Question edited for clarity.
Question moved to sub category.

P0304 is only a misfire error to cylinder 4.

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..

I would employ a mechanic that knows what to do.
Under the rocker cover. You will need a gasket set.

Newer cars I have seen usually have the fuel filter in the tank. Vehicles with inline filter are usually located around the fuel tank or in the fuel line running from the tank to the engine. Did not find 2011 but other models I found have access to fuel pump and filter under rear seat.

Hi,
Here is the location of the "Knock Sensor" you requested, I hope it helps you. It is Number 17. for future reference here is the list of the others
1 = Camshaft position sensor (CMP)
2 = Crankshaft position sensor (CKP)
3 = Engine Control relay (EC) -engine bay fusebox/relay plate 1
4 = Engine Coolant temperature sensor (ECT)
5 = Exhaust gas recirculation valve actuator (EGR)
6 = Fuel Filter
7 = Fuel Filter Heater - in fuel filter housing
8 = Fuel Flow control valve - on high pressure fuel pump
9 = Fuel Rail pressure sensor(FRP)
10 = Fuel Temperature sensor - on high pressure fuel pump
11 = Glow Plugs
12 = Glow Plug Relay 1 - engine bay fuse box/relay plate 2
13 = Glow Plug relay 2 - engine bay fuse box/relay plate 2
14 = High Pressure fuel pump
15 = Injectors
16 = Intake air temperature sensor (IAT) - in MAF sensor
17 = Knock Sensor (KS)
18 = Mass Air Flow sensor (MAF)

the fuel temp sensor is located on the fuel pump inside the gas tank. under the left second row seat there is a carpet flap once you pull that up you'll see a black plate with 4 screws. remove the screws to gain access to the fuel pump. you'll need to disconnect the fuel line with a dealer only special disconnect tool. then you can remove the screws that hold the fuel pump to the tank. and pull out the fuel pump to gain access to the temp sensor.

I'm pretty sure your referring to the fuel regulator

i have tried a search and i cannot find where the 02 sedona offered a diesel option motor, i found only one available motor and that was a 3.5 sfi , well that pump is in the tank. Did you try and put diesel fuel in this vehicle? as it wont run on diesel.and its possible it fried the pump. but you will have to drain tank and flush fuel lines if this is the case.

start of at the gas tank look under neath there are some black lines running towards the engine follow it to a small gold color that ataches to the line you are following that is the filter the pump is in the gas tank you need to drop the straps at the tank to bring it down

The fuel filter is located in the fuel tank, pump removal is required to replace. There is an inspection cover behind the front seats on the floor to gain access to the pump. stupid idea. but whats not stupid about kia.
