Where do I find the fuel pressure regulator and how to change it on a 2001 hyundai xg300

to answer that would need need the 3 ltr V6 motor repair manual and from the fuel section
the pressure number
without a pressure gauge
if the fuel pump is pumping fuel to the injector rail
test if fuel pressure regulator is not full of fuel and the vacuume pot is holding

Any codes set? Check fuel pressure? Check EGR valve?

Well you have fuel injectors instead of a carb.
I would check fuel pressure first. And if the check engine light is on, check the engine computer for trouble codes too.

hi martin i am shannon . you will first need to determan if the problem is fuel or spark related . for fuel just add 1 oz of gas into the intake through the throttle. you will need to remove the big black hose at the throttle . just pour the fuel in. if it starts right up then you have a fuel issue most likely a bad fuel pressure regulator. too test the spark i would get a spark tester . connect it to one of the plug or coil wires. set it to 25.0000 volts then have some one turn the engine over while you which for spark. if you get no spark you may have a bad crank angle sensor. hear is a spark tester i use . this one is at Autozone.

check the fuel filter to see if is plugged up, it may not be getting enough fuel to go down the road.

Visit http://www.obd-codes.com/trouble_codes/ and
http://hyundai.wikia.com/wiki/OBD-II_Error_Codes
for the codes you have.

So the 171 and 174 indicate lean fuel/air, the 1191 and 1193 indicate the car is in limp home mode. And 1632 is a traction control issue.

The lean mixture might be as simple as a plugged fuel filter, or as complex as trouble with the injectors, the throttle position sensor, fuel pressure regulator, or fuel pump. How long since you replaced the fuel filter? If it has been close to or beyond the recommended interval this is a cheap ($20 for the part) and fairly easy thing to try.

The lean fuel/air could be the cause of the limp home mode.

The 1632 code is a traction control system malfunction. Could be an intermittent issue or occurred because the engine is operating erratically. With this code the car should still run fine, but the TCS won't work properly.

Check the fuel filter to see if it is restricted,and if it is not have the fuel pump pressure checked,this is the most likely cause of your problem.

I THINK THERE IS A STRING IN THE TRUNK ON WICHEVER SIDE THE FUEL DOOR IS AT
