The fuel pump in the sportage turns on for a second or two when the inginition is first turned on to pressurize the fuel system but shuts down until the engine is started. If you have over 60,000 miles on the timing belt it is a likely suspect, they break without warning and the symptom usually is that the car will just stop running and will not start.
