12 Extract the retaining clips and pull the
injectors out of the fuel rail (see illustration).
13 The sealing rings and retaining clips on all
injectors must be renewed, even if only one
injector has been removed from the rail. The
lower seal fits between the thick and thin
washers at the tip of the injector (see
illustration).
14 Commence refitting by coating the injector
sealing rings with silicone grease to Ford spec
ESEM 1C171A.
15 Press the injectors into the fuel rail and
secure them with the new retaining clips.
Press the clips home.
16 Reconnect the multi-plugs to the injectors.
17 Place the assembled fuel rail on the inlet
manifold and press the injectors into their
holes.
18 On V6 models, fit and tighten the fuel rail
bolts. Refit the plenum chamber, using new
gaskets, and tighten the bolts to the specified
torque. Reconnect the throttle cable(s).
19 On OHC models, fit the fuel rail bolts but
do not tighten them yet.
20 On all models, reconnect the fuel and
vacuum pipes. Tighten the fuel pipe unions.
21 On OHC models, tighten the fuel rail bolts
to the specified torque.
22 Reconnect the multi-plugs which were
displaced during removal. On V6 models,
secure the HT leads to the pressure regulator
bracket.
23 On OHC models, refit the distributor cap.
24 Refit the air inlet trunking.
25 On V6 models, refit the throttle linkage
cover.
26 Reconnect the battery. Run the engine
and check that there are no fuel leaks.
27 Check the exhaust CO level.
DOHC engine
28 Disconnect the battery negative lead.
29 If desired, to improve access, disconnect
the wiring from the inlet air temperature sensor
in the inlet manifold. Similarly, the throttle
cable can be moved to one side by
disconnecting the cable from the throttle
linkage and the spark plug HT leads can be
disconnected and moved to one side, noting
their locations and routing to aid refitting.
30 Slowly loosen the fuel rail fuel feed union
to relieve the pressure in the system. Be
prepared for fuel spillage, and take adequate
fire precautions.
31 Disconnect the fuel feed hose from the
fuel rail (see illustration).
32 Disconnect the fuel return hose from the
fuel pressure regulator. Again, be prepared for
fuel spillage.
33 Disconnect the vacuum pipe from the top
of the fuel pressure regulator.
34 Disconnect the wiring plugs from the fuel
temperature sensor and the fuel-injectors,
noting their locations to assist with refitting.
35 Unscrew the two securing bolts, and
withdraw the fuel rail.
36 Lift the fuel-injectors from their locations in
the cylinder head (see illustration).
37 Overhaul of the fuel-injectors is not
possible, as no spares are available. If faulty,
an injector must be renewed.
38 Commence refitting by fitting new seals to
both ends of each fuel-injector. It is advisable
to fit new seals to all the injectors, even if only
one has been removed. Lubricate the seals
with clean engine oil.
39 Further refitting is a reversal of removal,
ensuring that all hoses, pipes and wiring plugs
are correctly connected.
40 On completion, where applicable, check
and if necessary adjust the idle mixture.
2.4 & 2.9 litre V6 engines
41 Disconnect the battery.
42 Remove the air inlet pipes from the throttle
housing.
43 Disconnect the link arm from the throttle
housing and unscrew the two bolts which
retain the throttle cable bracket.
44 Disconnect the vacuum pipes from the
throttle housing, crankcase vent valve and the
fuel pressure regulator.
45 Disconnect the wiring connectors from the
throttle position sensor, engine and coolant
temperature sensors and the idle speed
control valve.
46 Extract the six Torx bolts which hold the
air inlet chamber in position.
47 Carefully disconnect the fuel-injector
wiring connectors (see illustration).
48 Depressurise the fuel system.
49 Disconnect the fuel rail feed pipe and the
fuel return pipe. This is best done at the wing
valance and will require cutting the crimped
hose clips.
50 The crimped-type clips must then be
replaced with standard worm drive hose clips
on refitting.
51 Unscrew the fuel rail retaining bolts and
remove the fuel rail.
52 Extract the retaining clips and remove the
injectors from the fuel rail.
53 Refitting is a reverse of the removal
procedure bearing in mind the following.
54 Renew all the upper and lower injector
seals, even if only one injector has been
disturbed. Lubricate all new seals with clean
engine oil.
55 On models fitted with an early level fuel
pressure regulator, it is necessary to fit a new
fuel inlet pipe to the fuel rail, the new
