Hi, if you have the V-6 engine, the regulator is under the upper intake manifold. If you have the 4 cylinder, it's at the end of the rail as shown below.

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!

MY 1991 VOLVO 240 WILL START,RUN FOR ABOUT 15 SECONDS, AND QUIT. AFTER THAT IT WILL TURN OVER, BUT WILL NOT START UNTIL IT SITS FOR A FEW MINUTES. THEN THE PROCESS REPEATS.ANY THOUGHTS ON MY PROBLEM?


Try replacing the fuel filter and locate the fuel pressure regulator it should be located on the top of the motor at the area where the beginning fuel rail is, ( the fuel rail feeds the fuel injectors) if you notice the the pressure regulators vacuum hose is broken replace also if the pressure regulator appears to be wet with gas replace it. The fuel pump may be bad check for appropriate pressure at access valve on fuel rail it should be a minimum of 30 psi fuel pressure.

What happens when the fuel pressure regulator goes bad?


The motor more than likely won't start or it could flood out with gas.
Fuel pressure regulator controls fuel pressure. You should have 30psi at the fuel rail for the motor to start.

This vehicle is most likely a returnless system,only one fuel line to the fuel rail. If it is returnless the fuel pressure regulator is part of the fuel pump module in the tank.
