Fuel injection system description
Fuel system
The fuel delivery system consists of the fuel tank (1), fuel pump (2), fuel filter (3), fuel feed hose (4), fuel delivery pipes (5) including fuel injectors (6) and (7), fuel pressure regulator (8). There is no fuel return hose. The fuel in the fuel tank is pumped up by the fuel pump and pressurized fuel flows into the injectors installed in the fuel delivery pipe. Fuel pressure is regulated by the fuel pressure regulator. As the fuel pressure applied to the fuel injectors (the fuel pressure in the fuel delivery pipe) is always kept at absolute fuel pressure of approx. 294 Kpa (2.9 Kgf/cm2, 41.8 Psi), the fuel is injected into the throttle body in conic dispersion when the injector opens according to the injection signal from the ecm.
The fuel relieved by the fuel pressure regulator flows back to the fuel tank.

Precautions
Keep away from fire or spark.
During disassembling, use care to minimize spillage of
gasoline.
Spilled gasoline should be wiped off immediately.

Throttle cable play inspection and adjustment
Inspect throttle cable play
initially at 1 000 km (600 miles, 2 months) and every
6 000 km (4 000 miles, 12 months) thereafter
Inspect and adjust the throttle cable play “a” as follows:
Throttle cable play “a”
2.0 – 4.0 Mm (0.08 – 0.16 In)
Remove the boot (1).

Valve clearance inspection and adjustment
Inspect valve clearance
initially every 24 000 km (14 500 miles, 48 months)
Inspection
Valve clearance adjustment must be checked and
adjusted, a) at the time of periodic inspection, b) when
the valve mechanism is serviced, and c) when the
camshafts are removed for servicing.

Continuity check
Measure resistance across coupler “b” (between “a”
and “c” in figure).
If no continuity is indicated (infinity or over limit), the
circuit is open between terminals “a” and “c”.
Disconnect the coupler “b” and measure resistance
between couplers “a” and “b-1”.
If no continuity ...
