Component DescriptionNJEC0435The fuel injector is a small, precise solenoid valve. When the ECM
supplies a ground to the injector circuit, the coil in the injector is
energized. The energized coil pulls the needle valve back and
allows fuel to flow through the injector into the intake manifold. The
amount of fuel injected depends upon the injection pulse duration.
Pulse duration is the length of time the injector remains open. The
ECM controls the injection pulse duration based on engine fuel
needs.

ECM Terminals and Reference ValueNJEC0437Specification data are reference values and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.

12. Using the hexagon wrench (face to face: 6 mm, long-type)
(SST), remove the mounting bolts of the fuel injection pump
sprocket.
+It is not necessary to remove the washer of the fuel injection
pump sprocket.
JEF362Y
JEF363Y
13. Using the sprocket holder (SST), hold the fuel injection pump
sprocket to prevent falling.
+When the sprocket holder is installed, if the positioning stop-
per pin interferes, pull out the stopper pin approximately 10
mm (0.39 in), then install it.
+After the sprocket holder is installed temporarily, insert the
extension bar (SST) and Torx socket in the three holes A. After
positioning the holes, tighten the holder mounting bolts. (Refer
to the step 14 about the tool.)
+The length of the sprocket holder mounting bolts should be
approximately 15 mm (0.59 in) (M6 thread length).
+Make sure that the a- and b-faces of the sprocket holder con-
tact the bottom side of the sprocket 15 mm (0.59 in) (small
diameter side).
CAUTION:
Do not remove the sprocket holder until the fuel injection
pump is installed.
+After the sprocket holder is installed, pull out the positioning
stopper pin (SST) from the fuel injection pump sprocket.
JEF364Y
14. Using the extension bar [SST: whole length 43 mm (1.69 in)]
and the Torx socket (Q6-E12: commercially available), remove
the mounting bolts, them remove the fuel injection pump
toward the rear of the engine.
+Even after all the mounting bolts are removed, the fuel injec-
tion pump is still held by a dowel pin.
CAUTION:
Do not disassemble or adjust the fuel injection pump.
