FUEL PUMP
ON±VEHICLE INSPECTION
1. CHECK FUEL PUMP OPERATION
(a) Connect a hand±held tester to the Controller Area Net-
work Vehicle Interface Module (CAN VIM). Then connect
the CAN VIM to the Date Link Connector 3 (DLC3).
(b) Turn the ignition switch ON, and push the hand±held tes-
ter main switch ON.
NOTICE:
Do not start the engine.
(c) Enter the following menus: DIAGNOSIS / ENHANCED
OBDII / ACTIVE TEST / FUEL PUMP / SPD
(d) Please refer to the hand±held tester operator's manual
for further details.
(e) Check that the pulsation damper screw rises when the
fuel pump operates.
If operation is not as specified, check the fusible link, fuses, EFI
main relay, fuel pump, ECM and wiring connections.
(f) Turn the ignition switch off.
(g) Disconnect the hand±held tester and CAN VIM from the
DLC3.
2. CHECK FUEL PRESSURE
(a) Check the battery positive voltage is 12 V or more.
(b) Disconnect the negative (±) terminal cable from the bat-
tery.
(c) Remove the front fuel pipe from the LH delivery pipe. (See
page SF±27)
(d) Install the front fuel pipe and SST (pressure gauge) to the
delivery pipe with the 3 lower gaskets and SST (adaptor).
SST 09268±45014 (09268±41190, 90405±06167)
Torque: 39 N´m (400 kgf´cm, 29 ft´lbf)
(e) Wipe off any splattered gasoline.
(f) Reconnect the negative (±) terminal cable to the battery.
(g) Connect a hand±held tester to the DLC3. (See step 1 in
check fuel pump operation (a) to (e))

(h) Measure the fuel pressure.
Fuel pressure:
265 to 304 kPa (2.7 to 3.1 kgf/cm
2, 38 to 44 psi)
If pressure is high, replace the fuel pressure regulator.
If pressure is low, check the fuel hoses and connections, fuel
pump, fuel filter and fuel pressure regulator.
(i) Disconnect the hand±held tester and CAN VIM from the
DLC3.
(j) Start the engine.
(k) Measure the fuel pressure at idle.
Fuel pressure:
265 to 304 kPa (2.7 to 3.1 kgf/cm
2, 38 to 44 psi)
(l) Stop the engine.
(m) Check that the fuel pressure remains as specified for 5
minutes after the engine has stopped.
Fuel pressure: 147 kPa (1.5 kgf/cm
2, 21 psi) or more
If pressure is not as specified, check the fuel pump, pressure
regulator and/or injectors.
(n) After checking fuel pressure, disconnect the negative (±)
terminal cable from the battery and carefully remove the
SST to prevent gasoline from splashing.
SST 09268±45014
(o) Reinstall the front fuel pipe to the LH delivery pipe. (See
page SF±31)
3. CONNECT CABLE TO NEGATIVE BATTERY TERMI-
NAL
4. PERFORM INITIALIZATION (See page IN±20)
Some systems need initialization when disconnecting the cable
from the negative battery terminal.
5. CHECK FOR FUEL LEAKS (See page SF±1)

REMOVAL
1. REMOVE FUEL TANK ASSEMBLY (See page SF±34)
2. DISCONNECT FUEL SUCTION TUBE
Remove the 2 tube clips, and pull out the 2 fuel tubes.
NOTICE:

Before this operation, check the connector for dirt,
mud or other contamination. Clean if necessary.

Be careful of mud. The connector's O±ring, which
seals the pipe and connector, is easily contaminated.

Do not use any tool in this operation.

Do not bend or twist the nylon tube. Protect the con-
nector by covering it with a plastic bag.

When the pipe and connector are stuck, push and pull
the connector to release and pull the connector out
carefully.
3. REMOVE FUEL PUMP ASSEMBLY
(a) Using SST, loosen the fuel pump gauge retainer.
SST 09808±14020 (09808±01410, 09808±01420,
09808±01430)
HINT:
A rib on the fuel pump gauge retainer fits into a tip of the SST.
(b) Remove the fuel pump gauge retainer.
(c) Remove the fuel suction tube.
NOTICE:
Be careful not to bend the arm of the fuel sender gauge.
(d) Remove the gasket from the fuel tank.

NOTICE:

Check that there are no scratches or foreign objects
on the connecting part.

Check that the fuel tube joint is inserted securely.

Check that the tube joint clip is on the collar of the fuel
tube joint.

After installing the tube joint clip, check that the fuel
tube joint has not been pulled off.
