6.3. Check of the pressure created by the fuel pump

PERFORMANCE ORDER
1. Remove a pillow of back sitting and remove the inspection panel of the fuel pump.
2. For pressure removal in fuel system disconnect a socket of the fuel pump, start the engine and wait while it will not stop in connection with development of fuel from топливопроводов and a fuel highway.

The prevention

Before separation топливопроводов remove pressure in fuel system, otherwise, the fuel which is under pressure, will intensively follow from fuel system.


3. Disconnect a wire from the negative plug of the storage battery and connect a socket of the fuel pump.
4. Connect to the fuel filter the manometre adapter (09353-24000, 09353-24100, 09353-38000) and tighten a bolt of fastening by the demanded moment.

The inhaling moment: 25-35 Н•м

5. Connect a wire to the negative plug of the storage battery.
6. Additional wires submit pressure to a socket of the fuel pump and check up, that there are no leaks of fuel from manometre connections.
7. Start the engine and leave it to work on frequency of rotation of idling.
8. Measure pressure of fuel.

Pressure of fuel: 350 кПа
9. If the measurements executed in steps 7 and 8, mismatch demanded value of pressure of fuel, define the reason and execute necessary repair.
Condition
The probable reason
Elimination method
Pressure of fuel too low a. The fuel filter is polluted. a. Replace the fuel filter.
b. Leaks from the fuel return, caused by bad consolidation of a regulator of pressure. b. Replace a pressure regulator.
Pressure of fuel too high a. Залипание a regulator of pressure of fuel. a. Replace a pressure regulator.
b. The pipeline of return of fuel is hammered or will drive b. Replace the pipeline of return of fuel
10. Stop the engine and through 5 mines on a manometre read value of pressure of fuel which should not change. If pressure of fuel has considerably decreased, define the reason and execute necessary repair.
Condition
The probable reason
Elimination method
Pressure of fuel after an engine stop decreases slowly a. негерметична a fuel atomizer a. Replace a fuel atomizer
Pressure of fuel after an engine stop decreases very quickly a. The control valve of the fuel pump is opened Replace the fuel pump
11. Remove pressure in fuel system.
12. Disconnect a hose and a manometre.

The prevention

Close connection by a towel to exclude разбрызгивание the fuel, caused by residual pressure in топливопроводе.


13. Replace a sealing ring on the hose end.
14. Connect a hose to a fuel highway and tighten a connecting nut the demanded moment.
15. Check up tightness of fuel system.
