All models are fitted with a rear-mounted fuel
tank. Fuel is conveyed from the tank by a
mechanical or electrical fuel pump, according tomodel and equipment, to the carburettor or fuel-
injection system. The delivery capacity of the
fuel pump exceeds the maximum demands of
the system, so excess fuel is constantly returned
to the tank. This helps to avoid the problems of
vapour locks in the fuel lines.
Carburettor models have a twin venturidowndraught carburettor of Pierburg
manufacture on 1.8 litre models and Weber on
2.0 litre models. Both makes of carburettor
have an automatic choke.
Fuel-injection, when fitted, is of the Bosch
L-Jetronic type. This system is under the
control of the EEC IV module.

6Disconnect the cable inner from the throttle
lever on the carburettor or fuel-injection linkage.
The cable may be secured by a spring clip, or by
a simple barrel and slot arrangement (see
illustration).
7Disconnect the cable outer from its bracket.
It may be secured by a spring clip, or by four
plastic lugs. The lugs are most easily released
with a tool (see illustration).
8Refit by reversing the removal operations.
Adjust the threaded sleeve on the cable outer
so that there is a small amount of slack with
the pedal released; have an assistant operate
the throttle pedal and check that the throttle
lever moves over its full range of travel.
9On automatic transmission models, check
the adjustment of the kickdown cable.
1All carburettor models are fitted with a
vapour separator, mounted on the left-hand
inner wing. On 1.8 litre models the separator
incorporates a pressure regulator (see
illustrations).2Disconnect the battery negative lead.
3Identify the three hoses connected to the
separator. Disconnect the hoses, cutting off
the hose clips if they are of the crimped type.
4Remove the two securing screws and lift out
the separator. Remember it is full of fuel.
5Refit by reversing the removal operations.
Make sure that the different hoses are
connected to the correct stubs on the
regulator. Use new hose clips when
necessary.

and withdraw the solenoid from the location.
6Refitting is a reversal of removal, ensuring
that the solenoid pipes are correctly
reconnected, and that the solenoid is correctly
orientated as noted before removal.
SOHC and 2.8 litre V6 engines
1It is generally believed that continuous use
of unleaded fuel can cause rapid wear of
conventional valve seats. Valve seat inserts
which can tolerate unleaded fuel are fitted to
some engines. These engines are identified as
follows:
1.8 litre - S stamped adjacent to No 4 spark
plug
2.0 litre - A, L, P, PP or R stamped adjacent
to No 4 spark plug
2.8 litre - D or E stamped in centre of
cylinder head exhaust flange
2Engines which are marked as above can be
run entirely on unleaded fuel.
3Engines which are not fitted with the specialvalve seat inserts can still be run on unleaded
fuel, but one tankful of leaded fuel should be
used for every three tankfuls of unleaded. This
will protect the valve seats.
4On all models, the ignition timing may have
to be retarded when unleaded fuel is used. For
up to date information consult a Ford dealer.
DOHC engines
5All models can be operated on unleaded
petrol without the need for any adjustments.
Note that models fitted with a catalytic
converter must only be operated on unleaded
petrol, and leaded petrol must notbe used.
2.4 & 2.9 litre V6 engines
6All engines can be run on 95 octane
unleaded fuel (ie Premium grade unleaded).
7On 2.9 litre models equipped with a manual
gearbox produced after approximately
December 1988 and models equipped with
automatic transmission which were produced
after approximately July 1988, there is no
need to adjust the ignition timing to run on
unleaded petrol. These models can be
identified by their ignition module number
suffixes; on manual gearbox models the
module should have a JA suffix and on models
equipped with automatic transmission the
module should have a BD suffix. Refer to your
Ford dealer for further information.
8On all other earlier models, the ignition
timing must be adjusted before the engine can
be run on unleaded petrol. On these models
the timing must be adjusted by the fitment of
an octane adjustment lead, described in
Chapter 5, Section 23. On both the 2.4 & 2.9
litre engines, the lead should be fitted and the
red terminal earthed; this retards the ignition
timing by 4°from the initial setting of 12°
BTDC, to the correct setting of 8°BTDC.
9Models which are equipped with a catalytic
converter must be run on unleaded fuel only.

