I purchased a used, one-owner 2004 KIA Sorento with a no-start problem. I thought it would be something like installing a new fuel pump or relay. It has been a disaster of epic proportions! I have spent almost $3,000 on repairs to no avail. I even took it to my local KIA dealership who after a week of pathetic excuses was unable to figure it out. I replaced the fuel pump 2 times, I also replaced the fuel pump relay, both sensors at the engine block plus the timing belt. The car runs for a week or two then refuses to run; it will crank but will not start or run. Eventually, it starts and runs again. This seems to be an intermittent issue. Buying this KIA is the stupidest car purchase I have ever made (and I used to own a Ford Pinto). I'd give the damned thing away but, I have never made an enemy in my life. Although, giving this turd on 4 wheels to a friend would quickly gain me an enemy. I'm our of luck, money and patience. Does anyone have any useful advice?
