    no fuel pressure on fuel rail was fixed by replacing the fuel pump. all went well till i put the tank back on the hanger straps, those dumb engineers who designed the hanger bokts made them too short,making the tank hanging areal difficult. thanks for the fuel pump tip

Where is the fuel pressure regulator located?


The regulator is attached to the fuel rail, under the fuel rail cover. Here is a drawing... it is item #4. The drawing is an exploded view - follow the trace-line from the part to the rail cross-over and you see where it connects. Here is the R/R procedure from AUTOZONE....

  1. Disconnect the negative battery cable.
  2. Relieve the fuel system pressure.
  3. Remove the fuel rail cover.
  4. Remove the fuel rail.
  5. Remove the fuel tube bracket attaching screw, then remove the bracket.
  6. Unfasten the pressure regulator attaching screw and separate the regulator from the fuel rail assembly.
  7. Remove the fuel outlet tube retaining clip, then remove the tube from the pressure regulator.
  8. Remove the pressure regulator inlet and fuel outlet tube O-rings, then discard.
  9. Inspect the filter screen for contamination. If contaminated, replace it with a new one.
To install:
  1. Lubricate the new pressure regulator inlet and outlet tube O-rings with clean engine oil and install.
  2. Install the fuel outlet tube into the regulator and install the retaining clip.
  3. Push the pressure regulator into the fuel rail and install the retaining screw. Tighten the screw to 89 inch lbs. (10 Nm).
  4. Install the fuel tube bracket and retaining screw. Tighten the screw to 44 inch lbs. (5 Nm).
  5. Install the fuel rail assembly.
  6. Connect the negative battery cable.
  7. With the engine off, turn the ignition switch to the ON position for 2 seconds, then turn it to the OFF position for 10 seconds. Again turn it to the ON position and check for fuel leaks.

Hope this helps!

1999 Olds Alero will not start until press is released in fuel injector rail


It could be that the fuel pressure is too high. This COULD cause the injectors to not fire when they are triggered. Once you bleed the pressure and the car is running, there is enough flow to keep the pressure at a manageable level. I would get a fuel pressure gauge and check the pressure at the rail. You may find a new fuel pressure regulator will fix your issue.

Have a 2007 mitsubishi L200 4D56 command rail engine that will not run. The only way I can make this engine run is to unplug the pressure sensor located on the end of the fuel rail. Even then, it will only...


In your case the pressure sensor is faulty and needs to be replaced. 1) Stores pressurized fuel (25 to 180 MPa) that has been delivered from the supply pump and distributes the fuel to each cylinder injector. A rail pressure sensor and a pressure limiter valve are adopted in the rail. 2) The rail pressure sensor (Pc sensor) detects fuel pressure in the rail and sends a signal to the engine ECU, and the pressure limiter controls the excess pressure. This ensures optimum combustion and reduces combustion noise. ---- Rail • The rail is mounted between the supply pump and the injector, and stores the high-pressure fuel. --------- Injector:-------- • This injector replaces the conventional injection nozzle, and achieves optimal injection by effecting control in accordance with signals from the engine ECU. Signals from the engine ECU determine the duration and timing in which current is applied the injector. This in turn, determines the quantity, rate and timing of the fuel that is injected from the injector. ------------ Rail Pressure Sensor (Pc Sensor) 1) The pressure sensor detects the fuel pressure of the rail, and sends a signal to the engine ECU. The sensor is made from a semiconductor that uses the Piezo resistive effect to detect changes in electrical resistance based on the pressure applied to the elemental silicon. In comparison to the old model, this sensor is compatible with high pressure. ---------- There is a service manual for how the fuel rail sensor and fuel system works.Its for mitsubishi L200 4D56.----------- Click this link for referring the service manual:--- http://technoanswers.blogspot.com/2011/06/service-manual-for-mitsubishi-l200-4d56.html ----------- This should help.thanks.Helpmech.

