line to eliminate danger.
WITH CONSULT-IINEEC0024S011. Start engine.
2. Perform ªFUEL PRESSURE RELEASEº in ªWORK SUP-
PORTº mode with CONSULT-II.
3. After engine stalls, crank it two or three times to release all fuel
pressure.
4. Turn ignition switch OFF.
SEC306D
WITHOUT CONSULT-IINEEC0024S021. Remove fuse for fuel pump.

Fuel Pressure CheckNEEC0025+When reconnecting fuel line, always use new clamps.
+Make sure that clamp screw does not contact adjacent
parts.
+Use a torque driver to tighten clamps.
+Use Pressure Gauge to check fuel pressure.
+Do not perform fuel pressure check with system operat-
ing. Fuel pressure gauge may indicate false readings.
1. Release fuel pressure to zero.
2. Disconnect fuel hose between fuel filter and fuel tube (engine
side).
3. Install pressure gauge between fuel filter and fuel tube.
4. Start engine and check for fuel leakage.
5. Read the indication of fuel pressure gauge.

Parts Requiring Angular Tightening
+Use an angle wrench for the final tightening of the following
engine parts:
a) Cylinder head bolts
b) Main bearing cap bolts (YD series)
c) Connecting rod cap nuts (KA and YD series)
d) Crankshaft pulley bolt (YD series)
+Do not use a torque value for final tightening.
+The torque value for these parts are for a preliminary step.
+Ensure thread and seat surfaces are clean and coated with
engine oil.
Liquid Gasket Application Procedure
1.Use a scraper to remove all traces of old liquid gasket
from mating surfaces and grooves. Also, completely
clean any oil from these areas.
2.Apply a continuous bead of liquid gasket to mating sur-
faces. (Use Genuine Liquid Gasket or equivalent.)
+Be sure liquid gasket diameter is as specified in this manual.
3.Apply liquid gasket around the inner side of bolt holes
(unless otherwise specified).
4.Assembly should be done within 5 minutes after coating.
5.Wait at least 30 minutes before refilling engine oil and
engine coolant.

FUEL PIPING
Removal
+To prevent fuel from flowing out, plug the opening of the hose
with a blind plug after disconnection.
+Be careful not to spill fuel in the engine compartment.
Installation
After repairing, bleed air in pipes by shifting priming pump up and
down until the touch is heavy.
For further air bleeding, crank engine while operating priming
pump up and down. Do not crank engine more than 10 seconds
at a time.
INTAKE MANIFOLD
Removal
+Loosen bolts and nuts in the reverse order of that shown in
the figure.
Installation
+When stud bolts come off, install with the following torque:
:10-11Nzm (1.0 - 1.2 kg-m, 87 - 104 in-lb)
+Tighten fixing bolts in the numerical order shown in the fig-
ure.
EGR VOLUME CONTROL VALVE
+Handle with care avoiding any shocks.
+Do not disassemble or adjust.
