, 41.81 psi)
If the fuel pressure is lower than the specification, inspect the
following items:
* Fuel hose leakage
* Clogged fuel filter
* Pressure regulator
* Fuel pump
If the fuel pressure is higher than the specification, inspect the
following items:
* Fuel pump
* Pressure regulator
FUEL PUMP INSPECTION
Connect a proper lead wire into the fuel pump coupler (fuel
pump side) and apply 12 volts to the fuel pump (
above) and
check that the fuel pump operates.
If the fuel pump motor does not make operating sound, replace
the fuel pump with a new one.
If the fuel pump is OK, the cause may lie in the TO sensor or TO
sensor circuit. (

* Before removing the special tools, disconnect the
battery and release the fuel pressure slowly.
* Gasoline is highly flammable and explosive. Keep
heat, sparks and flame away.
