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.

Water hose inspection
Inspect the water hoses in the following procedures:
remove the side cowlings. Refer to “exterior parts
removal and installation” in section 9d (page 9d-
6).
Check the water hoses for crack, damage or engine
coolant leakage. If any defect is found, replace the
water hose wi ...
Fuel pump inspection
Turn the ignition switch on and check that the fuel pump
operates for a few seconds.
If the fuel pump motor does not make operating sound, inspect the fuel pump
circuit connections or inspect the fuel pump relay and to sensor. Refer to “fuel
pump relay inspection” and “dtc “c23” (p1651 ...