engine coolant temperature sensor. The
crankshaft speed/position sensor is activated
by a toothed disc on the rear of the crankshaft,
inside the cylinder block. The disc has 35
equally spaced teeth (one every 10°), with a
gap in the 36th position. The gap is used by
the sensor to determine the crankshaft
position relative to Top Dead Centre (TDC) of
No 1 piston.
The ignition advance is a function of the
ESC II module, and is controlled by vacuum.
The module is connected to the carburettor by
a vacuum pipe, and a transducer in the
module translates the vacuum signal into an
electrical voltage. From the vacuum signal, the
module determines engine load; engine speed
and temperature are determined from the
crankshaft speed/position sensor and the
engine coolant temperature sensor. The
module has a range of spark advance settings
stored in the memory, and a suitable setting is
selected for the relevant engine speed, load
and temperature. The degree of advance can
thus be constantly varied to suit the prevailing
engine speed and load conditions.
On DOHC fuel-injected engines, a
development of the EEC IV (Electronic Engine
Control IV) engine management system is
used to control both the ignition and fuel-
injection systems. The EEC IV module receives
information from a crankshaft speed/position
sensor (the same as that fitted to the
carburettor models), a throttle position sensor,
an engine coolant temperature sensor, a fuel
temperature sensor, an air charge temperature
sensor, a Manifold Absolute Pressure (MAP)
sensor, and a vehicle speed sensor (mounted
on the gearbox). Additionally, on models with
a catalytic converter, an additional input is
supplied to the EEC IV module from an
exhaust gas oxygen (HEGO) sensor. On
models with automatic transmission,
additional sensors are fitted to the
transmission to inform the EEC IV module
when the transmission is in neutral, and when
the downshift is being operated.
The module provides outputs to control the
fuel pump, fuel-injectors, idle speed, ignition
system and automatic transmission .
Additionally, on models with air conditioning,
the EEC IV module disengages the air
conditioning compressor clutch when starting
the engine or when the engine is suddenly
accelerated. On models fitted with a catalytic
converter, the EEC IV module also controls the
carbon canister purge solenoid valve.
Using the inputs from the various sensors,
the EEC IV module computes the optimum
ignition advance, and fuel-injector pulse
duration to suit the prevailing engine
conditions.
On 2.4 & 2.9 litre V6 engines, the system
operates in much the same way as that fitted
to the DOHC fuel-injected engine, noting the
following points.
a)There is no crankshaft speed/position
sensor.
b)The vehicle speed sensor is only fitted to
models equipped with a catalytic
converter.Precautions
ESC II module
Although it will tolerate all normal under-
bonnet conditions, the ESC II module may be
adversely affected by water entry during
steam cleaning or pressure washing of the
engine bay.
If cleaning the engine bay, therefore, take
care not to direct jets of water or steam at the
ESC II module. If this cannot be avoided,
remove the module completely, and protect its
multi-plug with a plastic bag.
Ignition system HT voltage
Take care to avoid receiving electric shocks
from the HT side of the ignition system. Do not
handle HT leads, or touch the distributor or
coil, when the engine is running. When tracing
faults in the HT system, use well insulated
tools to manipulate live leads. Electronic
ignition HT voltage could prove fatal.
Electronic ignition systems
General
Further details of the various systems are
given in the relevant Sections of this Chapter.
While some repair procedures are given, the
usual course of action is to renew the
component concerned. The owner whose
interest extends beyond mere component
renewal should obtain a copy of the
Automobile Electrical & Electronic Systems
Manual, available from the publishers of this
manual.
It is necessary to take extra care when
working on the electrical system, to avoid
damage to semi-conductor devices (diodes
and transistors), and to avoid the risk of
personal injury. In addition to the precautions
given in Safety first!at the beginning of this
manual, observe the following when working
on the system:
Always remove rings, watches, etc before
working on the electrical system.Even with the
battery disconnected, capacitive discharge
could occur if a component’s live terminal is
earthed through a metal object. This could
cause a shock or nasty burn.
Do not reverse the battery connections.
Components such as the alternator, electronic
control units, or any other components having
semi-conductor circuitry, could be irreparably
damaged.
If the engine is being started using jump
leads and a slave battery, connect thebatteries positive-to-positiveand negative-to-
negative(see “Jump starting”). This also
applies when connecting a battery charger.
Never disconnect the battery terminals, the
alternator, any electrical wiring, or any test
instruments, when the engine is running.
Do not allow the engine to turn the alternator
when the alternator is not connected.
Never test for alternator output by “flashing”
the output lead to earth.
Never use an ohmmeter of the type
incorporating a hand-cranked generator for
circuit or continuity testing.
Always ensure that the battery negative lead
is disconnected when working on the
electrical system.
Before using electric-arc welding equipment
on the car, disconnect the battery, alternator,
and components such as the fuel-
injection/ignition electronic control unit, to
protect them from the risk of damage.
Refer to Chapter 13
1In normal use the battery should not require
charging from an external source, unless the
vehicle is laid up for long periods, when it
should be recharged every six weeks or so. If
vehicle use consists entirely of short runs in
darkness it is also possible for the battery to
become discharged. Otherwise, a regular
need for recharging points to a fault in the
battery or elsewhere in the charging system.
2There is no need to disconnect the battery
from the vehicle wiring when using a battery
charger, but switch off the ignition and leave
the bonnet open.
3Domestic battery chargers (up to about 6
amps output) may safely be used overnight
without special precautions. Make sure that
the charger is set to deliver 12 volts before
connecting it. Connect the leads (red or
positive to the positive terminal, black or
negative to the negative terminal) before
switching the charger on at the mains.
4When charging is complete, switch off at
the mains beforedisconnecting the charger
from the battery. Remember that the battery
will be giving off hydrogen gas, which is
potentially explosive.
5Charging at a higher rate should only be
carried out under carefully controlled
conditions. Very rapid or “boost” charging
should be avoided if possible, as it is liable to
cause permanent damage to the battery
through overheating.
6During any sort of charging, battery
electrolyte temperature should never exceed
38°C (100°F). If the battery becomes hot, or
the electrolyte is effervescing vigorously,
charging should be stopped.

