INSTALLATION
(1) Before installation of the balance shaft assem-
bly, the # 1 cylinder must be brought to TDC. Using
special tool VM.1051, roll engine over by hand until
tool can be inserted into engine block locking fly-
wheel from turning (Fig. 88). Once the # 1 cylinder is
brought to TDC, the balance shaft assembly can be
installed.
(2) With balance shaft assembly on work bench.
Insert special tool VM.1056 into balance shaft assem-
bly (Fig. 89). This will ensure proper balance shaft
and crankshaft timing after assembly.

ACCELERATOR PEDAL
REMOVAL
(1) Hold the throttle body throttle lever in the
wide open position. Remove the throttle cable from
the throttle body cam.
(2) From inside the vehicle, hold up the pedal and
remove the cable retainer and throttle cable from the
upper end of the pedal shaft.
(3) Remove nuts from accelerator pedal attaching
studs. Remove assembly from vehicle.
INSTALLATION
(1) Position accelerator pedal assembly on dash
panel. Install retaining nuts. Tighten retaining nuts
to 12 N´m (105 in. lbs.) torque.
(2) From inside the vehicle, hold up the pedal and
install the throttle cable and cable retainer in the
upper end of the pedal shaft.
(3) From the engine compartment, hold the throt-
tle body lever in the wide open position and install
the throttle cable.
CRANKSHAFT POSITION
SENSOR
DESCRIPTION
The 2.4L crankshaft sensor is located on the rear
of the engine near the accessory drive belt (Fig. 1).
The 3.3/3.8L crankshaft sensor is located on the rear
of the transmission housing, above the differential
housing (Fig. 2). The bottom of the sensor is posi-
tioned next to the drive plate.
OPERATION
The crankshaft position sensor detects slots cut
into the transmission driveplate extension (Fig. 3).
There are 3 sets of slots. Each set contains 4 slots,
for a total of 12 slots (Fig. 4). Basic timing is set by
the position of the last slot in each group. Once the
Powertrain Control Module (PCM) senses the last
slot, it determines crankshaft position (which piston
will next be at TDC) from the camshaft position sen-
sor input. The 4 pulses generated by the crankshaft
position sensor represent the 69É, 49É, 29É, and 9É
BTDC marks. It may take the PCM one engine rev-
olution to determine crankshaft position.
The PCM uses crankshaft position reference to
determine injector sequence, ignition timing and the
presence of misfire. Once the PCM determines crank-
shaft position, it begins energizing the injectors in
sequence.
REMOVAL
(1) Disconnect the negative battery cable.
(2) Raise vehicle and support.
(3) Disconnect the electrical connector (Fig. 5).
(4) Remove crankshaft sensor bolt.
(5) Remove the crankshaft sensor.
REMOVAL - 3.3/3.8L
(1) Remove battery, refer to the Battery section for
more information.
(2) Remove the battery tray, refer to the Battery
section for more information.

FUEL TRANSFER PUMP
DESCRIPTION
The fuel transfer pump (fuel lift pump) is located
under the vehicle in front of the rear axle assembly
(Fig. 5). The 12±volt electric vane-type pump is oper-
ated and controlled by the Engine Control Module
(ECM) .
OPERATION
The purpose of the fuel transfer pump is to supply
(transfer) a low-pressure fuel source:fromthe fuel
tank,throughthe fuel filter/water separator andto
the fuel injection pump. Here, the low-pressure is
raised to a high-pressure by the fuel injection pump
for operation of the high-pressure fuel injectors.The fuel transfer pump is controlled by the Engine
Control Module(ECM). The ECM turns the fuel
transfer pump on for 30 seconds when the ignition
ket is turned ªONº.
With the ignition ªONº and fuel tranfer pump run-
ning, the low-pressure fuel pressure should be 13-17 psi.
FUEL INJECTION PUMP
DESCRIPTION
A radial-piston pump is used as the high pressure
pump for fuel pressure generation (Fig. 6).
REMOVAL
(1) Disconnect negative battery cable.
(2) Remove engine cover (Refer to 9 - ENGINE -
REMOVAL)
(3) Remove air cleaner housing assembly.
(4) Remove power steering belt (Refer to 7 -
COOLING/ACCESSORY DRIVE/DRIVE BELTS -
REMOVAL).
(5) Remove accessory drive belt (Refer to 7 -
COOLING/ACCESSORY DRIVE/DRIVE BELTS -
REMOVAL).
(6) Support engine and remove right engine mount
assembly.
(7) Remove outer timing belt cover (Refer to 9 -
ENGINE/VALVE TIMING/TIMING BELT / CHAIN
COVER(S) - REMOVAL).
(8) Using special tool VM.1055, remove injection
pump sprocket retaining nut (Fig. 7).

NOTE: The use of special tool VM.1067 will allow
you to remove the injection pump without removing
the timing belt from the engine. This will allow you
to remove and install the injection pump without
altering injection pump timing.
(9) Install feet from VM.1067 in injection pump
sprocket as shown (Fig. 8).
(10) Install inner flange of special tool VM.1067 on
injection pump sprocket as shown (Fig. 9). Secure
flange to feet in injection pump sprocket with allen
bolts supplied with tool.
(11) Screw injection pump sprocket holding plate
assembly into flange of VM.1067 (Fig. 10) Using LHD
threaded bolt supplied, secure holding plate assembly
to timing belt inner cover.(12) Remove generator (Fig. 11). (Refer to 8 -
ELECTRICAL/CHARGING/GENERATOR -
REMOVAL)
(13) Disconnect fuel supply and return lines at
injection pump (Fig. 11)
(14) Disconnect fuel pressure solenoid electrical
connector at injection pump (Fig. 11)
(15) Remove injection pump retaining nuts.
(16) While holding injection pump, tighten bolt in
center of injection pump holding plate (Fig. 10).This
will push the injection pump out of the injection
pump sprocket.
