my Malibu 1998 was working fine till i changed the tires on it, i jacked the back and changed the tires then i did the same infront ,when i tried to start my car it wouldn't start! I don't get it anyone have an idea what could of happened? I tried a few times to start it and the motor doesn't turn...when i checked in the oil it smelled like fuel so i did an oil and filter change and it still won't start. It had some trouble starting sometimes but wasn't a huge deal...at first i thought that it could of been the theft system but its been 2 days would it of come off by then?
