engme The fuel pump will run for about
2
seconds, and
fuel pressure will rise.
Wrap a shop rowel

atracilmem to soak
up any spilled fuel
Turn the ignition switch to OFF (0).
B. Repeat step 6 two or three times, and check that
there is no leakage in the fuel supply system.
9. Install the passenger seat under cover (page 3-6).
FUEL PRESSURE TEST
Relieve the fuel pressure (page 6-31).
Disconnect the quick connect fitting from the fuel
injector (page 6-31).
Attach the special tools between the injector and
fuel feed hose.

Pressure manifold hose 07AMJ-HW3A 100
Adapter, male 07AAJ-S6MA200
Adapter, female 07AAJ -S6MA400
Connect the fuel pump 5P connector.
Start the engine and let it idle.
Read the fuel pressure.
Standard: 336 - 350 kPa (3.43 - 3.57
kgf/c m ~,
49 - 51 psi)
If the fuel pressure is higher than specified pressure,
replace the fuel pump assembly (faulty fuel pump or
fuel pressure regulator).
If the fuel pressure is lower than specified pressure,
inspect the following;
- fuel flow (page 6-36)
- pinched or clogged fuel feed hose
- fuel pump (page 6-36)
Disconnect the fuel pump 5P connector, start the
engine and let it idle until it stalls to relieve the fuel
pressure.
Remove the special tools from the fuel injector and
fuel feed hose.
Connect the quick connect fitting to the fuel injector
(page 6-33).
