SOURCE: Toyota V6 fuel pressure amount

The fuel pressure regulator is on the driver side fuel rail, close to the back of the engine. You need to pull the intake plenum off to access the pressure regulator.

The normal operating fuel pressure is 38 to 44 PSI

SOURCE: Tips on changing the fuel pressure regulator out

Not only will I give you tips, but step by step instructions :

Even though it is in open view, this is a really tight space, and small hands are good. - First you need to make a little extra room. Using a 13mm socket, back off the bolt holding the throttle valve so it is flush and not protuding towards the regulator. Pull the throttle swinger back and out of the way and jam it in place with a long screwdiver fed from the back. -Remove the PCV valve from the valve cover and connecting tube. -Remove the vacuum line from the regulator. To remove the bottom feed line, use a 15/16" open end or metric equivalant, turning clockwise when looking from the top. It will only move about 1/6 turn, then flip the wrench. When loose, pull the tube out as far as possible. -To remove the screw holding the regulator in place, you will need a T-27 star driver, a 1/4" hex wrench, and a 1/4" socket. There is no room to get a rachet in there, and do not try using an allen wrench or you will be so sorry. -Put the T-27 driver into the socket, and slide the wrench over the driver so it is on the hex part. -Put your contraption into the screw, using one hand to apply back pressure to hold it in place, and turning the wrench with the other. Once you get everything loose, you can kind of twist the regulator out. Installation is the reverse, but be sure to lube both seals with a little oil and a q-tip.
-Tighten the T-27 screw until it is about where it needs to be, then make sure the bottom feed tube is pushed in all the way. You'll probably need needlenose pliers and a magnet to get the feeder tube nut back up, and start it manually, making sure it is straight before you put the wrench to it.
-Tighten both snuggly, and put everything else back the way it was. Turn the key and drive away.
Please let me know how it goes.

You mention no check engine light, and all the work you've done leave one solution; Your catalytic converter is clogged.

When you replace you catalytic converter your issues will cease. This is a very common problem, and a simple fix.

I hope this information helps and I wish you luck with your repair.

Have a 2004 grand Android v6 replaced fuel pump Android fuel filter. The next thing must be the fuel pressure regulator were is it Android were do I check the pressure at Android were is the fuel rail...

the fuel test port is right behind the power steering pump. You will see a black plastic cap right behind one of the power steering lines. Remove the cap and you will see the schreader valve.

The fuel pressure regulator is on the drivers side of the engine next to the throttle body right where the throttle cable is attached. there will be a vacuum hose on the top of it a steel line coming out of the bottom and there will be a single bolt holding it to the fuel rail. Remove the vacuum hose from the top, start the engine, and see if fuel comes out. If it does than the regulator is leaking and needs to be replaced.

Fuel Pressure Problem on my 1996 Ford Explorer (4.0 V6)

Sounds like the fuel pressure regulator is going bad...this will cause the fuel pressure to be high and create a flooding condition. Which in turn will gas wash the motor and contaminate the O2 sensor with excessive fuel. Check fuel pressure with a gauge at the valve you are using to relieve pressure. You can find pressure specs on-line for that particular vechicle. If pressure is high...replace regulator, O2, change oil and reset computer by disconnecting battery for ten minutes...

How to replace a fuel pressure regulator

Is it the 3400 v6 or the 2.2l four cylinder? If it the v6 then what you have to do is first know where it is. It located on the end of your fuel rail on the driver side of the car. There will be a plastic hose coming off the top of the regulator, unplug it. You then have to undo your fuel line that runs into the bottom of the regulator. You have to use a wrench to get it off, not sure what size it is. Once you undo the fuel line the next step is to unbolt it from the fuel rail. There will be two screws that run in the side of the fuel pressure regulator that are facing the driver side of the car and are threaded in towards the passenger side of the car, just undo those two screws and the regulator should come off. Just repeat the process backwards to put it back on.
