block. Install distributor so distributor shaft engages with slot in
oil pump drive gear. It may be necessary to slightly rotate
distributor during installation.
6) When distributor is fully seated, the distributor rotor
should be at 3 o'clock position and center of hold-down bolt area on
distributor housing should align with distributor hold-down bolt area
on cylinder block.
7) Install hold-down clamp and distributor hold-down bolt.
Tighten distributor hold-down bolt to specification. See TORQUE
SPECIFICATIONS.
8) If installing a factory replacement distributor, remove
plastic alignment pin from distributor housing. If installing original
or used distributor, remove drift from distributor housing and
reinstall camshaft position sensor. On all applications, install
distributor cap and remaining components. Base ignition timing is
nonadjustable, as ignition timing and timing advance are controlled by
the Powertrain Control Module (PCM).
Removal (Dakota 3.9L, 5.2L & 5.9L, Durango, Ram Pickup 3.9L,
5.2L & 5.9L, Ram Van & Ram Wagon)
1) Disconnect negative battery cable. On Ram Van and Ram
Wagon, remove engine cover. On all models, remove air cleaner
assembly. Remove distributor cap. Disconnect electrical connector for
distributor.
2) Rotate crankshaft clockwise (viewed from front of engine)\
until cylinder No. 1 is at Top Dead Center (TDC) on compression stroke\
and timing mark on vibration damper aligns with TDC timing mark on
timing chain cover. Cylinder No. 1 is the front cylinder on driver's
side of engine.
3) Ensure distributor rotor aligns with cylinder No. 1
alignment mark on camshaft position sensor. See Fig. 23. If
distributor rotor is not properly aligned, rotate crankshaft clockwise
one full revolution. Ensure distributor rotor aligns with terminal for
cylinder No. 1 on distributor cap.
4) Scribe a mark on distributor and adjacent component to
indicate rotor and distributor housing position for installation
reference. Remove distributor hold-down bolt and hold-down clamp.

Installation
1) If engine has not been rotated after removing distributor,
go to next step. If engine was rotated after removing distributor,
rotate crankshaft clockwise (viewed from front of engine) until
cylinder No. 1 is at Top Dead Center (TDC) on compression stroke and
timing mark on vibration damper aligns with TDC timing mark on timing
chain cover. Go to next step.
2) Ensure distributor mounting area on cylinder block is
clean. Install NEW "O" ring on distributor if necessary. Apply light
coat of engine oil on "O" ring.
3) Position distributor rotor so it aligns with terminal for
cylinder No. 1 on distributor cap. Install distributor. Ensure
distributor engages with slot in oil pump drive gear. Install hold-
down clamp and distributor hold-down bolt. DO NOT tighten distributor
hold-down bolt at this time.
4) Rotate distributor until distributor rotor aligns with
cylinder No. 1 alignment mark on camshaft position sensor. See Fig. 23
. Tighten distributor hold-down bolt to specification. See TORQUE
SPECIFICATIONS. To install remaining components, reverse removal
procedure.
5) Base ignition timing is nonadjustable. Base ignition
timing and timing advance are controlled by the Powertrain Control
Module (PCM). Distributor position is used to determine the fuel
system synchronization. To check for correct distributor position and
fuel system synchronization, see FUEL SYSTEM SYNCHRONIZATION under
FUEL SYSTEM in ON-VEHICLE ADJUSTMENTS article.

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.

disconnect fitting snaps onto fuel tank fitting. Pull on small vent
tube or and large fill tube to ensure disconnect fitting is locked on
fuel tank fitting. To verify proper installation of disconnect
fitting, ensure the distance between release sleeve and top of fuel
tank fitting is .50" (12.7 mm) on small vent tube or .25" (6.4 mm) o\
n
large fill tube. See Fig. 37.
