SOURCE: 2000 Chevy Venture Fuel Pressure Regulator

use the pressure test port on the top of the engine, it is on the fuel rail that supplies fuel to the injectors, looks like a tire valve, will have a plastic cap on it.

SOURCE: fuel pressure regulator had no vacuum line connected

another engineers wet dream. think of it this way . what is normally in the intake when the engine is running.. answer vacume, hence the regulator gets its vacume without a hose connected to it as its already in a full time vacume chamber.no hose required . ps be carefull to seat the regulator and o rings securely into the housing befor you reattach the secureing metal clip.
good luck chris

SOURCE: do i need to relieve

yes it's under pressure can can do it by starting the car pull the fuel pump fuse and allow it to die try and restart the car a couple times with the fuse removed after that the pressure should be relieved. if you have a fuel pressure gauge you can do it by connecting it to the strader valve and relieving it that way also

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 ?

You should have a test port on the Fuel Supply rail, use a tool from a local auto parts "Tool Loaner program" where you can borrow tools for free,w/a deposit of course,then follow the steps provided;

MPI Fuel System Pressure Test

The MPI fuel system used in vehicles equipped with a 4.OL engine employs a vacuum balanced pressure regulator. Fuel pressure should be approximately 55-69 kPa (8-10 psi) lower with the vacuum line attached to the regulator than with the vacuum line disconnected. System fuel should be 214 kPa (31 psi) with the vacuum line connected to the regulator and 269 kPa (39 psi) with the vacuum line disconnected. CAUTION: Some fuel may be discharged when connecting fuel gauge to fuel rail.
  1. Connect a 0-414 kPa (0-60 psi) fuel pressure gauge to test port pressure fitting on fuel rail (Fig. 7).
  2. Remove vacuum line from pressure regulator.
  3. Start the vehicle.
  4. Note gauge reading. With vacuum line disconnected, fuel pressure should be approximately 269 kPa (39 psi).
  5. Connect vacuum line to pressure regulator. Note gauge reading. Fuel pressure should be approximately 214 kPa (31 psi).
  6. If fuel pressure is not approximately 55-69 kPa (8-10 psi) higher with vacuum line removed from regulator, inspect pressure regulator vacuum line for leaks, kinks or blockage. CAUTION: Fuel pressure will rise to as much as 655 kPa (95 psi) when the fuel return tine is pinched shut, shut engine down immediately after pinching oft fuel return line.
  7. If fuel pressure is low, momentarily pinch shut the hose section of the fuel return line. If fuel pressure remains low, inspect the fuel supply line, fuel filter, and fuel rail inlet for blockage. If fuel pressure rises replace fuel pressure regulator.
  8. If fuel pressure is above specifications, inspect the fuel return line for kinks and blockage.

Capacity Test

  1. Remove the cap from the pressure test port in the fuel rail.
  2. Connect a 0-414 kPa (0-60 psi) fuel pressure gauge to the pressure fitting on the fuel rail (Fig. 7).
  3. Start the vehicle. Pressure should be approxi- mately 214 kPa (31 psi) with the vacuum hose connected to the pressure regulator and 269 kPa (39 psi) with the vacuum hose removed from the pressure regulator.
  4. If the pressure is not to specification, check the following before replacing the fuel pressure regulator:
  • 4a - Inspect the fuel supply and return lines/hoses for kinks or restricting bends
  • 4b - Check the fuel pump flow rate. A good fuel pump will deliver at least 1 liter of fuel per minute with the fuel return line pinched off. If the fuel pump does not pump adequately, then inspect the fuel system for a plugged fuel filter or fuel pump inlet filter (sock). Fuel pump flow rate can be done by connecting one end of an old A/C gauge hose to the fuel test port on the fuel rail and inserting the other end of the hose into a container of at least 1 liter capacity. Run the fuel pump by installing a jumper wire into diagnostic connector terminals D1-5 and D1-6. Be sure to pinch off the fuel return line or most of the fuel will be returned to the fuel tank.

Car runs fine at times then will not start. Sprayed carb cleaner in air filter and then it starts but dies when i start. The next day car starts and runs fine.


It sounds like your car isn't getting the proper amount of gas. You say your mechanic changed the fuel pump and the regulator. Id have him run a diagnostic tool on it to see if it throws any other codes. Its getting fire. Try changing the FUEL FILTER. it maybe clogged. maybe the pressure regulator is not giving it enough pressure to push the gas into the engine or maybe the fuel pump is only working at times. Does it run good and then start to spit and spudder then die? if so its not getting gas some how. Idk if you can adjust the pressure regulator or not. i mostly work on old school cars.

How to change a fuel regulator on a 2000 alero


the regulator is located at the end of the fuel rails where the gas comes from the tank to the motor, just a couple of bolts hold it in place, and the vacume line on it pulls right off, however you will need a fuel line disconnection tool to remove the fuel lines coming from the tank to the regualtor, i paid like 12 bucks for mine, it just slides on the line and into the coupler then the line and coupler seperate, be sure to releave fuel pressure from the motor before taking the old one off to prevent spray and a gasy mess during diconection.

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.


44dcbf8.jpg Fig. Cutaway view of a typical fuel 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.

Fig. Exploded view of the fuel pressure regulator mounting-3.1L and 3.4L (VIN E) engines
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.

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.

I suspect fuel pump problem how do I check fuel pressure, what tools do I need


There should be a Schrader valve on the fuel rail (looks like a valve stem on a tire, it is metal).

You need to connect a fuel pressure gauge to that valve and do the following test:

  1. Relieve fuel pressure.
  2. Remove the 12 mm sealing nut from the fuel rail. Attach the fuel pressure adapter nut, 12 mm (90201 - P0A - 003) and the special tool.
  3. Start the engine. Measure the fuel pressure with the engine idling and the vacuum hose of the fuel pressure regulator disconnected from the fuel pressure regulator and pinched. If the engine will not start, turn the ignition switch on, wait for two seconds, turn it off, then back on again and read the fuel pressure. Pressure should be: 260 - 310 kPa (2.7 - 3.2 kgf/sq.cm, 38 - 48 psi)
  4. Reconnect vacuum hose to the fuel pressure regulator. Pressure should be: 210 - 250 kPa (2.1 - 2.8 kgf/sq.cm, 30 - 37 psi) If the fuel pressure is not as specified, first check the fuel pump. If the fuel pump is OK, check the following:
    • If the fuel pressure is higher than specified, inspect for:
    • Pinched or clogged fuel return hose or line.
    • Faulty fuel pressure regulator.
    • If the fuel pressure is lower than specified, inspect for:
    • Clogged fuel filter.
    • Faulty fuel pressure regulator.
    • Fuel line leakage.
