FUEL SYSTEM SERVICE
WARNING: Relieve fuel system pressure prior to servicing any fuel
system component (fuel injection models).
HALOGEN BULBS
Halogen bulbs contain pressurized gas which may explode if
overheated. DO NOT touch glass portion of bulb with bare hands. Eye
protection should be worn when handling or working around halogen
bulbs.
RADIATOR CAP
CAUTION: Always disconnect the fan motor when working near the
radiator fan. The fan is temperature controlled and could
start at any time even when the ignition key is in the OFF
position. DO NOT loosen or remove radiator cap when cooling
system is hot.
RADIATOR FAN
WARNING: Keep hands away from radiator fan. Fan is controlled by a
thermostatic switch which may come on or run for up to 15 minutes even
after engine is turned off.
WARRANTY INFORMATION
CAUTION: Due to the different warranties offered in various regions
and the variety of after-market extended warranties
available, please refer to the warranty package that came
with the vehicle to verify all warranty options.
FUSES & CIRCUIT BREAKERS
FUSE PANEL LOCATION
The electrical system is protected against shorts by fuses
that are designed to fail, to prevent damage to the wire harness. The
fuse block is located under the instrument panel on the driver's side.
If a fuse is blown, locate the cause before replacing the fuse. Spare
fuses are contained in the fuse block.

DISTRIBUTOR
NOTE: Eclipse, Mirage 1.8L, Montero, Montero Sport 3.0L and 3000GT
DOHC use Distributorless Ignition System (DIS). All other
models use distributor type ignition systems with
non-serviceable distributors on which only the rotor and
distributor cap can be changed.
FUEL SYSTEM
* PLEASE READ THIS FIRST *
WARNING: Always relieve fuel pressure before disconnecting any fuel
injection-related component. DO NOT allow fuel to contact
engine or electrical components.
FUEL SYSTEM PRESSURE RELEASE
Relieving Fuel Pressure
1) On Diamante, disconnect fuel pump harness connector at
fuel tank from underneath vehicle. On Montero and Montero Sport,
remove cargo compartment carpet, remove access plate and disconnect
fuel pump harness connector. On all other models, remove rear seat
cushion and remove access plate (if required) to disconnect fuel pump
harness connector.
2) On all models, start engine. Let engine run until it
stops. Turn ignition off. Disconnect negative battery cable. Connect
fuel pump harness connector. Reinstall rear seat (if necessary.)
FUEL PUMP
Removal & Installation (Diamante, Eclipse, Galant & Montero)
1) Fuel pump assembly is located inside fuel tank. Release
fuel pressure. See FUEL SYSTEM PRESSURE RELEASE . Remove access panel
under seat, in trunk or in rear cargo area. Disconnect electrical
connectors and fuel hoses at fuel tank.
2) Remove fuel filler hose from fuel tank. Remove fuel pump
assembly. To install, reverse removal procedure. Tighten nuts to
specification. See TORQUE SPECIFICATIONS .
Removal & Installation (Mirage, Montero Sport & 3000GT)
1) Fuel pump assembly is located inside fuel tank. Release
fuel pressure. See FUEL SYSTEM PRESSURE RELEASE . Raise vehicle on
hoist. Drain fuel into suitable container. Disconnect electrical
connectors and breather/fuel hoses at fuel tank.
2) Remove fuel filler hose from fuel tank. Support fuel tank
with transmission jack. Remove nuts securing fuel tank. Remove fuel
tank from vehicle. Remove fuel pump assembly. To install, reverse
removal procedure. Tighten nuts to specification. See
TORQUE SPECIFICATIONS .
FUEL RAILS & INJECTORS
WARNING: Use a rag to cover fuel hose connection before disconnecting
high pressure fuel hose at fuel rail. Some residual fuel
pressure may still be in system.
CAUTION: DO NOT drop injectors while removing or installing fuel rail.
