Fuel Pressure Regulator - Removal & Installing

The fuel pressure regulator is a diaphragm-operated relief valve with fuel pump pressure on one side and regulator spring pressure and intake manifold vacuum on the other side. The regulator's function is to maintain a constant fuel pressure across the injectors at all times. The pressure regulator compensates for engine load by increasing fuel pressure as engine vacuum drops.

The fuel pressure regulator is serviced as a separate component. When servicing the pressure regulator, make sure that the O-ring back-up, large O-ring, filter screen and small O-ring are properly positioned on the pressure regulator.

REMOVAL & INSTALLATION
The need to work as cleanly as possible cannot be over-emphasized. Even the smallest amount of dirt, if allowed into the fuel pressure regulator and/or the fuel rail, will find its way to the fuel injectors. The nozzle openings of the injectors are very small. Keep hands and tools clean. Clean the areas to be disconnected with a suitable solvent. Carefully cover open fittings and connections to keep out foreign material. Dirt in the injectors almost guarantees a clogged fuel injector and engine performance problems.
3.1L and 3.4L (VIN E) Engines

  1. Disconnect the negative battery cable.
  2. Relieve the fuel system pressure using the procedures found in this section.
  3. Remove the upper intake manifold assembly. Please see .
  4. Disconnect the vacuum line from the pressure regulator.
  5. Remove the regulator retaining screw and remove the retainer bracket. Using a clean shop cloth to catch fuel spillage, carefully pull the regulator from the fuel rail. Twist the regulator slightly while removing to ease removal. Discard the O-ring.

To install:
  1. Clean all parts well. DO NOT use shop compressed air to test or clean a fuel pressure regulator. Clean the fuel pressure regulator screen, if necessary. DO NOT immerse the fuel pressure regulator in a solvent bath or it will be damaged.
  2. If the filter screen has been contaminated, it should be removed and the pressure regulator replaced.
  3. Lubricate a new pressure regulator O-ring with clean engine oil and install on the regulator inlet.
  4. Install the fuel return pipe to the regulator.
  5. Install a new retainer and spacer bracket into the slot on the fuel rail and install the pressure regulator to the fuel rail. Tighten the fuel return line nut to 13 ft. lbs. (17 Nm).
  6. Connect the vacuum line to the pressure regulator and install the retainer screw. Tighten to 76 inch lbs. (8.5 Nm).
  7. Inspect and verify that the retainer and spacer bracket is engaged in the slots in the fuel rail. Grasp and pull on the regulator to ensure that it is properly seated.
  8. Install the upper intake manifold. Please see .
  9. Connect the negative battery cable.
  10. Inspect for leaks using the following procedure:
    • Turn the ignition switch to the ON position for 2 seconds.
    • Turn the ignition switch to the OFF position for 10 seconds.
    • Turn the ignition switch to the ON position again.
    • Inspect all areas for fuel leaks.

SOURCE: how to remove the door panel on a 2005 grand prix

Just an philips screw, you'll need to remove screws that are by the door handle, arm rest, under door and side of door and then gently pull back on the panel as there will also be retaining clips attached and you don't want to break them.

If needed, you can pull back the weather seal (can't reuse it, but it's not that important) and you will be able to access everything inside the door.

Hope helped with this (remember rated this).

SOURCE: 2005 pontiac grand prix, code p0641 came on. What

DTC P0641 The powertrain control module (PCM) provides a 5-volt reference to the following sensors:

The throttle position (TP) sensor 1
The accelerator pedal position (APP) sensor 2
The engine cooling fan speed sensor
The AC pressure sensor
The fuel tank pressure (FTP) sensor
The oil pressure sensor (OPS)
The PCM monitors voltage on the 5-volt reference circuit. If the voltage is higher or lower than required, DTC P0641 will set.

Conditions for Setting the DTC
The PCM detects a voltage that is higher or lower than required on the 5-volt reference circuit. The above condition is present for 1 second. Action Taken When the DTC Sets The control module illuminates the malfunction indicator lamp (MIL) when the diagnostic runs and fails. The control module records the operating conditions at the time the diagnostic fails. The control module stores this information in the Freeze Frame/Failure Records.
Conditions for Clearing the MIL/DTC The control module turns OFF the malfunction indicator lamp (MIL) after 3 consecutive ignition cycles that the diagnostic runs and does not fail. A current DTC, Last Test Failed, clears when the diagnostic runs and passes. A history DTC clears after 40 consecutive warm-up cycles, if no failures are reported by this or any other emission related diagnostic. Clear the MIL and the DTC with a scan tool.

Yes i can be dangerous, depending which issues mentioned above has triggered the code such as a faulty gas peddle position sensor. the code can also cause a reduced engine power to activate.

Thank you for using Fixya and best advice is to have the dealer address these issues. A tech 2 scanner would be needed to address the P0641 DTC code.

My 04 Grand prix gt will start then after sitting a while will not start i have to push the gas for it to stay started i just got this car and it only has 56k miles on it.


A fuel pressure test should be performed as I suspect the fuel pressure regulator is leaking fuel into the vacuum line causing the engine to flood on restart.
A drop in fuel pressure would confirm this.

What makes a car stop while driving but starts


Fuel pressure loss is the usual cause. Check your fuel pressure. This can be caused by a plugged fuel filter or a faulty fuel pump. The next thing to check is your fuel pressure regulator
