turn over. tried to push start and NG. Battery is charged. when the key is on, I do not see the check engine light come on, can't pull any codes (won't link). when I turn the key to engage the starter, the indicators on LCD display go away. Also, the fuel gauge shows below E and I know there is over a half tank of gas, I am concerned maybe the computer went bad? need some ideas....
