Possible malfunction
Elimination methods
1 The empty fuel tank or is littered the ventilating valve of a tank
To fill a tank, to wash out fuel-supply lines, to clear the ventilating valve
2 Availability of air in fuel system
To pump over fuel system, to eliminate an air suction
3 The electromagnetic valve of the diesel or the regulator of starting supply of fuel is faulty
To repair or replace
4 The fuel filter is littered
To replace the fuel filter
5 Fuel-supply lines of low pressure are littered
To restore sections of fuel-supply lines through passage
6 Fuel-supply lines of low pressure are littered
To wash out or replace fuel-supply lines
7 Leaky connections, fuel-supply lines leak or are broken
To tighten connections, to eliminate a leak
8 Deposits of paraffin in the fuel filter
To replace the filter, to use seasonal fuel 
9 Wrong advancing of injection of fuel

To replace the valve(s)
18 The effort of a buffer spring of the regulator of frequency of rotation of the diesel is not adjusted
To adjust effort of a buffer spring
19 The fuel supply advancing coupling is faulty
To repair or replace the coupling
20 Low compression
To restore a compression
21 The regulator of frequency of rotation of the engine is faulty or is not adjusted
To adjust or replace the regulator
22 The fuel pump of high pressure is faulty or does not give in to adjustment
To remove the pump and to give to repair
