When you replaced the starter, did you disconnect the battery? If you did, it is the security system and engine immobilizer that is stopping the car from starting. It needs resetting. Not so easy in a Kia!

The Throttle Position Sensor is nothing to do with the Starter.

The item with the wires you refer to, is normally called the coil pack, but yours has the coil on top of the spark plugs.

So what it has is a modern type distributor that is 'distributorLESS'.

DTC Code P2159 DTC Code: P2159 Description: Vehicle Speed Sensor ?B? Range / Performance Probable Causes:

1. Sensor or solenoid faulty
2. Connector terminal contact is damaged or corroded
3. Wire harness - Check harness for correct voltage, open, short to ground or short to voltage
4. Update control unit software - Check for the latest control unit update
5. Powertrain or Engine Control Module faulty

try starting in nuetral when this happens the most probable cause is nuetral safety switch/multi-function switch on trans. common cause

What I can tell you, is to get the car out of the dealership

You don't go there for transmission work,you go to a
trans shop,unless money means nothing

Its likely you need a blower motor , its what draws power
while running , a mechanic with a multimeter and probe
can check it.

remove the positive terminal on the battery side for about a minute then reapply it this should reset it ......
