After reading several articles, I am trying to determine why it takes several attempts to fire engine. Every morning, my car will not start on the first attempt. I have to take the key out of the ignition switch and wait then try again. Engine usually starts on 2nd attempt; however, there is a lot of exhaust smoke (white), but my car starts and runs smoothly. My display reads electronic errors...oh btw, if I let the fuel gauge fall below half, my car will not start??? Any suggestions...jmb
