It could be many things, unfortunately and without experiencing the problem first hand or being able to do some basic diagnostic tests its hard to say. Kia as a car manufacturer put a lot of great technical information and work shop manuals on line for free for Kia owners. www.kiatechinfo.com
Kia Vehicle no start. All electrical works but when you turn the key over nothing. Battery, starter, alternator, fuses... everything is good! Can jump starter to battery, and the car will start. THIS IS WHY: the "SAFETY NEUTRAL SWITCH" is located just under the battery- right beside it. The safety neutral switch had battery acid on it, which caused corrosion and created a pin hole in it. It wasn't very much damage, but enough to mess things up!! You can replace it. I personally, put a push start button in, bypassed the safety neutral switch, and no more "no start" issues! I did the push start button because it was cheaper than the safety neutral switch. I ordered a pretty one in too, so it looks factory. :) I hope this helps with all the different Kia No Start issues. (I have an 05 Kia Spectra)
Thanks!!!
