In order to check the cause of starting difficulties, i.e. check that fuel is getting to the injectors, loosen the union nuts on the two injectors and start the engine without preheating until fuel comes out from under the nuts. Tighten the cap nuts to 20 Nm and start the engine in the normal way.
Attention: If air is not automatically purged from the system, the following must be done.
During work, cleanliness and safety regulations must be observed.
Make sure that diesel fuel does not get on the cooling system hoses. If this does happen, clean the hoses immediately. If the hoses are damaged, they must be replaced.
Remove the fuel line going to the injection pump from the fuel filter by pressing the brackets. Collect leaked fuel.
Insert a suitable hose into the connection thread and guide it into the vessel.
Pull the fuel pump relay and bridge the contacts in the relay socket so that the fuel priming pump supplies fuel.
When fuel emerges at the connection, remove the jumper and insert the relay.
Install the fuel line, pre-lubricating the gaskets with petroleum jelly or acid-free grease. Replace damaged gaskets.
Loosen the cap screw (1) on the injection pump for two turns.
Turn the engine over with the starter until fuel comes out from under the plug bolt. Collect leaking fuel.
Tighten the blind bolt (1) torque 25 Nm.
After unscrewing the bolts, remove the casings from the intake manifold.
Loosen all union nuts on the injectors using the special tool on the high pressure fuel lines. Turn the engine over with the starter until fuel comes out. Then tighten the nuts to 20 Nm. In case of leaks, tighten the nuts with a torque of 25 Nm.
Carefully collect leaked fuel in the engine compartment.
Install the engine covers.
