3.
Turn the engine start switch to ON, and
then measure the fuel pressure within 3
seconds.
WARNING
Before measuring the fuel pressure, make
sure that the drain screw is tightened
securely.
NOTE:
The fuel pressure decreases 3 seconds after
the engine start switch is turned to ON.
4.
Start the engine, warm it up for 5 min-
utes, and then measure the fuel pres-
sure. If below specification, check the
high-pressure fuel line and the vapor
separator.
WARNING
• Do not loosen the drain screw while
measuring the fuel pressure. Loosening
the drain screw can cause fuel to spray
out creating a fire hazard.
• After measuring the fuel pressure, cover
the end of the hose with a clean, dry rag,
point the hose downward, and then
loosen the drain screw to drain the
remaining fuel from the hose and gauge.
• When storing the fuel pressure gauge,
make sure that the drain screw is tight-
ened securely.
Checking the pressure regulator
1.
Remove the cap.
2.
Disconnect the quick connector from the
fuel rail.
NOTE:
Before disconnecting the quick connector,
release the fuel pressure.
3.
Connect the special service tools as
shown.
4.
Disconnect the pressure regulator hose,
and then connect the special service
tools to the pressure regulator.
WARNING
• When connecting the fuel pressure
gauge, first cover the connection
between the gauge and adapter with a
clean, dry rag to prevent fuel from leak-
ing out.
• Gently screw in the gauge until it is
firmly connected.
5.
Start the engine and let it idle.
6.
Check that the fuel pressure reduces
when vacuum pressure is applied to the
pressure regulator. If the fuel pressure
does not reduce, replace the pressure
regulator.
