Where is fuel pump relay on 2009 gmc acadia


Your vehicle has no fuel pump relay . Has a fuel pump flow control module .
Fuel Pump Flow Control Module (FPCM)
The fuel pump flow control module (FPCM) is a serviceable GMLAN module. The FPCM receives the desired fuel pressure message from the engine control module (ECM) and controls the fuel pump located within the fuel tank to achieve the desired fuel pressure. The FPCM sends a PWM signal to the fuel pump, and pump speed is changed by varying the duty cycle of this signal.
Plus it has two fuel pumps !
The high pressure fuel pump (9) is a mechanical one cylinder design driven by an eccentric on the exhaust camshaft (1) of bank 2. High pressure fuel is regulated by the fuel rail pressure (FRP) regulator, which is a part of the high pressure fuel pump. The FRP regulator is a magnetic actuator which controls the inlet valve of the high pressure pump. The ECM provides battery voltage on the actuator high circuit and ground on the actuator low reference circuit. Both circuits are controlled by the ECM. When the ECM deactivates the FRP regulator, both circuits are disabled and the inlet valve is held open with spring pressure. When the ECM activates the FRP regulator, the low circuit driver connects the low reference circuit to ground and the high circuit driver pulse-width modulates (PWM) the high circuit. The ECM uses the camshaft and crankshaft position sensor inputs to synchronize the FRP regulator with the position of the eccentric on the camshaft. The ECM regulates fuel pressure by adjusting the portion of each pump stroke that provides fuel to the rail. The high pressure fuel pump also contains an integrated pressure relief valve.
Your best bet is have it towed to the dealer , you don't want to mess with the high pressure pump .

Where is location of fuel volume regulator


Fuel pressure regulator ! An it's location is inside the fuel tank .
The fuel pump (FP) module contains the fuel pump, fuel pressure regulator and the fuel sender assembly. The fuel pressure regulator is attached to the fuel pump in the fuel pump module located in the fuel tank. It regulates fuel pressure supplied to the fuel injectors. The fuel pressure regulator is a diaphragm-operated relief valve. Fuel pressure is established by a spring preload applied to the diaphragm. Excess fuel is bypassed through the regulator and returned to the fuel tank.

Not likely. It is also not likely that the regulator is in the fuel pump assembly. Some people mistake the check valve in the pump as a regulator. Also, some vehicles have a pump module which includes the fuel gauge sensor and that can be mistaken as the regulator by some DIYers. The caravan uses a return-loop fuel system. This means that the pump is cycling fuel from the tank to the fuel rail on one line and the fuel that is not needed at the injectors flows back through another line to the fuel tank. This is done to prevent the pump from building up too much pressure and allows the fuel flowing through the pump to keep it cool. Because of the looping system, there needs to be a flow restrictor (aka regulator) at the fuel rail to provide a constant pressure source for the injectors. The regulator is normally at the end of the rail and will have a vacuum line attached. Pull the vacuum line, place a rag at the vacuum port, and crank the engine. There should be no fuel coming out the port. If any fuel comes out of the vacuum port, the regulator is faulty. The regulator could still be faulty even if there is no fuel from the port, but fuel leakage is an easy way to be sure. If the regulator is not providing proper restriction to maintain pressure, then the fuel simply flows in a circular loop from and back to the fuel tank without enough pressure to allow the injector to do their thing,

How would I replace my fuel Filter


The fuel filter is an integral component of the fuel pressure regulator, which is mounted on top of the fuel pump module, located in the fuel tank. When the fuel filter/regulator assembly requires service, the fuel tank must be removed from the vehicle, however, the fuel pump module does not need to be removed.
  1. Disconnect the battery ground cable.
  2. You dont have to relieve your fuel systems pressure because your jeep has an automatic bleeder.
  3. Remove the fuel tank assembly.
  4. Clean the area around the fuel filter/regulator.

Fig. Fig. 6: Replace the old fuel filter/pressure regulator mounting gasket

  1. Disengage the retaining clamp from the top of the filter/regulator assembly. Discard the retaining clamp.
  2. Using 2 small prying tools, pry the filter/regulator assembly out from the top of the fuel pump module. The filter/regulator assembly will unsnap from the fuel pump module.
  3. Remove and discard the mounting gasket below the filter/regulator.
  4. Before discarding the fuel filter/pressure regulator assembly, inspect the assembly to verify that the O-rings are intact. If the smallest of the 2 O-rings cannot be found on the bottom of the filter/regulator, it may be necessary to remove it from the fuel inlet passage in the fuel pump module.

To install:

Fig. Fig. 7: Check the condition of the fuel filter/pressure regulator O-rings

  1. Clean the recessed area in the pump module where the filter/regulator assembly is to be installed.
  2. Check the replacement filter/regulator assembly to make sure that the new O-rings are already installed on the assembly.
  3. Apply a small amount of clean engine oil to the O-rings.
  4. Install a new gasket on top of the fuel pump module.
  5. Press the new fuel filter/pressure regulator assembly into the top of the fuel pump module until it snaps into position (a positive click must be heard or felt).
  6. The arrow on top of the fuel pump module should be pointed towards the front of the vehicle (12 O&rsquoclock position).
  7. Turn the filter/regulator assembly until the supply tube (fitting) is pointed to the 11 O&rsquoclock position.
  8. Install new retainer clamp (the clamp snaps over the top of the filter/regulator and locks to the flanges on the pump module).
  9. Install the fuel tank assembly.
  10. Connect the negative battery cable.

Pressure regulator could be a factor, but may be part of the fuel pump assembly. Fuel filter could be a factor, but again, with some Chrysler vehicles the filter, regulator and such are all part of the fuel pump assembly.

Where is the fuel pump located in a 2005 Neon and how do you replace it?


Locate the Fuel Filter and Fuel Pump

  • Raise the Neon's rear end on jack stands. Remove the panel inside the trunk covering the fuel pump assembly. The fuel filter should be on top of this. On most Dodge Neons the filter is usually directly attached to the fuel pump. In that case, those two parts should not be separated and should be replaced together.Its a silver dome about 2.5 inchs round with a single plastic hose coming off it.



  • REMOVAL :-------
    WARNING: THE FUEL SYSTEM IS UNDER A CONSTANT PRESSURE, EVEN WITH ENGINE OFF. BEFORE SERVICING THE FUEL FILTER/FUEL PRESSURE REGULATOR, THE FUEL SYSTEM PRESSURE MUST BE RELEASED.

    1. Refer to Fuel System Pressure Release in the Fuel Delivery System section of this group. The fuel filter/fuel pressure regulator is located on the top of fuel pump module. Fuel pump module removal is not necessary.
    2. Raise vehicle on hoist.
    3. Disconnect fuel supply line at the Filter/Regulator nipple.
    4. Depress locking spring tab on side of Fuel/Regulator and rotate 90 ° counter-clockwise and pull out. NOTE:Make sure that the upper and lower O-rings are on the Filter/Regulator assembly.

    INSTALLATION
    Lightly lubricate the O-rings with engine oil.

    1. Insert Filter/Regulator into the opening in the fuel pump module, align the two hold down tabs with the flange.
      1. While applying downward pressure, rotate the Filter/Regulator clockwise until the the spring tab engages the locating slot.
      2. Connect the fuel line to the Filter/Regulator.
      3. Lower vehicle from hoist.----------------
