how bad is it to replace the fuel pressure regulator on a 2004 PI motor. mine is going bad and its getting to be a pain in the but. and where are they located, is it the silver piece next to the upper section of the intake tube??

thanks

You have a returnless fuel system so the regulator is in the tank next to the pump. It is electronicly controlled. How do you know the regulator is going bad? Are you sure its not the FPS?

Return style is on the fuel rail.

i have an 03 and mine went out a few weeks ago. according to Ford, we dont have a a fuel pressure regulator, we have a fuel pressure sensor. its located on the fuel rail, a little black box. it cost $40 and took about 10 minutes to replace it.

If I could get my stupid ford cd to work I could show you the rgulator in the tank. Most of the time it is the FPS (fuel pressure sensor) that why I said to make sure that wasn't messed up.

i assumed that its the fuel pressure regulator. ok, i guess the fuel pressure sensor is going bad. where on the fuel rail is it located.

Driver side. Black box with wires and a vacum line coming out of it.

well the reason is, i am having problems starting the car, it will not fire up quick. takes a little cracking over. runs like a champ tho once its started.

Your pump might be dying or you have a leak in the fuel system like injectors or something. If you start it and let it run for a min and turn it off then try to start it right away does it start right up.
