CRANKSHAFT POSITION SENSOR (CKP)
NOTE: Crankshaft Position (CKP) sensor may be referred to as engine\
speed sensor.
Removal & Installation
1) CKP sensor is located on left rear side of engine block

FUEL LINE BLEEDING
NOTE: Fuel line bleeding is necessary if fuel injection pump is
replaced, fuel filter/water separator is not filled with
diesel fuel before installing or vehicle ran out off fuel.
Bleed high-pressure fuel lines if connections are loosened or
replaced. If engine has not been operated for an extended
time, bleed fuel lines before next initial engine start-up.
WARNING: DO NOT bleed fuel lines on a hot engine, as high exhaust
temperatures may cause a fire. Carefully bleed fuel lines, as
fuel is under extremely high pressure and could penetrate
skin. Use safety goggles and protective clothing when
bleeding fuel lines.
1) Loosen banjo bolt holding low-pressure fuel supply line to
side of fuel injection pump. Wrap a towel around banjo fitting to
catch fuel. Crank engine quickly and release key before engine starts.
This will operate fuel transfer pump for about 25 seconds.
2) If fuel is not present at fuel supply line after 25
seconds, turn ignition off. Repeat engine crank procedure until fuel
is present at fuel supply line. Tighten banjo bolt at fuel supply line
to specification. See TORQUE SPECIFICATIONS.
CAUTION: Ensure parking brake is applied and transmission is in
Neutral before bleeding fuel injection pump or high-pressure
fuel lines. DO NOT operate starter for more than 30 seconds
when bleeding fuel injection pump or high-pressure fuel
lines. Allow 2-minute intervals between starter operations.
3) To bleed air from fuel injection pump, ensure parking
brake is applied and transmission is in Neutral, as engine may start
when operating starter to bleed air from fuel injection pump. Operate
starter for 30 seconds to bleed any trapped air in fuel injection
pump.
4) To bleed high-pressure fuel lines, ensure parking brake is
applied and transmission is in Neutral, as engine may start when
operating starter to bleed high-pressure fuel lines. Loosen high-
pressure fuel line nut at fuel injector.
5) Operate starter until steady fuel flow exists at high-
pressure fuel line. Tighten high-pressure fuel line nut to
specification. See TORQUE SPECIFICATIONS. Start engine. Repeat
procedure on each high-pressure fuel line until engine operates
smoothly.
FUEL FILTER/WATER SEPARATOR & WATER-IN-FUEL SENSOR
NOTE: Vehicle also contains an in-tank fuel filter located on
bottom of fuel tank module. For servicing procedure, see FUEL
TANK MODULE & IN-TANK FUEL FILTER under FUEL SYSTEM.
NOTE: When fuel filter/water separator is being replaced,
manufacturer recommends cleaning the pre-filter. See FUEL
HEATER under FUEL SYSTEM for servicing of pre-filter.
Removal
1) Ensure engine is off. Place drain pan below drain tube at
fuel filter/water separator. See Fig. 3. Rotate handle on drain valve
forward, toward front of vehicle to DRAIN position. Drain valve is
located near top of fuel filter/water separator. See Fig. 3. Once fuel
is drained from fuel filter/water separator, rotate handle on drain
valve back to CLOSE position.

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.
