As far as I know the actual regulator is part of the pump.

The fuel pressure sensor is on the right side(looking at the engine from the front) of the fuel rail.

Has the mechanic checked the pressure at the rail?

He checked it at the filter but its easy to check it at the end of the rail right? Your saying its possible something could have made it through the filter and be stuck in the rail itself? and if its fine at the filter its
probably not the regulator correct?

Thank you

 

If it's the regulator, then it's really the pump. They're one and the same.

If you're getting a code for it, either the sensor is shot, or the pump is failing.

 

Fuel pressure regulator is in the fuel tank in the fuel pump carrier. I believe it is not sold as a separate unit.

 

Its plastic welded to the pump. Not replaceable. Have you replaced the fpr?

 

I'm not sure what you guys are talking about, sensor is on the fuel rail, pump is in the tank and the regulator is under the car near the fuel filter. Not sure how someone could measure the pressure near the tank unless they somehow tapped into the line. Easiest place to check is the nipple on the fuel rail or electronically with a scanner.

 

The actual regulator is part of the fuel pump.

This code, however, is normally associated with the FPS in these cars.

There are two schrader valves in the fuel system. One on the fuel rail, one at the filter.

 

there is also a Schrader valve next to the fuel filter near the FPS.

 

Perhaps controller is the better term instead of regulator. There is no mechanical fuel regulation in the R, just a sensor, controller and pump in the tank. The controller regulates fuel pressure by changing the duty cycle of the power circuit to the pump.

 

There is one in the pump. If you take the pump apart you will find it encased in the housing.

 

Whoa.....you ran out of gas? You could've overheated the pump. Not only does it need gas to not kill itself from sucking air, but it uses the gas as coolant.

 

Ok Guys I will give you the benefit of my $2000 fuel fix.

My car just died at the side of the road. I replaced the fuel pump, but it was the FPS. Everything was fine for a week then I had hesitation, went through 2 fuel pumps and a pressure sensor. In the end it was a bad fill from a gas station and the filter on the fuel pumps was being blocked. I drained the fuel tank as much as possible but had to remove the screen on the fuel pump to get the car working again. 2 fill later and all is going fine.

There are 2 fuel pumps, 1 pumps fuel to the driver side of the tank to balance the fuel in the tank.

Check the screen on the fuel pump, it sounds that its blocked, what happens is that it will run at low rpm but when you want to accelerate the fuel pump is at maximum output and you lose pressure and the wiplash starts
