ON-VEHICLE INSPECTION
1. CHECK FUEL PUMP OPERATION
(a) Connect a TOYOTA hand-held tester to the DLC3.
(b) Turn the ignition switch ON and TOYOTA hand-held tes-
ter main switch ON.
NOTICE:
Do not start the engine.
(c) Select the active test mode on the TOYOTA hand-held
tester.
(d) Please refer to the TOYOTA hand-held tester operator's
manual for further details.
(e) If you have no TOYOTA hand-held tester, connect the
positive (+) and negative (-) leads from the battery to the
fuel pump connector (See step 7).
(f) Check that there is pressure in the fuel inlet hose from the
fuel filter.
HINT:
If there is fuel pressure, you will hear the sound of fuel flowing.
If there is no pressure, check these parts:
Fusible link
Fuses
EFI main relay
Fuel pump
ECM
Wiring connections
(g) Turn the ignition switch to LOCK.
(h) Disconnect the TOYOTA hand- held tester from the
DLC3.
2. CHECK FUEL PRESSURE
(a) Check the battery positive voltage is above 12 V.
(b) Disconnect the negative (-) terminal cable from the bat-
tery.
(c) Purchase the new No.1 fuel pipe and take out the fuel
tube connector from its pipe.
