4.2 TROUBLESHOOTING (IF SYSTEM IS
NON-FUNCTIONING)
DANGER
During the following test, direct free end of
tube away from personnel and all sources of
ignition as this fuel is extremely flammable.
Avoid breathing vapors and contacting fuel
with skin. Never smoke during test.
FIGURE 20: COLD STARTING AID 23048
1. Check cylinder for hand tightness and fuel
supply (Fig. 20). Empty cylinder weight is
approximately 17 oz (480 g); full cylinder
weight is approximately 35 oz (990 g). If
cylinder is empty, replace it. Before
replacing cylinder, install new valve gasket
in solenoid valve.
2. If still not functioning, disconnect tubing at
solenoid valve fitting. Actuate solenoid
valve. (Ask an assistant to actuate solenoid
valve using the rocker switch on the dash-
board).
• If solenoid valve is non-functioning,
check electric circuit, (refer to wiring dia-
grams). If sound, remove and replace
the solenoid valve. If not, repair electric
circuit.
• If valve is functioning, reassemble valve
fitting and connect tube. Disconnect
tube at thermal cutout valve from port
"Tube from valve".
3. Actuate the solenoid valve.
• If fuel is not discharged from tube,
remove tube and blow out or replace.
• If fuel is discharged, connect tube to
thermal cutout valve, and disconnect
other tube.
4. Actuate the solenoid valve.
• If fuel is not discharged, replace the cut-
out valve.
NOTE
If engine coolant temperature is 90
o
F (32
o
C)
or over, it is normal that fuel is not discharged
as the valve is in closed position.
• If fuel is discharged, connect tube to
thermal cutout valve, and disconnect
tube from atomizer.
5. Actuate the solenoid valve.
• If fuel is not discharged from tube, fuel
line is clogged. Remove tube and blow
out or replace.
• If fuel is discharged, replace the
atomizer.
4.3 THERMAL CUTOUT VALVE QUICK
TEST
1. Engine coolant temperature must be below
90°F (32°C).
2. Temporarily disconnect tube at thermal
cutout valve from port "Tube to atomizer".
3. Actuate solenoid valve (Ask an assistant to
actuate solenoid valve by means of the
rocker switch on the dashboard). Fuel
should be discharged through the thermal
cutout valve.
DANGER
Avoid breathing vapors and contacting fuel
with skin. Never smoke during test.
4. Reconnect tube to thermal cutout valve.
5. Start engine, using cold starting aid if
necessary. Stop engine when it reaches
operating temperature.
6. Disconnect tube at thermal cutout valve as
in step 2, and repeat step 3. No fuel should
be discharged.
