The above statement is GREAT!!! The wheel-well piece folds down across the area you need to be in. There are 2 screws to undo this part. Push it back and there is a cap that unscrews which holds the wires and socket he is talking about. Unscrew the cap, unscrew the wire and housing. The bulb comes out. You pull the wire harness off and install the new bulb. It has a triangular push-in and it has to go just right so take note of how it comes out. Also, being a halogen light bulb, do not touch the bulb with your hands - the oils will make it explode.

Remove the plastic cover that goes over the engine (the one with the Hyundai logo).
At this point, you will see the cables that goe to each fo the spark plugs.
Noting their position, remove them.
The spark plugs are ready to be removed, turn counterclockwise and replace with manufacturer recomended ones.

Hi,

Please follow the steps to change the fuel filter. You would need to remove the left rear seat (four 14mm bolts). I think you'll need to finish cutting through the tabs on the carpet to be able to lift up the carpet. Then remove the access cover. You can then remove the fuel pump from the top of the tank.

We went through this with ours recently. Hyundai diagnosed it as a bad crank shaft position sensor. We replaced it and we're up and running again. Not sure why the damp weather affected it but it did.