Warning. The voltages produced
by the electronic ignition system
are considerably higher than those
produced by conventional
systems. Extreme care must be taken when
working on the system with the ignition
switched on. Persons with surgically-
implanted cardiac pacemaker devices
should keep well clear of the ignition
circuits, components and test equipment.

16Undo the wiring connector retaining bolt
then carefully disconnect the wiring plug and
remove the module from the car (see
illustration).
17Refitting is a reverse of the removal
procedure ensuring that the wiring plug bolt is
securely tightened. On completion start the
engine and check that it runs correctly.
Note: Irregular idle is not necessarily caused
by a faulty or badly adjusted stepper motor.
Good electrical contact between the stepper
motor plunger and the adjusting screw is
essential. Before attempting adjustment or
renewal of the motor, try the effect of cleaning
the plunger and adjusting screw contact faces
with abrasive paper followed by switch
cleaning fluid. Switch cleaning fluid is available
from electronic component shops.
1Disconnect the battery negative lead.
2Remove the air cleaner.
3Disconnect the multi-plug from the stepper
motor. Release the locking clip and pull on the
plug, not on the wires.
4Remove the four screws which secure the
stepper motor bracket to the carburettor.Remove the motor and bracket and separate
them (see illustration).
5Refit the motor and bracket to the
carburettor and secure with the four screws.
Reconnect the multi-plug.
6Make an initial adjustment to the throttle
lever adjusting screw if necessary so that it
protrudes from the lever by dimension X (see
illustration).
7Reconnect the air cleaner vacuum hose.
Position the air cleaner to one side so that
there is still access to the carburettor and
stepper motor.
8Connect a tachometer (rev. counter) to the
engine as instructed by the manufacturers.
Reconnect the battery.
9Run the engine. Check the idle mixture (CO
level) as described in Chapter 4 and adjust if
necessary.
10Switch off all electrical loads (headlights,
heater blower etc). If the idle speed adjustment
lead is earthed, temporarily isolate it. Make
sure that the automatic transmission selector is
in the N or P position (where applicable).
11Accelerate the engine to a speed greater
then 2500 rpm, allow it to return to idle, then
repeat. Insert a feeler blade of thickness 1.0
mm (0.04 in) between the stepper motor
plunger and the adjusting screw(see
illustration).With the feeler blade in place,
engine speed should be 875 ±25 rpm. 12If adjustment is necessary, remove the
tamperproof cap from the adjusting screw
locknut. Release the locknut, turn the
adjusting screw to achieve the correct speed
and tighten the locknut.
13Repeat paragraph 11 and check that the
speed is still correct. Readjust if necessary.
14Remove the feeler blade. Stop and restart
the engine, observing the stepper motor
plunger. Immediately after switching off, the
plunger should move to the “anti-dieseling”
position; after a few seconds it should extend
to the “vent manifold/start” position (see
illustration).
15Disconnect the test gear and refit the air
cleaner.
16Recheck the idle mixture.
17Fit new tamperproof plugs or caps if
necessary - see Chapter 4,
18Reconnect the idle speed adjustment lead
if it was earthed.
1The engine management system
temperature sensor is located on the underside
of the inlet manifold (SOHC engines), the side
of the manifold (DOHC engines) or on the front
face of the cylinder block (V6 engines).