I need to access the fuel injectors in my 98 wrangler, but i dont know how to get to them


FIRST NEED TO RELIEF FUEL PRESSURE REMOVE GAS CAP RELIEF GAS PRESSURE IN FUEL TANK.THEN REMOVE FUEL PUMP RELAY THEN START ENGINE UNTIL IT DIES LACK OF FUEL,CRANK ENGINE OVER FEW MORE TIMES MAKE SURE FUEL OUT OF FUEL LINES. THEN YOU NEED TO REMOVE AIR CLEANER CROSS OVER TUBE ABOVE FUEL RAILS. DISCONNECT LINES AT THE ENDS OF THE FUELS RAILS ASSEMBLY. MARK AND DISCONNECT THE FUEL INJECTOR WIRE HARNESS CONNECTORS. REMOVE THE FUEL RAIL RETAINING BOLTS, DISCONNECT THE VACUUM LINE FROM THE FUEL PRESSURE REGULATOR. REMOVE THE FUEL RAIL ASSEMBLY FROM THE ENGINE. IF YOU HAVE AUTOMATIC TRANSMISSION REMOVE THE THROTTLE PRESSURE CABLE AND BRACKET TO REMOVE THE FUEL RAIL ASSEMBLY.TO REMOVE FUEL INJECTORS JUST REMOVE CLIPS THAT RETAIN FUEL INJECTORS IN FUEL RAIL. BESURE GO TO DEALERSHIP BUY NEW FUEL INJECTORS O - RINGS.APPLY A SMALL AMOUNT OF ENGINE OIL TO THE O - RINGS TO AID IN INSTALLATION. TORQUE FUEL RAIL BOLTS TO 100 INCH LBS.

Where is the fuel tank pressure sensor located in a 1998 Buick Regal Supercharged?


Hi,

I believe that I can help you.

Go to your throttle body.
  • A large diameter fuel rail is attached to the top of the intake manifold and supplies fuel to all of the injectors.
  • A fuel pressure cap is located on the rail for quick pressure checks,
  • The electric fuel pump is attached to the fuel sender assembly in the fuel tank. It pumps fuel constantly from the tank, through the fuel rail on to the engine and back to the tank.
  • The fuel pressure regulator that is mounted on the fuel rail maintains pressure across the injectors under all operating conditions.
Unfortunately, my scanner is inoperative and I cannot provide you with a diagram

I need to replace de fuel presurre sensor in a pontiac montana ,do i have to just replace the sensor ,o the sensor came with the fuel pump?thank you


Replacing the fuel pressure regulator, involves just replacing the regulator at the end of the fuel rail in the engine compartment, but fuel pressure sensor - does this mini-van have a fuel pressure sensor?
replacing the fuel pressure regulator: (1) locate it at the end of the fuel rail in the engine compartment,
(2) relieve fuel system pressure (3) disconnect fuel pressure regulator vacuum line. (4) remove fuel pressure regulator retaining screw (retain for re-use (5) using a shop towel to catch spilled fuel, lift & twist Fuel pressure regulator to remove it from the fuel rail. (6) remove/discard retainer and spacer bracket from the fuel rail. (7) remove fuel pressure regulator from the engine fuel return pipe. (8) remove/discard Fuel Pressure Regulator inlet O-ring (9) Check Fuel Pressure Regulator filter screen for contamination - if contaminated, replace Fuel Pressure Regulator. (10) Lubricate new Fuel Pressure Regulator inlet O-ring with clean engine oil & install onto the Fuel Pressure Regulator inlet. (11) Install the fuel return pipe onto the Fuel Pressure regulator (12) Install new retainer & spacer bracket into the slot on the fuel rail.
(13) Install Fuel Pressure Regulator onto Fuel Rail & tighten Engine Fuel Return Pipe nut to 13 ft-lbs (17 Nm). (14) connect Fuel Pressure Regulator vacuum line, (15) Install Fuel Pressure Regulator attachng screw & tighten to 76 in-lbs (8.5 Nm). (16) Inspect & verify that retainer & spacer bracket is engaged in the slots on the fuel rail. Grasp & pull on the Fuel Pressure Regulator.
to ensure that the Fuel Pressure Regulator is properly seated. (17) inspect for fuel leaks with this
procedure: On 2sec,(holy rollers), off 10sec will be left on, inspect for leaks while running.

On my toyota twincam 4 A-GE motor the fuel is not been returned to the tank. from the tuel rail. there is a high amount of pressure on the feul rail inlit.what could be the problem?


With fuel pressure gauge hook up, check reading, then disconnect vacuum hose from fuel pressure regulator, regulator sit on injector fuel rail, fuel pressure should go up, if it don't fuel pressure regulator stuck close, and not letting fuel back into fuel tank, hope this was very helpful.
