Keep in mind that you have several components there:
- Fuel Pump Sender Assembly,
- Fuel Pressure Regulator,
- Fuel Rail Assembly, and
- Fuel Injectors.

1.- Fuel Pump (Sender Assembly) - TESTING
Refer to the accompanying charts for fuel pump diagnosis and testing.

The fuel injection system remains under pressure, even after the engine has been turned OFF. The fuel system pressure must be relieved before disconnecting any fuel lines. Failure to do so may result in fire and/or personal injury.

2.-
Fuel Pressure Regulator - REMOVAL & INSTALLATION

(the fuel pressure regulator, which is located on the fuel rail assembly)

NOTE:
Before removing the fuel regulator assembly, place a clean shop towel under the regulator to catch any fuel drips

  1. Properly relieve the fuel system pressure.
  2. If not done already, disconnect the negative battery cable.
  3. On the 3.1L engine, remove the intake manifold plenum, as outlined in .
  4. On the 2.4L engine, remove the fuel rail. Refer to procedure earlier in this section.
  5. Detach the vacuum line from the regulator.
  6. Place a shop towel under the regulator to catch any fuel that may drip out. Unfasten the fuel pressure regulator retaining screw, then remove the regulator by twisting and pulling it from the fuel rail.
  7. Remove and discard the O-ring seal. Inspect the filter screen for contamination and replace if necessary.
To install:
  1. Prior to assembling the pressure regulator to the fuel rail, lubricate the new rail-to-regulator O-ring seal with clean engine oil.
  2. Place the O-ring on the pressure regulator and install the pressure regulator to the fuel rail.
  3. Install the retainer or coat the regulator mounting screws with an approved thread locking compound and secure the pressure regulator in place. Tighten the mounting screw to 76 inch lbs. (8.5 Nm).
  4. If removed, install the fuel rail assembly to the engine.
WARNING The fuel return pipe must be connected before tightening the regulator retaining screw to prevent the regulator from rotating. Rotation of the regulator could damage the retainer and spacer bracket and lead to a fuel leak at the regulator inlet.
  1. Connect the fuel feed line and return line to the fuel rail assembly, use a backup wrench on the fittings to prevent turning.
  2. Attach the vacuum line to the regulator.
  3. On the 3.1L engine, install the intake manifold plenum.
  4. Connect the negative battery cable. Turn the ignition to the ON position for two seconds, then turn it to the OFF position for ten seconds. Turn again to the ON position and check for fuel leaks.

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

More than likely it is going to be either the knock sensor. Or the cam sensor. Both of these will shut off ignition immediately. That sounds like what is going on with your truck. I would pull one of the spark plugs to verify that you are losing ignition.

Low fuel pressure is not from the timing. It is from the pump or regulator.

Does a 2000 chevy malibu have a fuel reset button and where? it just died while at a stop sign, so we thought it was out of gas. we put gas in and it still will not start.


Hello mellissa, the 2000 malibu does not have a fuel reset switch. Check the fuel pump relay in the fuse box under the hood. Check for fuel pressure. You should be able to hear the fuel pump come on for a few seconds when you turn the key to the run position....Your fuel pump might have failed.
I hope this helps.

2000 Malibu will not idle


4000 rpm and flucuating is normal. rpm limiter. If its too rich need to find out why. first thing to check is the fuel pressure regualtor, take off the vac hose to it, and if there is fuel in the hose, the regulator is bad and will need replacement. that is only 1 thing that could cause rich running but is always the first thing to check. if its running that bad there should be a service eng soon light on.
