This morning when I started my 2000 Sonata GLS V6, the engine started run several seconds while not sounding normal. The I tried to restart it and while it would turn over it would not start. I was in a hurry so I switched to my truck and ran a few errands. Upon return I tried again to start the Sonata. It cranked but didn't start. Going back to my "shade tree mechanic" days I will have to say that it sounded like an old carbureted car that was not getting the correct fuel mixture. I tried cranking it again but this time let it crank for a longer period. It finally started and run OK. I turned it off and restarted it several times. It now starts and runs OK and the Service Engine light does NOT come on. WHAT HAPPENED??. Could the computer have gotten confused and ordered the wrong fuel mixture to the injectors? Old_Timer
