2004 Kia Optima 6 cyl Front Wheel Drive Automatic 44000. miles

My car will start but once I stepped on the gas it will not run at all. I have plenty of gas in my car so I dont know what the problem is Help!

SOUNDS LIKE THE THROTTLE POSITION SENSOR ! BUT USE YOUR WARRANTY! TAKE IT TO YOUR DEALER&GET THEM BY THE THROAT IF NESSARY,& MAKE THEM FIX THE PROBLEM. YOU HAVE A 100000 MI.WARRANTY ON THE POWERTRAIN EVEN IF YOU BOUGHT IT USED ! KEEP IN TOUCH!

I agree that you should take back to a dealer for warranty. My Kia Optima had similar symproms at 101,000 mi. and it turned out the electric fuel pump harness had melted creating an open in the circuit. Sometimes it would run and others not. Also, just for fun, check the National Highway Transportation Safety Administration website . Ther are two other situations of burned up harnesses (inside the fuel tank), but no recall
