Fuel Pressure Regulator 2002 Santa Fe

After a lot of research, I am very certain that the problem with my Santa fe's hard starting and fuel smell (and possibly the bad fuel mileage) is the fuel pressure regulator. It looks like a pretty easy fix on most vehicles. I can not find a diagram of the Santa Fe. Does anyone have any tips for a financially strapped girl who has started doing her own mechanical work. Either where I can find a diagram or some more advice before I dig in? I have been able to do everything I have done on my vehicles so far but usually have some kind of guide for dummies. Any help would be appreciated!
My vehicle is a 2002 hyundai santa fe, v6 2.7 liter, 99000 miles, just purchased. Everything else is running great.

My santa fe start and run 3 sec after stall but if i put it at 1500 rpm it always run. when stallihng its like i put the ignition off no esitation and i crank and run all the time but stall


suspect the fuel filter. if you replaced the fuel filter & still stall, use fuel pressure gauge to check the fuel system. (could be bad fuel pressure regulator or fuel pump.)

Hard to start on 2002 hyundai santa fe? everytime i push gas once then start work and run good can u tell me what is wrong?


yeah, it should start without pushing the gas pedal. Sounds then, like too little gas, or too much air. I would start with a fuel pressure test to see if pressure is up to specs. Also check for any vacuum lines disconnected or bad. Might want to see if engine has any trouble codes. Some parts places (autozone) will check for codes for free. When was last time you changed your fuel filter? Might need replacing. Good luck.

Where is the in-line fuel filter on a 2002 Hyundai Santa Fe located.


I am not familiar with that model, but it dosen't sound like a fuel filter to me .
If it runs good after you get it started,the filter is probably ok,i don't know where it is located on that model,but it sounds like you have already found the problem (low fuel pressure) check for leaks,make sure the lines are on the right places on tank .Whatever is causing low fuel pressure is probably the solution.
hope this helps!

Where fuel pressure regulator located on a 2004 Hyundai Santa Fe. I have checked the fuel pump, and blown out the lines, but there still is no pressure at the fuel rail.


Are you sure the fuelpump is good,even a bad regulator you should still have fuel preasure,the regulator if its not part of the pump should be on the fuel rail,

My 2002 Santa Fe starts real hard lately. I was told the battery was failing, so I replaced it. It started real easy the first time, but after that I have to crank it for 10-15 seconds before it barely...


if the fuel filter was plugged you would have no power but the engine would start ok, chances are you have a defective fuel pump check valve, this causes the fuel to leak back into the tank and when u start it the engine is very lean until the air bleeds out of the lines, any wshop can verify this quickly by doing a pressure leak down test on the fuel pump.

Hi, I have a 2003 santa fe that wont start. Someone came with a scanner and told me that the computer was sending 26.8 of fuel pressure, and should be around 3. What should I do?


check for a plugged filter first the check the fuel pressure regulator see if too much fuel is escaping to maintain proper pressure check specs for true pressure first alanwrench

Loss of power/bad smell


One of the things that it could be is that the catalytic converter has rotted away internally. The rust and particle will then clog your muffler causing loss of power. I ran into this at about 140,000 miles on mine. That could be the source of your problem
