I have an 05 and just a week ago a had an issue starting it felt like batteries were weak, but they were fully charged. One morning it crank for a little bit and then it felt like batteries were almost dead and all of sudden it started. Next morning it crank but no start. After many attempts it finally started. It turn out to be the fan clutch. I did have the code for fan speed p0483. Replaced the clutch problem fixed. Hope this helps good luck
