You need to follow logical diagnostic procedures when the engine stops running to figure out what is going on. A proper wiring diagram, a good volt/ohm meter is the least you will need, an oscilloscope and scan tool may be needed to get to the root of the problem. 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

no, not likely. you need to check for spark, fuel delivery and compression. you all of these for the motor to run. take it to a shop for a diag and a bid.
