I have a 2003 Kia Rio, sometime it wont start and other times it will, we took it to the garage and they could not find anything wrong with it and of course it started the whole time it was here, we took it home and now it wont start, sometimes it wont start for days then all of a sudden it will start. It has a new battery, new starter......what is wrong with this car??

Yes they rend to get binded inside.you have switch and then u have another electric part that makes contact

Check altanator

get the service and repair manual from the given link and i am sure you will fix the problem easily yourself http://toolsnyou.com/

Check Alternator Voltage regulator if it fails it can send up to 18volts to the battery and make sure your battery is not too old usually most batterys will fail after around 2-3years causing the alternator to work harder . Also check your fuses someone may have put a wrong fuse somewhere. Don't buy a used alternator. Good luck.Student Mechanic LWIT Kirkland

Hi Grey:

Hope this helps; also keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using Fixya, and have a nice day.

My 01 did the same thing, it was the main relay in the fuse box. Try taking the headlight relay and switching it with the main. If that fixes it might want to keep a few on hand, my most recent relay went out was the c/fan which in turn overheated the engine and the fan melted off the motor.

they should have given you a possible problem print out , realy need to know what p 3606 is
any way it could be you idle air controle valve ,clean it , and or replace it.

Hi
I cant tell you why but I do have a solution for you to try, I had a similar fault on a fiat punto last year, I disconnected the battery for an hour and then put it back and the car started, Im still puzzled by this but It may work for you, worth ago, make sure you have your radio code before removing the battery

Hope this helps
Regards
Dan

We had the same problem.
I took out the bolts outside, then crawled into the back area of the car, and took a screw driver, and slid it along the inner hatch catch, and found the safety latch and released the hatch. Then I took the inside off, and disconnected the handle device from the inside. It was rusted, and broken. I went to Kia, and bought a new one and reinstalled, after greasing the new one up. Took me a while, but they wanted 280.00 in labor, so it was well worth it.
Just be patient and go slow. A good metric socket set will be the best thing, with a regular and phillips screw driver.
Good luck
David
