with a feeler gauge. Renew the oil pump if this
clearance exceeds the Specifications.

(5) Check the cover plate for wear and scoring
and renew as necessary. (6) Check the relief valve plunger and spring for
wear or damage. Renew any faulty components as
necessary.
TO ASSEMBLE AND INSTAL

Assembly is a reversal of the dismantling proce-
dure with attention to the following points:

(1) Liberally lubricate all components with clean
engine oil before assembly. (2) Install the relief valve plunger and spring into
the pump housing and install the relief valve
plug
using a new sealing washer. Tighten the plug securely. (3) Install the outer rotor into the pump housing with the F mark on the rotor facing towards the cover
plate, if applicable. Install the inner rotor ensuring that
it is correctly meshed with the teeth of the outer rotor.

(4)
Install the cover plate to the oil pump housing
and tighten the retaining screws to the specified
torque. (5) Install a new oil seal to the front of the oil
pump housing. Ensure that the lip of the oil seal faces
the inside of the oil pump housing. (6) If necessary, install the oil pressure gauge
sender unit.
(7) Turn the inner rotor in the oil pump housing.
Ensure that the oil pump rotates freely. (8) Ensure that the mating surfaces of the oil
pump and cylinder block are thoroughly clean. Coat
the oil pump gasket with an oil resistant sealer and
install the oil pump and gasket to the cylinder block. It
may be necessary to turn the oil pump slightly to align
the inner rotor and crankshaft. Tighten the retaining
bolts to the specified torque.
NOTE: Ensure that the oil seal installed to
the oil pump is not damaged when the oil
pump is positioned on the crankshaft.

(9) Install the camshaft drive belt inner cover.
(10) Install the water pump using a new O ring.
Coat the water pump and the engine block mating
surfaces with Dow Corning silicone grease or equiva-
lent. Do not fully tighten the water pump retaining
bolls at this stage. (11) Install the camshaft timing gear and tighten
the retaining bolt to the specified torque.
(12) Install the crankshaft timing gear spacer, key
and timing gear to the crankshaft. (13) Using a new crankshaft timing gear retaining
bolt, install the spacer and tighten the retaining bolt to
the specified torque. (14) Ensure that the oil pump pickup pipe and
screen are clean and free of foreign material. Install a
new O ring to the pipe and position the pickup pipe
and screen in position on the oil pump. Coat the
threads of the mounting bolts with Loctite 242 and
torque the bolts to the specified torque. (15) Fill a new oil filter with the correct grade of
engine oil and install the oil filter. (16) Install the sump as previously described.
(17) Install and adjust the camshaft drive belt as
described under the Camshaft Drive Belt heading. (18) Fill the engine with the correct grade and
quantity of oil. Refer to the Lubrication and Mainte-
nance section.
(19) Fill the cooling system as described in the
Cooling and Heating Systems section. (20) Start and run the engine and check for oil
and coolant leaks. (21) Install the engine splash guard to the
inner
right hand mudguard. (22) Install the right hand wheel and tighten the
wheel nuts as much as possible.

FUEL AND ENGINE MANAGEMENT
CAUTION: To prevent severe electrical shock, extreme care must be taken when
working on or near the electronic ignition system as dangerous high tension voltages
are produced in both the primary and secondary circuits. See the text fo\

TROUBLE SHOOTING

NOTE: The following Trouble Shooting pro-
cedures are basic checks only. If these pro-
cedures fail to locate the fault, refer to the
System Diagnosis and Adjustments heading
for more thorough testing.

Prior to performing any of the following
operations, refer to the Service Precautions
and Procedures heading.

ENGINE WILL NOT START OR HARD TO
START
(1) Water in the fuel: Dr ain the fuel from the
system and renew the fuel filter.
(2) Fault in the power supply: Check the battery,
fusible links and fuses. Check for clean, secure con-
nections, particularly the earth connections. Check the
EG1 and fuel pump relays.
NOTE: If the fuel pump relay fails, power
will be supplied to the fuel pump via the oil
pressure switch. When starting the engine,


Check that the MAP sensor hose is not blocked or split
and ensure that all electrical connections are clean and
secure.

Fuel and Engine Management 83
the fuel pump will not operate until the oil
pressure is sufficient to extinguish the oil
pressure warning lamp. Therefore it will be
necessary to operate the starter motor for a
longer period than usual to start the engine.

(3) Faulty EFI component wiring connections:
Check that all component wiring connections are
clean and secure.
(4) Manifold absolute pressure (MAP) sensor
vacuum hose blocked or disconnected: Clear or recon-
nect the vacuum hose. (5) Fault in the ignition system: Check the
primary and secondary ignition circuits.
(6) Engine flooded: Fully depress the throttle
pedal until the engine starts. Check the coolant
temperature sensor. Check th e injector(s) for leakage.
ENGINE STARTS THEN STALLS

(1) Water in the fuel: Dr ain the fuel from the
system and renew the fuel filter.
(2) Air leakage at the inlet manifold: Check all
joints and hoses for air leaks. (3) Faulty EFI wiring connections: Check that
all component wiring connections are clean and
secure.
(4) Ignition timing incorrectly set: Check and
adjust the timing. (5) MAP sensor faulty or supply hose discon-
nected or blocked: Check the vacuum supply hose.
Check the operation of the MAP sensor.
ENGINE MISFIRES

(1) Faulty, dirty or incorrectly adjusted spark
plugs: Renew or clean and adjust the spark plugs.
(2) Condensation in the distributor cap: Dry and
examine the cap for cracks. (3) Faulty high tension leads: Check and renew
the high tension leads.

Testing the fuel system pressure using a pressure
gauge.
(4) Faulty ignition coil: Check and renew the
ignition coil.
(5) Fuel blockage: Check for blockage in the fuel
filter, lines and injector(s). (6) Low fuel pressure: Check the fuel pump and
fuel pressure regulator. (7) Water in the fuel: Dr ain the fuel from the
system and renew the fuel filter. (8) Loose fuel supply wiring connectors: Check
all connectors for tightness. (9) Faulty fuel injector: Check the connections
and test the condition of the fuel injectors.
ENGINE LACKS POWER

(1) Ignition timing incorrectly set: Check and
adjust the timing.
(2) Water in the fuel: Dr ain the fuel from the
system and renew the fuel filter.
(3) Incorrectly adjusted throttle cable: Adjust the
throttle cable.



Check the distributor cap for cracks or tracking be- tween the terminals. The air filter element should be renewed at 40 000 km
intervals. 1.8 liter engine.
