The fuel system consists of many tiny holes and
spaces that allow the movement of fuel from one place
to another. These holes and spaces are milled to
extremely high precision. This is especially true of the
fuel injectors.
The fuel injector is very sensitive to foreign material.
Foreign material will result in fuel system breakdown.
Exercise great care not to allow the entry of foreign
material into the fuel system or fuel injectors during the
removal and installation procedure.
Caution:
To avoid electric shock;
Set the switch to the ‘OFF’ position and disconnect
battery negative cable before checking or repairing the
fuel injector, wiring or/and connectors.
