CONTINUITY INSPECTION
Turn the ignition switch OFF.
Remove the fuel pump relay (page 6-71).
Connect the ohmmeter to the switching side relay
terminals.
Connect the 12 V battery to the coil side relay termi-
nals.
There should be continuity between the relay termi-
nals while the battery is connected, and no continu-
ity when the battery is disconnected.
SWITCH LINE INSPECTION
Turn the ignition switch OFF.
Remove the fuel pump relay (page 6-71).
Short the relay connector terminals of the wire har-
ness side with a jumper wire.
Disconnect the fuel pump 5P connector (page 6-48).
Turn the ignition switch "ON".
Measure the voltage at the fuel pump connector of
the wire harness side.
If the battery voltage appears, the engine stop relay
switch line is normal.
If the battery voltage does not appear, inspect the
following:
– Open circuit in Black/White wire between the
engine stop relay and fuel pump relay
– Open circuit in Brown wire between the fuel
pump relay and fuel pump
