check both of your fuse panels for a blown fuse. there's 4-5 that control the fuel pump, engine sensors, fuel injectors and such. one of those may be blown and not letting the rest of the system function. one panel is located under hood, and one is under the dash on drivers side. when you take the covers off they have the fuses numbered and tell what they control.

Assuming the correct fuse is being used, there is a short somewhere in the wiring leading to the ECU or in the ECU itself. If no modification has been done to the wiring (such as aftermarket radio or alarm), the ECU may be bad. A dealership may be able to test the ECU if you remove it, but will probably charge for the service. You may be able to find a cheap ECU at a junkyard for the same cost. You can use an ammeter to check power consumption at the fuse slot. If there is more than rated amperage consumption with the key on, engine off and ECU in, there is a short. Remove the ECU and recheck. If there is more than about a hundred milliamps with the ECU out, the short is in wiring. If not, the short is in the ECU. If there has been modification to the wiring, check it for shorts or exposed wires, and remove the mods if possible. You may also be able to get a pinout for the ECU from Kia and check for incorrect shorts to ground on each pin using a self-powered continuity tester.
