someone said that it was the fuel pump1 another said that it might be the fuel filteror some thig under the car pertaing to the fuel might need cleaning out .
the car will not turn over when i turn the key it treis to start but will not! on 2003 Chevrolet Malibu
3 months ago that happened to me. I had to replace the fuel pump. Just today it happened again and it was a faulty anti-theft/key sensor. I have also replaced the ignition switch when I had that issue. It's becoming quite expensive to keep this car from blowing up!
a engine needs gas and spark,so lts one or the other,check the spark at the plug.if you have spark then go to fuel problem...
