2. Use a suitable hand tool in order to rotate the
crankshaft. If the crankshaft does not rotate freely,
check the engine for the following problems:
•
Seized piston
•
Defects in the drive gears
•
Fluid in the cylinder bores
•
Improper timing of valves
3. If the crankshaft rotates freely proceed to "Air
Intake and Exhaust System".
Air Intake and Exhaust System
1. Check the air filter restriction indicator, if equipped.
2. Ensure that the air filter is clean and serviceable.
3. Check the air intake and exhaust systems for the
following defects:
•
Blockages
•
Restrictions
•
Damage to lines or hoses
4. Repair any defects before attempting to restart
the engine.
5. If the engine will not start proceed to "Glow Plugs".
Glow Plugs
1. Check the operation of the glow plugs. Refer to
Systems Operation, "Glow Plugs - Test".
2. If necessary, replace faulty glow plugs. Refer to
Disassembly and Assembly, "Glow Plug - Remove
and Install".
3. If the repairs do not eliminate the fault, proceed to
"Valve Lash".
Valve Lash
1. Check the valve lash and reset the valve lash if
it is necessary. Refer to Testing and Adjusting,
"Engine Valve Lash - Inspect/Adjust".
Ensure that the repairs have eliminated the active
diagnostic codes before attempting to restart the
engine.
Try to start the engine. If the engine does not start,
verify that the crankshaft is rotating.
If the engine will not start proceed to "Fuel Supply".
Fuel Supply
1. Visually check the fuel tank for fuel. The fuel
gauge may be faulty.
2. Ensure that the fuel supply valve (if equipped) is
in the full OPEN position.
3. If the temperature is below 0 °C (32 °F), check
for solidified fuel (wax).
4. Check the primary filter/water separator for water
in the fuel.
5. Check for fuel supply lines that are restricted.
6. Check that the low pressure fuel lines are tight
and secured properly.
7. Check the fuel filters.
8. Check the diesel fuel for contamination. Refer to
Testing and Adjusting, "Fuel Quality - Test".
9. Check for air in the fuel system. Refer to Testing
and Adjusting, "Air in Fuel - Test".
10. Ensure that the fuel system has been primed.
Refer to Testing and Adjusting, "Fuel System -
Prime".
11. Check the fuel pressure. Refer to Testing and
Adjusting, "Fuel System Pressure - Test".
12. If the repair does not eliminate the fault refer to
"Low Compression (Cylinder Pressure)".
Low Compression (Cylinder Pressure)
1. Perform a compression test. Refer to Testing and
Adjusting, "Compression - Test ".
2. If low compression is noted on any cylinders,
investigate the cause and rectify the cause.
Possible causes of low compression are shown
in the following list:
• Loose glow plugs
•
Faulty piston
•
Faulty piston rings
• Worn cylinder bores
•
Worn valves
•
Faulty cylinder head gasket
• Damaged cylinder head
3. Perform all necessary repairs.
