4. Remove the fuel pressure regulator mounting bolts(1).
(Tighten: Fuel pressure regulator mounting bolts to
9 N·m)
5. Remove the fuel pressure regulator.
6. Installation is in the reverse order of removal.
Installation Notes:
• Install new seals on the fuel pressure regulator sealing surfaces.
• Coat the surface of the fuel pressure regulator O-ring seal with clean engine oil before assembly.
• While installing the fuel pressure regulator, ensure that the fuel pressure regulator rotates smoothly in the fuel
distribution tube. If it does not rotate smoothly, the O-ring seal may have been damaged. Remove the fuel
pressure regulator and inspect the O-ring seal for damage.
Fuel Pressure Regulator Inspection
1. Connect a fuel pressure gauge to the inlet fuel pipe.
2. Start and idle the engine (note the fuel pressure).
3. Increase the engine speed to 2500 RPM (note the fuel pressure).
SPECIFICATION PRESSURE
Idle 350 kPa
2500 RPM 350 kPa

The battery, starting and charging systems operate in conjunction with one another, and must be tested as a com-
plete system. For correct operation of starting/charging systems, all components used in these 3 systems must per-
form within specifications. When attempting to diagnose any of these systems, it is important that you keep their
interdependency in mind. These components form two separate circuits, a high amperage circuit that feeds the
starter motor up to 150 amps, and a control circuit that operates on less than 20 amps.

Starter Motor Bench Test
Starter motor operation can be confirmed by performing
the following free-running bench test. This test can only
be performed with the starter motor removed from the
vehicle.1. Remove the starter motor from the vehicle (See Starter Motor Removal & Installation in Section 05
Starting and Charging).
2. Mount the starter motor securely in a soft-jawed bench vise. The vise jaws should be clamped on
the mounting flange of the starter motor (never
clamp on the starter motor by the field frame).
3. Connect a suitable volt-ampere tester and a 12 V battery to the starter motor in series, and set the
ammeter to the 100 A scale.
4. Install a jumper wire from the solenoid terminal to the solenoid battery terminal. The starter motor should oper- ate. If the starter motor fails to operate, replace the faulty starter motor assembly.
5. Adjust the carbon pile load of the tester to obtain the free running test voltage.
6. Note the reading on the ammeter and compare this reading to the free-running test maximum amperage draw.
7. If the ammeter reading exceeds the maximum amperage draw specification, replace the faulty starter motor assembly.
Starter Solenoid Test
This test can only be performed with the starter motor removed from the vehicle.
1. Remove the starter motor from the vehicle (See Starter Motor Removal & Installation in Section 05
Starting and Charging).
2. Disconnect the wire from the solenoid field coil ter- minal.
3. Check the solenoid for continuity between the sole- noid terminal and the solenoid field coil terminal
with a continuity tester. There should be continuity.
If there is continuity, go to Step 4. If not, replace
the faulty starter motor assembly.
4. Using a continuity tester, check for continuity between the solenoid terminal and the solenoid
case. There should be continuity. If not, replace the
faulty starter motor assembly.

Battery
Description
This vehicle is equipped with a single 12 V battery. All of the components of the battery system are located within the
engine compartment of the vehicle. The battery system for this vehicle contains the following components:
•Battery - The storage battery provides a reliable means of storing a renewable source of electrical energy within
the vehicle.
• Battery Cables - The battery cables connect the positive and negative charged battery terminal posts to the
vehicle electrical system.
• Battery Hold Down - The battery hold down hardware secures the battery in the battery tray.
• Battery Tray - The battery tray provides a secure mounting location in the vehicle for the battery and an anchor
point for the battery hold down hardware.
Operation
The battery is designed to store electrical energy in a chemical form. When an electrical load is applied to the ter-
minals of the battery, an electrochemical reaction occurs. This reaction causes the battery to discharge electrical
current from its terminals. As the battery discharges, a gradual chemical change takes place within each cell. The
sulfuric acid in the electrolyte combines with the plate materials, causing both plates to slowly change to lead sulfate.
At the same time, oxygen from the positive plate material combines with hydrogen from the sulfuric acid, causing the
electrolyte to become mainly water. The chemical changes within the battery are caused by the movement of excess
or free electrons between the positive and negative plate groups. This movement of electrons produces a flow of
electrical current through the load device attached to the battery terminals.
Removal & Installation
1. Disconnect the negative battery cable.
2. Disconnect the positive battery cable.
3. Remove the battery hold down retaining nuts (1).
4. Remove the battery.
5. Installation is in the reverse order of removal.
