2.7.3. Check of operability of the fuel pump

Switch off ignition.
Check operation of the fuel pump, having submitted tension of the storage battery on conclusions electric the socket of the electric motor of the pump.

NOTE
The fuel pump is established in a fuel tank therefore the sound of its work is audible only at the removed stopper of a bulk mouth of a tank.


Pressure stock-taking in a bringing fuel hose
Fig. 2.210. Pressure stock-taking in a bringing fuel hose


Be convinced that the bringing fuel hose is under pressure, having compressed it a hand (fig. 2.210).

Check of pressure of fuel

The hatch for access to the fuel pump from car salon (the back seat is combined)
Fig. 2.211. The hatch for access to the fuel pump from car salon (the back seat is combined)


Combine a back of a back seat, then cast away forward the combined back seat (fig. 2.211).

The hatch (is open) for access to the fuel pump
Fig. 2.212. The hatch (is open) for access to the fuel pump


Screw-driver open a cover of the hatch of the fuel pump in the car bottom under a back seat (fig. 2.212).
For pressure dumping in fuel pipelines and hoses start the engine at the disconnected fuel pump and wait, while the engine will stop.

NOTE
Before disconnecting the pipeline and a hose of supply of fuel, it is necessary dump pressure of fuel to exclude its emission.

Disconnect the plug from a minus conclusion («–») the storage battery and connect the electric socket of the fuel pump.

Manometer connection for measurement of pressure of fuel in system
Fig. 2.213. Manometer connection for measurement of pressure of fuel in system


Attach a control manometer (fig. 2.213) to the fuel filter by means of an adapter. Reliably tighten the union of fastening of an adapter of a manometer of pressure of fuel.
Attach the plug to a minus conclusion («–») the storage battery.
Turn on the fuel pump, having submitted tension of the storage battery on conclusions of the electric socket of the pump.
After creation of pressure of fuel be convinced of absence of leakages of fuel through a control manometer and its connections.
Start the engine and leave it to idle.
Check pressure of supply of fuel.
Nominal rate: 350 kPas (3,5 kgfs/cm2).
If pressure of supply of fuel does not correspond to norm, define the reason and eliminate malfunction, as shown below.
Stop the engine and track pressure of fuel on a control manometer: pressure should keep approximately within 5 minutes. If pressure falls, define speed of falling. Define and eliminate the pressure drop reason, as shown below.

NOTE
At a detachment of a hose cover the union with a rag to exclude fuel emission as топливопровод is under residual pressure.

Replace a sealing ring of the union of a hose.
Attach a fuel hose to a branch pipe of the fuel pump and tighten the union.
Be convinced of absence of leakages of fuel.

Replacement of the fuel filter and fuel pump
Dump pressure in fuel pipelines and hoses, having executed the following:
Remove a pillow of a back seat and separate the electric socket of the fuel pump.
Start the engine, wait, while the engine will not stop, switch off ignition.

Removal of the minus plug of the storage battery
Fig. 2.214. Removal of the minus plug of the storage battery


Disconnect the plug from a minus conclusion («–») the storage battery (fig. 2.214).
Connect the electric socket of the fuel pump.
Unscrew bolts with an ear, holding from a provorachivaniye of a nut of fastening of the fuel filter.

NOTE
Cover the fuel filter with a napkin for prevention of an effluence of the fuel which has remained in it.

Unscrew bolts of fastening of the fuel filter and take out the filter from a fastening collar.
After replacement of the fuel filter be convinced of absence of leakages of fuel.

Replacement of the limiter of a modulation (the on-off valve)

Modulation limiter (the on-off valve)
Fig. 2.215. Modulation limiter (the on-off valve)


Disconnect a branch hose паров fuels (fig. 2.215), then remove the modulation limiter.

Adjusting position of the limiter of a modulation
Fig. 2.216. Adjusting position of the limiter of a modulation


Attach the modulation limiter to топливопроводам in the correct situation (fig. 2.216).

Replacement of the sensor of the index of level of fuel
Remove a stopper of a bulk mouth of a fuel tank for pressure dumping in a tank.

Sensor of the index of level of fuel and fuel pump
Fig. 2.217. Sensor of the index of level of fuel and fuel pump


Unscrew screws of fastening of the sensor of the index of level of fuel and take out the sensor from a tank (fig. 2.217).
