Welcome to JustAnswer, my name is XXXXX XXXXX I'm here to help get your problem resolved. This vehicle does not have a distirbutor, it has 3 coils that power to cylinders each. Here is a firing order diagram so you can make sure you have correct order. Let me know if you have questions or if there is anything else I can do to help, thanks.
That last diagram shows where the spark plug wires should be connected. Here are 2 other diagrams I have, let me know if they help or if you run into questions. Thanks.
Here are pictures of crakshaft position sensor, camshaft position sensor which is 3 wires, and replacement instructions for timing belt. Let me know if you have questions, thanks.
Hell Regina, I would be glad to assist you. You can view the timing belt installation procedure with illustrations by clicking here
The most important step before you remove the belt is to make sure the crank and cams are aligned to their timing marks. You may have to turn the crankshaft twice for all marks to align, then you can follow the procedure. If you need help or clarification on any step let me know.
Also below is a better illustration of the cam timing marks.
These are like the coils, in that there is no definitive lifespan. With that said my personal observation and experience has been that they usually last anywhere from 100-150,000 miles.
With that said KIA comes with high quality sensors and when you decide to replace those I would suggest either ones from a KIA dealer or from OEM suppliers such as Auto 7 and Standard motor products. They are built to industry standards and will be as high of quality as KIA factory parts. I would highly avoid using any sensors made by the company Airtex, they have a high failure rate and are inferior parts from my experience.
Since you seem to be an avid DIY'er I also wanted to share this link with you as a source of high quality and discounted parts.
