1G-6 Fuel System:
Fuel Pump Inspection
B947H11706002
Turn the ignition switch ON and check that the fuel pump
operates for a few seconds.
If the fuel pump motor does not make operating sound,
inspect the fuel pump circuit connections or inspect the
fuel pump relay and TO sensor. Refer to “Fuel Pump
Relay Inspection” (Page 1G-7) and “DTC “C23” (P1651-
H/L): TO Sensor Circuit Malfunction” in Section 1A
(Page 1A-68).
If the fuel pump relay, TO sensor and fuel pump circuit
connections are OK, the fuel pump may be faulty,
replace the fuel pump with a new one. Refer to “Fuel
Pump Disassembly and Assembly” (Page 1G-11).
Fuel Discharge Amount Inspection
B947H11706003
WARNING
!
• Keep away from fire or spark.
• Spilled gasoline should be wiped off
immediately.
• Work in a well-ventilated area.
Inspect the fuel discharge amount in the following
procedures:
1) Lift and support the fuel tank. Refer to “Fuel Tank
Removal and Installation” (Page 1G-9).
2) Place a rag under the fuel feed hose (1) and
disconnect fuel feed hose from the fuel pump.
3) Connect a proper fuel hose (2) to the fuel pump.
4) Place the measuring cylinder and insert the fuel
hose end into the measuring cylinder.
5) Disconnect the fuel pump lead wire coupler (3).
6) Connect a proper lead wire into the fuel pump lead
wire coupler (fuel pump side) and apply 12 V to the
fuel pump (between (+) Y/R wire and (–) B/W wire)
for 10 seconds and measure the amount of fuel
discharged.
If the discharge amount is out of the specification,
the probable cause may be failure of the fuel pump
or clogged fuel filter.
NOTE
The battery must be in fully charged
condition.
Fuel discharge amount
222 ml (7.5/7.8 US/lmp oz) and more/10 seconds
7) After finishing the fuel discharge inspection, reinstall
the fuel tank. Refer to “Fuel Tank Removal and
Installation” (Page 1G-9).
NOTE
Connect the fuel feed hose to the fuel pump
until it locks securely (a click is heard).
