FUEL PUMP RELAY
INSPECTION
1) Disconnect negative cable at battery.
2) Remove fuel pump relay (1) from relay box (2).
3) Structure of fuel pump relay is the same as that of main relay.
Check its resistance and operation using the same procedure as
that for main relay.
If found defective, replace.
FUEL INJECTOR RESISTOR
INSPECTION
1) With ignition switch OFF, disconnect resistor coupler.
2) Check resistor (1) for resistance.
Resistance: 1.9 – 2.1 Ω at 20_C, 68_F
If check result is not satisfied, replace.
FUEL CUT OPERATION
INSPECTION
NOTE:
Before inspection, check to make sure that gear shift lever is in
neutral position (with A/T model, selector lever in "P" range), A/C
is OFF and that parking brake lever is pulled all the way up.
1) Warm up engine to normal operating temperature.
2) While listening to sound of injector by using sound scope (2) or
such, increase engine speed to higher than 3,000 r/min.
3) Check to make sure that sound to indicate operation of injector
stops when throttle valve operation of injector stops when
throttle valve is closed instantly and it is heard again when en-
gine speed is reduced to less than about 2,000 r/min.

IDLE SPEED CONTROL SYSTEM
SYSTEM INSPECTION
NOTE:
Before inspection, check to make sure that:
– Gear shift lever is in neutral position (with A/T vehicle, selec-
tor lever in "P" range) and that parking brake lever is pulled
all the way up.
– Battery voltage is higher than 11 V.
– Throttle valve moves smoothly.
– Ambient temperature is higher than 0_C (32_F)
