1. Fuel System
Trouble and possible cause Corrective action
1. Insufficient fuel supply to the injector
1) Fuel pump will not operate.

Defective terminal contact.Inspect connections, especially ground, and tighten
securely.

Trouble in electromagnetic or electronic circuit parts. Replace fuel pump.
2) Lowering of fuel pump function. Replace fuel pump.
3) Clogged dust or water in the fuel filter. Replace fuel filter, clean or replace fuel tank.
4) Clogged or bent fuel pipe or hose. Clean, correct or replace fuel pipe or hose.
5) Air is mixed in the fuel system. Inspect or retighten each connection part.
6) Clogged or bent breather tube or pipe. Clean, correct or replace air breather tube or pipe.
7) Damaged diaphragm of pressure regulator. Replace.
2. Leakage or blow out fuel
1) Loosened joints of the fuel pipe. Retightening.
2) Cracked fuel pipe, hose and fuel tank. Replace.
3) Defective welding part on the fuel tank. Replace.
4) Defective drain packing of the fuel tank. Replace.
5) Clogged or bent air breather tube or air vent tube. Clean, correct or replace air breather tube or air vent tube.
3. Gasoline smell inside of compartment
1)Loose joints at air breather tube, air vent tube and fuel filler
pipe.Retightening.
2) Defective packing air tightness on the fuel saucer. Correct or replace packing.
3) Cracked fuel separator. Replace separator.
4. Defective fuel meter indicator
1) Defective operation of fuel meter unit. Replace.
2) Defective operation of fuel meter. Replace.
5. Noise
1) Large operation noise or vibration of fuel pump. Replace.
NOTE:
When the vehicle is left unattended for an extended period of time, water may accumulate in the fuel
tank.
To prevent water condensation:
1) Top off the fuel tank or drain the fuel completely.
2) Drain water condensation from the fuel filter.
Refilling the fuel tank:
Refill the fuel tank while there is still some fuel left in the tank.
Protecting the fuel system against freezing and water condensation:
1) Cold areas
In snow-covered areas, mountainous areas, skiing areas, etc. where ambient temperatures drop
below 0°C (32°F) throughout the winter season, use an anti-freeze solution in the cooling system.
Refueling will also complement the effect of anti-freeze solution each time the fuel level drops to about
one-half. After the winter season, drain water which may have accumulated in the fuel filter and fuel
tank in the manner same as that described under affected areas as below.
2) Affected areas
When water condensation is notched in the fuel filter, drain water from both the fuel filter and fuel tank
or use a water removing agent (or anti-freeze solution) in the fuel tank.
Observe the instructions, notes, etc., indicated on the label affixed to the anti-freeze solution (water
removing agent) container before use.
