I need help quick, my 94 geo metro is driving me crazy. In the morning she won,t start, in the afternoon she,ll fire right up. Had new fuel pump and filter installed, took it to the mechanic and had a diognastic test done all he could find from that was oxygen senser was going bad but was told that would not be the problem for no start. T he mechanic had the car for a week and each time he he tried to start it she fired right up for him, was told to take car home and the next time it acted up to bring it back, well guess what I took car home and the very next morning she would turn over but wouldn,t start. can anyone help ME! by the way it is a 3 cylinder
