Section 4 Fuel System
In addition to the ohmmeter test, check for smooth,
non-binding movement of the plunger. It is important
that the linkage between the fuel solenoid and the fuel
injection pump lever be properly adjusted to allow the
solenoid
plunger
to
fully
compress.
Improper
adjustment may cause burnout of the pull-in coil. If the
fuel solenoid setting is suspected to be incorrect, use the
following procedure to correct and see Figure 4-6.
Fuel Solenoid Adjustment Procedure
1. Remove the fuel solenoid linkage.
2. With the fuel solenoid’s plunger fully compressed,
align the linkage and check injection pump lever for
travel. The fuel solenoid should fully compress and
the injection pump lever should be 1.6 mm
(0.05 in.) before the lever reaches the stop
(internal full open) position.
Note:
The fuel solenoid must compress (bottom)
fully or burnout of the fuel solenoid pull-in
coil will occur.
3. If the alignment is not correct, check the linkage
and mounting brackets. Loosen locknuts and
adjust the ball joint’s length in or out to attain proper
alignment. Tighten the locknut.

4.6 Fuel Pump
The fuel pump transfers fuel from a source to the fuel
injection pump.
Fuel Pump Test Procedure
1. Remove the two leads from the terminals at the
bottom of the fuel pump. The pump terminals are
labeled (--) and (+). See Figure 4-7.
2. Connect the inlet side of the pump to a fuel source.
Disconnect the outlet hose from the fuel filter and
place the hose end in a container to catch the fuel.
3. Connect the positive (+) terminal of the 12-volt
battery to the positive terminal of the fuel pump.
Connect the negative terminal of the fuel pump to
the negative (--) terminal of the battery. You should
hear the pump operate and see the fuel discharge
from the pump outlet. Replace the pump if it does
not operate.
