NOTICE:
Do not start the engine.
(c) Select the following tester menus: DIAGNOSIS,
ENHANCED OBD II, ACTIVE TEST and FUEL
PUMP/SPD. Operate the fuel pump.
(d) Touch the fuel hose in the engine compartment to
check the fuel flow, and you will be able to hear the
sound of the fuel pump.
(e) Stop the fuel pump. If there is no fuel flow, the fuel
pump may not be operating. Check the fuel pump
circuit.
2. CHECK FUEL PRESSURE
(a) Check that the battery positive voltage is above 12
V.

REMOVAL
CAUTION:
Do not allow fuel to spray when removing the pipe
between the high pressure side fuel pump and the fuel
injector. The fuel in the pipe is highly pressurized.
1. DISCHARGE FUEL SYSTEM PRESSURE
CAUTION:
• The "DISCHARGE FUEL SYSTEM PRESSURE"
procedures must be performed before
disconnecting any part of the fuel system.
• After performing the "DISCHARGE FUEL SYSTEM
PRESSURE" procedures, pressure will remain in
the fuel line. When disconnecting the fuel line,
place a cloth or equivalent over fittings to reduce
the risk of fuel spray.
(a) Remove the console box (see page IP-16).
(b) Start the engine. After the engine has stopped, turn
the ignition switch OFF.
HINT:
DTC P0171/P0172 (system too lean) may be set.
