Inspection and verification
WARNING: Make sure that all suitable safety precautions are observed when carrying out any work on the fuel system. failure to
observe this warning may result in personal injury:
REFER to:
Important Safety Instructions
(100-00 General Information, Description and Operation).
CAUTION: Make sure that absolute cleanliness is observed when working with these components. Always install blanking plugs to any
open orifices or lines. failure to follow this instruction may result in damage to the vehicle.
1. Verify the customer concern.

Make sure that the immobilizer system is disarmed. Check the battery condition
and state of charge. Check that the engine turns by hand. Check the starting
system and circuits. Refer to the electrical guides. Check for DTCs indicating an
ECM relay or park/neutral switch fault. Rectify as necessary.

Make sure that the immobilizer system is disarmed. Check the fuel level and
condition. Draw off approximately 1 ltr (2.11 pints) of fuel and allow to stand for
1 minute. Check to make sure there is no separation of the fuel indicating water
or other liquid in the fuel. Check the low-pressure fuel system for leaks/damage,
check for air ingress. Check the air cleaner element. Check that fuel flows
through the fuel filter. Check for DTCs indicating a fuel metering valve or
injector fault. Check for DTCs indicating an engine management sensor fault.
Check the valve train, check the compressions,
REFER to:
Engine
(303-00 Engine System - General Information, Diagnosis and
Testing).
Check the catalytic converter condition, etc. Check for diesel particulate filter
DTCs. Refer to the warranty policy and procedures manual if an ECM is suspect.
