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.

have been completed. Disconnect all test equipment. Install ASD relay.
On 5.9L diesel engines, reconnect fuel shutdown relay connector. On
all models, start engine several times to verify malfunction has been
corrected.
CRANKING TEST
NOTE: Ensure engine is at normal operating temperature. High
viscosity oil, extreme cold temperatures, or tight engine
will increase amperage draw.
1) Using a battery load tester, connect positive and negative
leads to battery. Connect inductive ammeter pick-up to positive
battery cable. Disable ignition and fuel systems. See
DISABLING/ENABLING IGNITION & FUEL SYSTEMS.
2) Ensure all lights and accessories are off. Place A/T in
Park position or M/T in Neutral position. Apply parking brake. Crank
engine and observe voltmeter reading. If voltage is more than 9.6
volts and cranking amperage draw is more than specified amps, proceed
to CIRCUIT RESISTANCE TESTS. See STARTER SPECIFICATIONS - CARS or
STARTER SPECIFICATIONS - TRUCKS.
3) If voltage is 12.5 volts or more and cranking amperage
draw is less than specified, check starter circuit components in the
following order:
starter solenoid, starter relay, starter relay circuit, park/neutral
position switch or transmission range sensor (A/T), clutch pedal
position switch (M/T), ignition switch, wiring harness and
connections.
CIRCUIT RESISTANCE TESTS
NOTE: If excessive resistance is not found in circuits being
tested, remove starter and proceed to BENCH TESTING.
Battery Connection Resistance Test
1) Disable vehicle ignition and fuel systems. See
DISABLING/ENABLING IGNITION & FUEL SYSTEMS. A voltmeter accurate to
one tenth of a volt will be needed for the following tests.
