It's remarkably easy to empty the trunk, remove the bottom pad, flop down both upper rear seats, pry the plastic sender cover off, disconnect the 2 electrical plugs, unbolt the pressure line and remove the return hose. Then remove the fuel sender assembly and that is where "easy" stops. The fuel temperature sender (part number : 31435-38300) clips to the bottom of the sender but when you go to remove the 7 mm nuts that attach it electrically to the sender, they don't loosen up. I wound up digging the molded rubber from the outside of the sending unit, drilling the studs out, replacing the outside wire connectors and installing bolts and nuts to connect the sensor to the outside wiring through the insulated connector parts and then sealing everything with silicone. Instead, just replace the sender assembly (not much more expensive and it comes with the temperature sensor) and swap over the pump.
I've never heard of a FUEL temp. sensor, are you SURE?

Fuel filters are not checked but just replaced.
This must be fuel injected. Trace back from the fuel rail toward the gas tank. You are looking for a small can sized object in the fuel line. Most likely this is about the middle of the drivers door up next to the inside frame rail.
A couple more things to check.
You can loosen the fuel connection on the frame rail and crank the engine, there should be fuel everywhere.
Yes, it's not the filter
No it's a blockage and most likely the fuel pump
Fuel pump is on top of the tank about the middle.
If you have fuel, then check the fuel injection regulator, on the front of the fuel rail for correct operation or just replace, especially if you have some miles on the car.
I've never seen a fuel filter complete plug the fuel system unless car has been especially abused.
You should also be able to hear the fuel pump running by just turning the key on.

Doug

i have the same problem with my 04 santa fe PO183 at first and now PO335 come up. and now it wont start, did anyone find the problem?
Hello
The
Engine and Automatic Transmission (not applicable to manual
transmissions) in this vehicles drive train are fully electronically
controlled by a computer called the PCM and TCM (Power Train Control
Module, Transmission Control Module). When a problem like this or
other drive-ability related problems occurs the computer stores a
record of the problem (there are of course some exceptions to this,
like the fuel pump, engine coolant temperature sensor and MAF sensor
for instance) in the form of a fault code in its memory, to read
these fault codes you must have the systems memory scanned with a
special tool. Once the fault code(s) are read you then must perform
the appropriate diagnostic testing to find and resolve the problem(s)
DO NOT REPLACE ANY PARTS UNTIL A TRAINED TECHNICAIN HAS DIAGNOSED
THE PROBLEM TO AVOID SPENDING YOUR HARD EARNED MONEY ON PARTS THAT
MAY NOT CORRECT THE PROBLEM. Also always check fuel pressure for
correct spec for your make and engine type.
