pulley for the accessory drive belt, as these bolts are under
tension. If necessary to remove these bolts, accessory drive
belt must be removed first.
2) Remove ignition coil retaining bolts or nuts with ignition
coil from the ignition coil mounting bracket. On 3.9L, 5.2L and 5.9L
with light-duty emissions, DO NOT remove ignition coil-to-cylinder
head mounting bracket bolts, as these bolts are under tension. On all
applications, to install, reverse removal procedure. Tighten ignition
coil retaining bolts or nuts to specification. See TORQUE
SPECIFICATIONS.
Removal & Installation (Ram Pickup 8.0L)
1) Two separate ignition coils are located above passenger's
side valve cover. Each ignition coil can be serviced separately. On
all ignition coil applications, disconnect spark plug wires and
electrical connector from ignition coil.
2) Remove ignition coil retaining bolts and ignition coil
from ignition coil mounting bracket. To install, reverse removal
procedure. Ensure ignition coil is mounted on ignition coil mounting
bracket with electrical connector facing downward. Tighten ignition
coil retaining bolts to specification. See TORQUE SPECIFICATIONS.
FUEL SYSTEM
FUEL SYSTEM PRESSURE RELEASE
WARNING: Always release fuel pressure before disconnecting any fuel
injection-related component. DO NOT allow fuel to contact
engine or electrical components.
1) Remove fuel cap from fuel tank. Note location of spring
loaded flapper valve inside fuel tank filler tube assembly. Flapper
valve is located just below the fuel cap area on fuel tank filler tube
assembly. Flapper valve is used as a secondary way of sealing the fuel
tank if fuel cap was not properly tightened.
WARNING: When opening flapper valve inside fuel tank filler tube
assembly, ensure a non-metallic object is used to prevent any
sparks.
2) Using a non-metallic object, push flapper valve inside
filler tube assembly downward to release any pressure from the fuel
tank. Ensure all pressure is released from fuel tank.
3) Remove fuel pump relay from Power Distribution Center
(PDC). Fuel pump relay may be identified by label on inside of PDC
cover. See POWER DISTRIBUTION CENTER (PDC) LOCATION table.
4) On all models, start engine and allow engine to idle until
engine stalls. Attempt to restart engine until engine will no longer
run. Turn ignition off.
CAUTION: Ensure steps 1) through 4) are performed before proceeding.
Steps 3) and 4) must be performed to ensure most of the fuel
pressure is released from fuel rails to prevent an excessive
amount of fuel being delivered into the cylinders.
5) Remaining fuel pressure is released by energizing a fuel
injector. Disconnect electrical connector at any fuel injector.
6) Connect jumper wire between one electrical terminal on
fuel injector and positive battery terminal. Connect another jumper
wire on remaining electrical terminal on fuel injector.

1) Fuel filter/fuel pressure regulator is mounted in rubber
grommet on top of fuel pump module. See Figs. 27-30. Fuel pump module
is located on top of fuel tank.
2) Manufacturer recommends removing fuel tank for access to
fuel filter/fuel pressure regulator. See FUEL TANK. Ensure area around
fuel filter/fuel pressure regulator and fuel pump module is clean.
CAUTION: When removing fuel filter/fuel pressure regulator from fuel
tank, DO NOT pull fuel filter/fuel pressure regulator more
than 3.0" (76 mm) from fuel tank or plastic fuel line
attached to fuel filter/fuel pressure regulator may be
damaged.
3) Using twisting motion, pull fuel filter/fuel pressure
regulator from rubber grommet on fuel pump module. Ensure fuel
filter/fuel pressure regulator is not pulled more than 3.0" (76 mm)
from fuel tank or plastic fuel line attached to fuel filter/fuel
pressure regulator may be damaged.
4) Carefully cut plastic fuel line-to-fuel filter/fuel
pressure regulator retaining clamp. Use care not to damage plastic
fuel line. Remove retaining clamp. Remove plastic fuel line from fuel
filter/fuel pressure regulator.
Installation
1) Install plastic fuel line with NEW retaining clamp on fuel
filter/fuel pressure regulator. Rotate fuel filter/fuel pressure
regulator in plastic fuel line until fuel line fitting on side fuel
filter/fuel pressure regulator points proper direction. See
POSITIONING FUEL FILTER/FUEL PRESSURE REGULATOR table.

CAUTION: Ensure Crimping Pliers (C-4124) are used to crimp retaining
clamp for plastic fuel line. DO NOT use conventional side
cutters to crimp retaining clamp.
2) Using Crimping Pliers (C-4124), crimp retaining clamp for\
plastic fuel line. Ensure plastic fuel line is securely attached on
fuel filter/fuel pressure regulator.
3) To install remaining components, reverse removal
procedure. Ensure fuel filter/pressure regulator is installed in
rubber grommet on fuel pump module so fuel line fitting on side fuel
filter/fuel pressure regulator points toward proper direction before
installing fuel tank. See POSITIONING FUEL FILTER/FUEL PRESSURE
REGULATOR table. Reinstall fuel tank using proper procedure.

NOTE: Fuel level sensor may also be referred to as fuel gauge
sending unit.

Fig. 31 . Fuel pump module is located on top of fuel tank. See Figs. 27
-30.
2) Remove fuel pump module. See FUEL PUMP MODULE under FUEL
SYSTEM. Disconnect electrical connector for fuel pump and fuel level
sensor from electrical connector from bottom side of electrical
connector mounted on top of fuel pump module. See Fig. 31.
3) Remove locking collar from electrical connector for fuel
pump and fuel level sensor. Locking collar must be removed so wires
for fuel level sensor may be removed from the electrical connector for
fuel pump and fuel level sensor.
CAUTION: Note location of wires in electrical connector for fuel pump
and fuel level sensor for installation reference. Wires must
be installed in correct location.
4) Mark wire location in electrical connector for fuel pump
and fuel level sensor for installation reference. Remove wires for
fuel level sensor from electrical connector for fuel pump and fuel
level sensor.
5) Note location of notch and locking tab at end of fuel
level sensor. See Fig. 31. Carefully push locking tab away from notch
while sliding fuel level sensor down the channels, toward bottom of
fuel pump module. Note wire routing when removing fuel level sensor
from fuel pump module. Remove fuel level sensor.
Installation
1) Install fuel level sensor on channels of fuel pump module.
Ensure wires are properly routed. Slide fuel level sensor onto fuel
pump module until fuel level sensor snaps into place. Ensure locking
tab is fully seated.
2) Install wires for fuel level sensor in electrical
connector for fuel pump and fuel level sensor. Install locking collar.
Install electrical connector for fuel pump and fuel level sensor on
electrical connector on bottom side of electrical connector mounted on
top of fuel pump module. Reinstall fuel pump module. To complete
installation, reverse removal procedure.
