e. Transmission Neutral Start Feature
The transmission neutral start feature is a safety feature
designed to prevent the engine from starting with the
transmission in (F) FORWARD or (R) REVERSE.
Shifting into (N) NEUTRAL (Fig. 9 -60, 1) activates the
neutral start relay (Fig. 9-59, 1) located in the fuse and
relay panel (2). When the travel select lever is in (N)
NEUTRAL, electrical power flows to the starter relay,
allowing the starter to engage and start the engine.
Figure 9-59 Neutral Start Relay Location
Test the transmission neutral start circuit as follows:
• The starter MUST NOT operate with the travel
select lever in (F) FORWARD or (R) REVERSE.
• The starter MUST NOT operate when the park
brake is OFF (disengaged).
• The starter MUST operate with the travel select
lever in (N) NEUTRAL.
If the starter fails to turn the engine with the travel select
lever in (N) NEUTRAL (Fig. 9-60, 1) and the ignition key
switch is in the START position, refer to Section 9.7.7,
“Engine Start Circuit and Troubleshooting.” The
NEUTRAL position contacts in the shift switch (2) are
non-repairable. Replace the switch if defective.

9.15.2 Fuel Shut-off Solenoid
The fuel shut-off solenoid (Fig. 9-61, 1), located on the
rear of the fuel injection pump, is a solenoid that lets fuel
enter the injection pump when the ignition key switch is
turned to the START or RUN positions. The fuel shut-off
solenoid is connected to mechanical linkage (3).

a. Fuel Shut-off Solenoid Removal
1. Disconnect the negative (-) battery cable at the
negative battery terminal.
2. Disconnect the wiring connector at the fuel shut-off
solenoid lead (Fig. 9-61, 2), then remove the fuel
shut-off solenoid (1) from the fuel injector pump.
3. Remove the two bolts securing the solenoid to the
mounting plate. Remove the nut holding the linkage
to the arm on the fuel injection pump. Save the
hardware for later reuse.
