TROUBLESHOOTING
2-2-2. Engine will not start (But starter motor runs)
In case of engine will not start while starter motor runs, generally trouble is caused by that fuel is not
supplied, supply amount of fuel is extremely low, or selection of fuel is not appropriate.
Check that fuel is supplied to inlet of fuel pump.
Reference Fig.: 2-2-1
Check point Check/Cause Action
1. Fuel Pump When starter switch is ON, measure voltage between fuel
pump terminal inlet wire LgW and chassis ground.
Standard voltage : 12 V or more
If above item is OK and fuel pump does not operate, fuel
pump is faulty.
•
•
Repair or replace fuel
pump.
2. Engine Stop Solenoid (1) When starter switch is ON, measure voltage between
engine stop solenoid terminal H inlet wire LgW and
chassis ground.
Standard voltage : 12 V or more
(2) When starter switch is START, measure voltage
between engine stop solenoid terminal P inlet wire RB
and chassis ground.
Standard voltage : 12 V or more
If above items (1) and (2) are OK and engine does not
start, engine stop solenoid is faulty.
•
Replace engine stop
solenoid.
3. Harness Connecting
Between Terminals
Measure resistance of harness connecting between
terminals.
Standard resistance : 10 Ω or less
If resistance is abnormal, harness is faulty.
•
•
Repair or replace
harness.
2-2-3. Engine does not stop running
Reference Fig.: 2-2-1
Check point Check/Cause Action
1. Engine Stop Solenoid (1) When starter switch is OFF, measure voltage between
engine stop solenoid terminal H inlet wire LgW and
chassis ground.
There is no electricity in normal condition.
(2) When starter switch is OFF, measure voltage between
engine stop solenoid terminal P inlet wire RB and
chassis ground
There is no electricity in normal condition.
If above items (1) and (2) are OK and engine dose not
stop after started, engine stop solenoid is faulty.
•
Replace engine stop
solenoid.
2. Harness Connecting
Between Terminals
Measure resistance of harness connecting between
terminals.
Standard resistance : 10 Ω or less
If resistance is abnormal, harness is faulty
•
•
Repair or replace
harness.
