ENGINE MECHANICAL - Troubleshooting (Diesel Engine Diagnosis)

TROUBLESHOOTING

Diesel Engine Diagnosis

GENERAL

1. Diesel engine problems are usually caused by the engine or fuel system. The injection pump is very rarely

the cause of fuel system problems.

2. Before beginning fuel system tests, first check that the engine compression, valve timing and other major

systems are within specifications.

PRELIMINARY CHECKS

1. Before performing fuel system checks, ensure that the engine is in good running condition. If necessary,

first check the compression, timing and major components or systems.

2. Check the air filter, and clean or replace it if necessary.

3. Check that there is sufficient fuel in the tank.

4. Check if the fuel is contaminated with gasoline or other foreign elements. Only good-quality diesel fuel

should be used.

5. Bleed air from the system by pumping the priming.

6. Check for water in the fuel filter and fuel tank, and drain as necessary.

7. If the engine will not crank or if it cranks slowly, first troubleshoot the electrical system.
