Hello and good day:

First look for this little Gem... It should be located on top of the engine near the Fuel Rail.


fuel pressure regulator.
a top-mount, bottom-sense fuel delivery module containing:
the electric fuel pump which provides pressurized fuel to the engine.
the fuel level sensor.
an inlet filter.
a check valve which maintains system pressure after the pump is shut off.
fuel pressure regulator.

Most vehicles have a fuel pressure test port somewhere on the fuel rail, use a flash light to locate it on your engine or consult a [COLOR=green !important][COLOR=green !important]car[/COLOR][/COLOR] repair manual. With the engine off remove the protective cap and attach the fuel pressure gauge. Support the gauge for observation; now turn the key to the on position. The fuel pressure gauge should jump up to your system pressure, in most cases 45 p.s.i. to 55 p.s.i. is standard in port injection system and 14 p.s.i. to 18 p.s.i. in TBI (throttle body injection) systems. When testing fuel pressure may vary slightly but should be pretty close to spec. To find exact pressure for your vehicle consult a [COLOR=green !important][COLOR=green !important]car[/COLOR][/COLOR] repair manual. (Note: Some cars do not have a test port; in this case you must use a fuel filter bypass hose to "tee" the fuel pressure gauge in for testing)
Most vehicles utilize a fuel injection system to deliver fuel to the engine. Correct fuel system pressure is essential for proper engine operation, in fact many engine run-ability problems can be related to weak fuel system pressure. A fuel injection system contains a fuel pump to supply fuel from the tank into the fuel system. The fuel filter cleans fuel before fuel enters the fuel injectors. The fuel pressure regulator adjusts fuel system pressure depending on the load of the engine.

Found it. Thanks much for the information.
