Asked by May 22, 2012 at 02:47 PM about the 2006 Hyundai Sonata GLS

Question type: Maintenance & Repair

it turns over, but won't start up, if i turn it to where the gauges power up, it will start right up. I have used pure gas for over 4 years now, but put ethanol in it twice before this started happening. any ideas?

Ethanol is always bad. Switch to non-ethanol and see if issues go away. You can also try some SeaFoam in the gas to clear up residue from ethanol.

well i switched back to no ethanol and had no problems for a few days, and then last night it hesitated to start again. I guess i should have put that part in my question.. I'm going in to have the fuel filter replaced and possibly new spark plugs. I just wonder if the starter is going out?

Does it turn over at normal rpm the times it does start?

........run some fuel system cleaner such as SeaFoam this will help get rid of the residue from the ethanol.
