Hi there...i don't have room to post the complete diagrams here, but i can walk you through the steps. It's a little harder for a do it yourselfer than most cars, because the intake manifoild has to come off---one of the reasons a shop charges so much too...and a proper set of tools is very helpful. Your manual will have pictures, to help you identify the parts i describe here...ok u ready?

Take off the plastic engine cover and set aside. Don't lose the the little acorn nuts.

1. Remove the air intake hose connected to the throttle body.


2.

Remove the accelerator and cruise control cables.

3.

Remove the engine coolant hose and throttle body.

4.

Remove the P.C.V. hose and brake booster vacuum hoses.

5.

Disconnect the vacuum hose connections.

6. Remove the surge tank stay.

7.

Bleed off the pressure in the fuel pipe line to prevent the fuel from spilling & squirting you in the eye.

8.

Disconnect the connector from high pressure hose.

9. Remove the surge tank and gasket...be careful with gasket, you can reuse it.

11. Remove the delivery pipe with the fuel injector and the pressure regulator....
When the delivery pipe is removed, be careful not to drop an injector.

12.

Disconnect the wiring harness of the coolant sensor assembly.

13.

Remove the surge tank.

Ignition coils and ignition wires:
disconnect ignition coil harness connectors

disconnect ignition wires from ignition coils

remove hold down bolts from ignition coils

while gently twisting pull up and remove ignition coils

while gently twisting pull up and remove ignition wires

remove spark plugs (always check gap on new plugs, even if they say they are "pre-gapped" )

Install in reverse order, don't over torque anything and keep your work area clean. Now would be a good time for wire replacement too---depending on the mileage on your Kia

Do a good visual inspection of hoses, clamps, wires & pulleys while you have it "opened up" ---Good luck, thanks for using fixya and i hope you get many more trouble free miles out of your Sorento. =)

SOURCE: Can't find where the spark plugs are located

The 2003 Kia Sorento with 3.5L V6 has the spark plugs located under black plastic covers in the center channel of each cylinder head. Several brackets, cables, and hoses must be moved out of the way to access them. The manufold air intake tube needs to be removed on the right bank.
The left cylinder bank has coil-on-plug assemblies while the right bank has more conventional spark plug caps with sealing assemblies to keep dirt/moisture out of the spark plug wells. The coil-packs are held with two 10mm bolts each and are difficult to get to. Use universal-joint sockets and an extension.

Takes about  2.5 hours to R/R spark plugs. The average do it yourself'er will take longer (usually). All electrical plugs are color-coded and/or indexed so it's pretty difficult to screw it up. The cruise control actuator cable is in the way on the left bank. Twisting the cable elbow upright releases it from the actuator allowing it to be bent sideways to gain clearance. 

Good luck and hope this helps.

Be careful there.. If you remove the Throttle Position Sensor TPS or the throttle Cable, the engine light will come on because there is a certain setting that needs to be done to ensure accurate emission control.

How to tell if a fuse in 2003 Kia Sorento is good

None of those would be fixed by replacing the battery. Or did you replace the battery and then all of those stopped working?

You can tell of blade fuses are blown if you full them and hold them up to the light. That is a whole lot of stuff not working. I would say you need a good auto-electrician.
