INSPECTION
1. REMOVE EFI MAIN RELAY (Marking: EFI)
2. INSPECT EFI MAIN RELAY CONTINUITY
(a) Using an ohmmeter, check that there is continuity be-
tween terminals 1 and 2.
If there is no continuity, replace the relay.
(b) Check that there is no continuity between terminals 3 and
5.
If there is continuity, replace the relay.
3. INSPECT EFI MAIN RELAY OPERATION
(a) Apply battery voltage across terminals 1 and 2.
(b) Using an ohmmeter, check that there is continuity be-
tween terminals 3 and 5.
If there is no continuity, replace the relay.
4. REINSTALL EFI MAIN RELAY

ON−VEHICLE INSPECTION
1. CHECK FUEL PUMP OPERATION
(a) Connect the TOYOTA hand−held tester to the DLC3.
(b) Turn the ignition switch ON and push the TOYOTA hand−
held tester 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.
(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:
H−fuse (ALT 80A)
M−fuses (AM1 40A, AM2 30A)
Fuses (EFI 15A, IGN 7.5A)
EFI main relay
Circuit opening 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) Remove the 6 bolts, and disconnect the No.2 timing belt
cover.
(d) Remove the union bolt holding the fuel pipe to the delivery
pipe and gasket.
CAUTION:
Put a shop towel under the delivery pipe. Slowly loosen the
union bolt.
