Do you have a diagram of the engine of the 2002 Kia Spectra because I need to replace the starter

Question edited a bit more clarity.
Question moved to model category.

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'.

i guessing its an automatic, if it is its the neutral switch not working and probably needs replacing, if it worked in second gear then the switch is not lined up correctly meaning it could be snapped inside https://www.autozone.com/batteries-starting-and-charging/neutral-safety-switch/kia/spectra/2002

If you just replaceD the engine in your 2005 Kia Spectra, was the replacement engine a good one? It sounds to me like it's a starter or starter solenoid issue! Try "hot-wiring" the starter solenoid, to see if the engine cranks. All security systems are "low level" in terms of current control. But a DIRECT connection from a good battery to the starter solenoid should engage it, which should complete the circuit from the battery to the starter motor.

if your local dealer cant replace it. Try a auto salvage yard. Hope this helps.

It is attached to the bell housing on the drivers side. The starter is located in the back of the engine, under the intake manifold.
