What does it mean when no fuel comes out of the fuel pressure regulator but there is fuel in the fuel rail?


fit a fuel pressure gauge and flow meter in the fuel line if the pressure is low replace the pump,if the flow is low replace the fuel filter, if the fuel pressure is high replace the fuel rail pressure regulator.

I'm trying to change the fuel pressure regulater valve on my 2004cts cadilac.I checked the fuel rail not there. Someone told me It is on top the gas tank.Please help me locate it.


What engine does yours have ? 3.6 L engine the regulator is inside the fuel tank !
2.6 an 3.2L is on the fuel rail !
5.7L inside fuel tank !
The fuel pressure regulator attaches to the fuel return pipe on the fuel sender assembly. The fuel pressure regulator is a diaphragm-operated relief valve. A software bias compensates the injector on-time because the fuel pressure regulator is not referenced to manifold vacuum. The injector pulse width varies with the signal from the mass air flow (MAF)/intake air temperature (IAT) sensor.
With the engine running at idle, the system fuel pressure at the pressure test connection should be between 380-410 kPa (55-60 psi). With the system pressurized and the pump OFF the pressure should stabilize and hold. If the pressure regulator supplies a fuel pressure which is too low or too high, a driveability condition will result.
You would have to change The modular fuel pump sender assembly !
Now what makes you think you need to have it changed ?

Could be a fuel pressure regulator or lost signal from crank sensor that gives inaccurate data.
The crank sensor is responsible for sending data to increase fuel pressure as a function of increased RPM. If the RPM reads low, then fuel pressure will be low.
Check fuel pressure.
Thinking that air pressure is affecting pressure regulator and compensating for a weak regulator diaphragm.
Would be interested in final fix of your problem.

Crank tolong before it start


First check your fuel pressure regulator by pulling the vacuum line off and check for fuel there should not be any.Then start the car and with a pressure gauge hooked up to fuel rail pull the vacuum line off the pressure should rise 5-10 psi if it does'nt replace regulator.Next check the fuel pressure it should be 41-47 with key on and engine off if not within specs replace fuel pump.

Removal & Installation of fuel Regulators on
4.8L, 5.3L & 6.0L Engine To Remove:
CAUTION
Three styles of fuel pressure regulators and fuel rails will be used in this model year. Each regulator has a different "footprint" that consequently changes the size of the receiving port in the fuel rail. The regulator retaining clips are specific to each rail-regulator design and cannot be interchanged.

How to change a fuel pressure regulator in a 1997 pontiac grand prix


GM Century/Lumina/Grand Prix/Intrigue 1997-2000
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.

Hope this help (remember rated this).

Fuel pressure low at pressure monitor


HI. There are some areas that will need to be checked for faults, in this case. Check the following:

1. Fuel filter- If this device is clogged, or faulty, it will decrease the flow of fuel to the injector assembly. If the filter hasn't been changed recently, this will be a good place to start.

2. Fuel pump- This device may be weak, or grounded poorly. check the ground, and all wires the link the pump to the power source. replace any corroded contacts and connectors. wires,as well, if needed.

3. Fuel pressure regulator- The fuel pressure regulator is used to keep the fuel pressure in the fuel rail consistent and change the fuel pressure depending on the throttle position. The fuel rail is in a fuel loop between the fuel pump feed and return lines. Because the fuel delivery requirements change depending on the engine's throttle position and engine loads, the fuel injection system must be able to adapt to meet the fuel requirements of the engine's operating conditions during idle, acceleration and steady cruising.The fuel pressure regulator has a small vacuum line attached to it that allows the pressure regulator to change the fuel pressure in the fuel loop depending upon the intake manifold pressure which changes as the throttle position changes. When the throttle is opened, the manifold vacuum pressure drops off, causing the pressure regulator to increase the fuel pressure in the fuel loop, which increases the amount of fuel delivery at the injectors to provide for the additional fuel needed for the engine to operate properly.At idle, the manifold vacuum increases and the demands for the rate of fuel delivery are decreased so the pressure regulator decreases the fuel pressure in the fuel loop.

1. Look for visible evidence of fuel leaks.
2. A pressure regulator can become defective due to foreign material or a ruined diaphragm.


The result will be hard starting, poor idle quality, and lack or power. Burned spark plugs can result from operating with a lean air/fuel mixture, as well. replace this device if faults exist.

Toomuch fuel pressure. fuel regulator replaced

Where is the fuel pressure regulator on a 2003 oldsmobile alero?


There are 2 fuel lines connecting to the fuel injector rail. The larger line is the pressure line and the smaller line is the return line. The smaller line attaches to the fuel pressure regulator. You will notice that the regulator also has a vacuum line attached to it. If you are planning on changing it your self, let me know. There is a specific way to change it for safety reasons.
Let me know.
