Service Precaution
WARNING: IF SO EQUIPPED WITH A
SUPPLEMENTAL RESTRAINT SYSTEM (SRS),
REFER TO THE SRS COMPONENT AND WIRING
LOCATION VIEW IN ORDER TO DETERMINE
WHETHER YOU ARE PERFORMING SERVICE ON OR
NEAR THE SRS COMPONENTS OR THE SRS
WIRING. WHEN YOU ARE PERFORMING SERVICE
ON OR NEAR THE SRS COMPONENTS OR THE SRS
WIRING, REFER TO THE SRS SERVICE
INFORMATION. FAILURE TO FOLLOW WARNINGS
COULD RESULT IN POSSIBLE AIR BAG
DEPLOYMENT, PERSONAL INJURY, OR
OTHERWISE UNNEEDED SRS SYSTEM REPAIRS.
CAUTION: Always use the correct fastener in the
proper location. When you replace a fastener, use
ONLY the exact part number for that application.
ISUZU will call out those fasteners that require a
replacement after removal. ISUZU will also call out
the fasteners that require thread lockers or thread
sealant. UNLESS OTHERWISE SPECIFIED, do not
use supplemental coatings (Paints, greases, or other
corrosion inhibitors) on threaded fasteners or
fastener joint interfaces. Generally, such coatings
adversely affect the fastener torque and the joint
clamping force, and may damage the fastener. When
you install fasteners, use the correct tightening
sequence and specifications. Following these
instructions can help you avoid damage to parts and
systems.

Fuel Pump Relay
General Description
In order to control the FP operation, the FP relay is
provided. When the starter switch is turned to “ON”
position, the FP relay operates the FP for 2 seconds.When it is turned to “START” position, the Power Train
Control Module (PCM) receives the reference pulse from
the Ignition Control Module and it operates the relay,
again causing the FP to feed fuel.

Fuel Tube / Quick – Connect Fittings
Precautions
Lighting of Fires Prohibited.
Keep flames away from your work area to prevent the
inflammable from catching fire.
Disconnect the battery negative cable to prevent
shorting during work.
When welding or conducting other heat-generating
work on other parts, be sure to provide pretreatment
to protect the piping system from thermal damage or
spattering.
Cautions During Work
Do not expose the assembly to battery electrolyte or do
not wipe the assembly with a cloth used to wipe off spilt
battery electorolyte.
The piping wet with battery electrolyte cannot be used.
Be careful not to give a bending or twisting force to the
piping during the work. If deformed, replace with a new
piping.
Removal
1. Open the fuel cap to relieve the fuel pressure in the
tank.
If the fuel quick-connect fittings are dusty, clean with
an air blower, etc. and then remove it.
141RW016As some pressure may remain in the piping, cover the
connector with a cloth, etc. to prevent the splashing
of fuel in the first disconnection of the piping.
