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 the socket of the fuel pump, start the engine and wait while it will not stop in connection with production of fuel from топливопроводов and the fuel highway.

Prevention

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


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

Inhaling moment: 25-35 N • m

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

Pressure of fuel: 350 kPas
9. If the measurements executed in steps 7 and 8, do not correspond to demanded value of pressure of fuel, define the reason and execute necessary repair.
Condition
Probable cause
Elimination method
Pressure of fuel the too low a. The fuel filter is polluted. a. Replace the fuel filter.
b. Leaks from return the fuels caused by bad consolidation of a regulator of pressure. b. Replace a pressure regulator.
Pressure of fuel the too high a. Zalipaniye of a regulator of pressure of fuel. a. Replace a pressure regulator.
b. The pipeline of return of fuel is hammered or will bend b. Replace the pipeline of return of fuel
10. Stop the engine and through 5 mines on a manometer read value of pressure of fuel which should not change. If pressure of fuel considerably decreased, define the reason and execute necessary repair.
Condition
Probable cause
Elimination method
Pressure of fuel after a stop of the engine decreases slowly a. the fuel nozzle is not tight a. Replace a fuel nozzle
Pressure of fuel after a stop of the engine decreases very quickly a. The control valve of the fuel pump is open Replace the fuel pump
11. Remove pressure in fuel system.
12. Disconnect a hose and a manometer.

Prevention

Close connection by a towel to exclude the razbryzgivany fuels, caused by residual pressure in топливопроводе.


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