You will need to replace the fuel pump and filter, The fuel pump is what makes the pressure.
It is incorporated into the fuel pump on that year onwards so no need to replace.
it is mounted on the drivers (left)strut tower under master cylinder and air filter box
By taking it to a professional for repair. This is not a DIY repair.By taking it to a professional for repair. This is not a DIY repair.
The fuel filter is located under the car behind the fuel tank on the right hand side It has 1 10mm bolt holding it on and "press" release clips for the lines
i don't have an 05 (mine is an 03) but the fuel filter should still be in the same place. that'd be on the drivers side, inside of the frame rail, forward of the gas tank. its a little silver canister, about 4 inches long and about 2.5" in diameter. actually, i have since found out that 03 was the last yr that they placed the fuel filter in the above location. starting from 04 models the fuel filter became part of the fuel pump...inside the gas tank...sorry.
The fuel filter is non-replaceable, and integrated with the fuel pump module which is inside the fuel tank. To replace the fuel filter, one must replace the entire fuel pump module, which requires either the removal of the fuel tank, or the removal of the truck box. Six of one, a half dozen of the other, as far as which method is easier.
In the 03 its to the right of the stering wheel behind the little flip box, but mine is still messed up had no fuse problems. No idea whaat to try next
Check under the car in the back by the gas tank - that's where it is on my '99.
You need check the transmission module first(very popular problem with 01-03 elantras), connectors(outside on the transmision) ,scan your computer to get some codes. po713 po760 po745
