There isn't a 'fuel control module'.

But there is a fuel pressure regulator

When you look up fuel 'module', you come back to the fuel pump.

One thing you might try is moving coil pack 4 to another cylinder and see if the code moves. After that do a plug swap and see if it moves. Do them separately not coil and plug together..

are you referring to the drain plug? if so, it is located on the passenger side bottom facing the front bumper. see attached diagram under radiator removal. http://www.kia-forums.com/attachments/kia-carnival-sedona/9678d1319024147-removing-radiator-kia-sedona-2005-remove-radiator.jpg

Hi, the Kia Sedona starter (and all other major parts) are the same from 2000 to 2005. Here is a link with your starter location and how to remove it:

In this pic you can see the starter's location (hidden behind the exhaust heat shield):

I hope this diagram helps.

Here's a link to the cylinder location.

By the camshaft reluctor wheel on the front of the engine by the belt side. Should be one bolt and a wire plug.

next to the 3rd cylinder

2005 kia sedona ecu is located on passenger floor under carpet. After you remove the carpet half way, there is a silver plate you have to remove with 10mm deep well socket. there are 4 connector plugs.
