The excavator cannot be started, which can be called difficult start, non-combustible, etc. It is one of the most common faults of excavators. It can be divided into two cases.

10 reasons why the excavator won't start:

1. The battery clamp is loose, which makes it difficult for the excavator to start.

2. Excavation of the electric battery is insufficient, or the battery head is loose, resulting in poor contact.

3. Circuit failure, loose relay box connector, or fuse in fuse box.

4. The starter motor or generator fails and cannot generate electricity normally, resulting in insufficient electricity.

5. The excavator cannot start in winter, which may be caused by waxing of the excavator diesel.

6. The excavator is matched with unsuitable fuel. In the winter, diesel with a large viscosity should be used, and in summer, a diesel with a low viscosity should be selected.

7. The engine cylinder pressure of the excavator is lacking and the engine valve is not tightly closed.

8. It is difficult to start the excavator hot car. There may be something wrong with the oil pump or nozzle of the excavator.

9. Malfunction caused by too much water in diesel or too much air mixed in diesel.

10. Failure of the excavator solenoid valve, wear of the diesel pump plunger, etc. will also cause startup failure.
