Check if there is spark at the spark plug cables, it's either the coil or the camshaft sensor.

Even though the fuel filter and pump are easy to replace, I would start with the IAC sensor first. It is easier to get to and is cheaper than the other two if you can find one at a wrecking yard (should be around $20). This sensor is the Idle Air Control sensor, and the computer decides how much throttle to give at idle from the readings of the sensor. If it is bad your car will idle poorly or not at all.
You can verify this two simple ways:
1. Disconnect the sensor completely and see if anything changes. If you get the same issue, then it's probably the sensor. If different then it could be fuel delivery.
2. With it all hooked up; try throttling the engine yourself at 1000-1200 rpm and see if it is smooth. If it is then it is probably the sensor. If not then could be the fuel delivery.
The sensor is under the silver and black, plastic KIA cover over the engine (4 small nuts to remove), and is center above the engine on the front side of the intake pipe. 
The part looks like this:
If it seems to still be fuel delivery, the filter is (facing the engine from the front of the car) down to the left and toward the back attached to the fender well (Just to the right of and below the battery)
SOURCE: 2000 kia sportage pump is working relays have been
there is a splice for fuel injectors at the front of the fuel rail conduit and electric tape will need to be removed to see if it is ok then clean up all engine grounds and ecm grounds on passenger side kick panel if this doesnt help check coils and crank sensor
SOURCE: need wiring diagram for 2001 kia sportage , need it for fuel pump
my 2003 kia sportage xse speedo stopped, rev counter still works. anyone got any idea
SOURCE: 2002 Kia Sportage will not start.
p0560 is system voltage problem. open or short between the battery positive and the ecm.CHECK ALL FUSES. dosnt matter what they are labeled under dash and under hood replace any that are bad and retry to start. no start then check voltage to ecm grounds to. i dont have a wireing diagram to give you but for a small fee or free the dealer can make you a copy.make sure all the wires that go to battery terminals are not corroded and are making good contact [verified with volt meter]. if after all checks ok then replace ecm. as a side note i havent had to change one ever.
Testimonial: "Thank you for the help. We will continue to check all fuses and wires."
Your problem may be one of the following:
First check or just replace the fuel filter. Usually located under the car in front of the rear axle, drivers side.
Next, the fuel pump may be worn out. Usually they just stop working (running).
Next, check the fuel pressure regulator. Usually located on the front fuel rail, drivers side.
Is the vacuum line attached? Not leaking or rotted?
Also, do you smell a strong fuel odor when it won't start? May be one or more stuck-open injectors, or the coil pack is bad.
Checking these in the order listed will more than likely fix your problem.
The clicking noise indicates the battery can no longer run the starter, which also means the fuel pump won't run either.
It could be a fuel issue. How old is the fuel filter? Can you hear the pump run for a few seconds when you turn the key on? Try turning the key to ON without trying to start engine three times waiting for the pump to stop running each time. Then try to start the engine. If it starts, Its a form of Vapor lock caused by the extreme heat we have had lately, and a weak fuel pump.
If none of this works, try a new fuel filter first. From there have someone check the fuel pressure regulator and then the pump. If you are in need of a new pump, take my word for it and spend the money to get one from a Dealer, and not from your favorite parts store. Most parts store parts are made in China and they are JUNK.
