ENGINE MECHANICAL
Before performing any on-vehicle adjustments to fuel system,
ensure engine mechanical condition is okay.
VALVE CLEARANCE
NOTE: Valve clearance must be adjusted with engine temperature less
than 140F (60C).
1) Disconnect negative battery cables. Remove valve cover.
Remove fuel pump gear access cover, located at front of engine. Using
Engine Barring Tool (7471B), rotate engine to align pump gear mark
with TDC mark on gear housing cover. See Fig. 1.

2) With cylinder No. 1 at TDC, check valve clearance on
proper valves. Perform STEP 1. See Fig. 2. See VALVE CLEARANCE

ADJUSTING SEQUENCE table. Using feeler gauge, check valve clearance
between rocker arm socket and crosshead. Ensure valve clearance is
within specification. See VALVE CLEARANCE SPECIFICATIONS table. If
valve clearance is within specification, go to next step. If any valve
clearance is not within specification, loosen rocker lever adjusting
screw lock nut, and adjust valve clearance by rotating rocker lever
adjusting screw. Tighten rocker lever adjusting screw lock nut to
specification. See TORQUE SPECIFICATIONS. When all valve clearances
are within specification, go to next step.

4) Install valve cover, fuel pump access cover and battery
cables.
FUEL INJECTION PUMP TIMING
CHECKING FUEL INJECTION PUMP TIMING
NOTE: With Bosch VP 44 pump, no mechanical adjustments are
necessary. All timing and fuel adjustments are performed by
Engine Control Module (ECM). If a FTC indicating engine sync
error or static timing error has been set, perform following
adjustment. If FTC sets after installing a new pump, pump
keyway has probably been installed backward.
CAUTION: DO NOT allow nut and washer to fall inside front cover.
1) Remove fuel pump access cover, shaft nut and washer.
Ensure keyway aligning pump shaft to pump gear has not slipped. If
keyway has slipped, repair as necessary.
2) Remove timing gear cover. See REMOVAL, OVERHAUL &
INSTALLATION - TRUCKS - DIESEL article. Using a T-type puller, remove
injection pump gear from shaft. Ensure key has been installed in
keyway with arrow pointing to rear of pump. Pump timing is calibrated
to pump keyway. Ensure 3-digit number on key matches number on pump

data plate. See Fig. 3. There are 21 different calibrations available.
Repair as necessary.

crankshaft gear, camshaft gear and fuel pump gear are aligned. See

CHRY - Basic Diagnostic Procedures - Trucks - Diesel

INTRODUCTION
The following diagnostic steps will help prevent overlooking
a simple problem. This is also where to begin diagnosis for a no-start
condition.
The first step in diagnosing any driveability problem is
verifying the customer's complaint with a test drive under the
conditions the problem reportedly occurred.
Before entering self-diagnostics, perform a careful and
complete visual inspection. Most engine control problems result from
mechanical breakdowns or poor electrical connections. Before
condemning the computerized system, perform each test listed in this
article.
Two different module systems are used for powertrain control
of diesel engine. The Engine Control Module (ECM), located on left
side of engine, is used to control the fuel system. See Fig. 1. The
Fuel Pump Control Module (FPCM) located on pump, is a separate
component of ECM.
The Powertrain Control Module (PCM), located at right rear of\
engine compartment, is used for charging system, transmission and
speed control functions. CCD Bus circuits connect the various vehicle
control modules. These circuits are connected between ECM and PCM to
allow communication between modules.

PRELIMINARY INSPECTION & ADJUSTMENTS

Fig. 6: Locating Intake Manifold Air Heater

NOTE: Restricted low-pressure fuel lines from fuel tank to fuel
transfer pump, fuel heater and fuel filter/water separator
may cause starting problems and prevent engine from
accelerating. Restricted high-pressure fuel lines from fuel
injection pump to fuel injector may cause starting problems,
poor engine performance and excessive Black smoke.
11) Check all fuel supply and returns lines for damage,
kinking or leakage. Check throttle linkage for binding. Check for a
stretched or disconnected throttle return spring.
12) Ensure all ground connections are tight and free of
corrosion. Ensure accessory drive belt is not damaged or slipping.
Check for loose or defective electrical connection on Crankshaft
Position (CKP) sensor. See Fig. 1.

13) On A/T models, ensure all electrical connectors are clean
and properly connected to electrical plugs on transmission case. On
all models, check for loose or defective electrical connections on
starter and starter solenoid.
MECHANICAL INSPECTION
Compression
Manufacturer does not provide information for checking
compression.
FUEL SYSTEM
AIR IN FUEL SYSTEM
NOTE: Air in the fuel system may cause hard starting, rough
running, excessive smoke, poor engine performance, engine
misfire, poor fuel economy and fuel knock. Air may enter fuel
system whenever fuel supply lines, fuel filter/water
separator, fuel injection pump, fuel injectors or high
-pressure fuel lines are removed or disconnected.
1) Inspect all low-pressure fuel lines from fuel tank to fuel
transfer pump, fuel heater and fuel filter/water separator for signs
of leakage. Inspect all high-pressure fuel lines for signs of leakage.
See FUEL INJECTOR & HIGH-PRESSURE FUEL LINES under FUEL SYSTEM.
2) After repairing fuel leak, bleed air from fuel system. See
FUEL LINE BLEEDING under FUEL SYSTEM in REMOVAL, OVERHAUL &
INSTALLATION - TRUCKS - DIESEL article.
FUEL HEATER
1) Fuel heater is located in fuel filter/water separator. See
Fig. 1 . Fuel heater uses a fuel heater temperature sensor for
controlling operation of the fuel heater.
2) A defective fuel heater may cause excessive wax build-up
in the fuel filter/water separator during cold ambient temperatures.
Wax build-up may cause hard starting, prevent engine from
accelerating, low power, Blue smoke or White smoke. For testing of
fuel heater and fuel heater temperature sensor, see SYSTEM & COMPONENT
TESTING - TRUCKS - DIESEL article.
FUEL HEATER RELAY
Ensure fuel heater relay, located in power distribution
center is installed correctly and that terminals are not corroded. For
fuel heater relay testing, see SYSTEM & COMPONENT TESTING - TRUCKS -
DIESEL article.
FUEL FILTER/WATER SEPARATOR
NOTE: A blocked or restricted fuel filter/water separator may cause
starting problems, prevent engine from accelerating, low
power or White smoke. If an excessive amount of water
collects in filter/separator in a short period of time, it
may be necessary to drain and clean fuel tank.
1) When ignition switch is first turned to ON position,
WATER-IN-FUEL (WIF) warning light should come on for 2 seconds to
perform bulb and wiring circuit test and then go off. WATER-IN-FUEL
(WIF) warning light is located on instrument panel, just below the
