Service of the fuel pump
|
|
For performance described below procedures the suitable measuring instrument of pressure of fuel (manometer) and the three-running union be required. |
Models of 3.0 l
Check of pressure of fuel
|
|
It is important, that during check of a gasoline pump passableness of fuel lines and the filter was not broken. Otherwise the probability of unreasonable replacement of the pump by false results of measurements is not excluded. |
|
|
Establish drain capacity under a separator of fuel evaporations.
|
|
Disconnect from a separator an inlet fuel hose an illustration) and закупорьте the open end of the union of its connection on a separator.
|
Connect to a hose a suitable manometer and include ignitions (turn a key in the situation ON).
Compare the manometer indication to standard requirements (see size tables and adjustments at the end of the Management). In case of need replace the fuel pump.
|
|
Check of serviceability of functioning of the fuel pump
|
|
Check a condition of safety locks of management of the fuel pump and the engine, located in the assembly block. Burned down replace.
In a luggage compartment give fixing screws and remove fastened hooks.
Give fixing screws and remove furnish of fastening of a rug from shutters of a door of a back.
Combine a rug forward and give screws of fastening of a cover of access. Uncover.
Disconnect electroconducting from a gasoline pump (see an accompanying illustration).
Connect the voltmeter between red and green (+) and black (-) negative wires near the electric socket of a plait. Turn the engine and read the voltmeter instrument.
If the voltmeter fixes tension of the battery, check conductivity existence between red and green and black wires near the electric socket of a gasoline pump. If conductivity is absent, replace a gasoline pump.
|
|
If there is no tension of the battery, remove the furnish panel under the assembly block of safety locks and disunite the electric socket of the control unit the fuel pump (see an accompanying illustration).
|
Check conductivity existence between a black wire and mass of the case. If conductivity is absent, check an electroconducting condition.
Disconnect a wire from the starter plug S.
Include ignition (a key in the situation ON) and measure tension between brown (+) a wire and in mass of the case of a body (-). Turn the ignition key in the situation START and again check tension. If tension of the battery is absent in both cases, check a condition of a safety lock of engine management and the corresponding electroconducting.
Turn a key in the situation ON and check tension between light green (+) a wire and in mass of the case of a body (-). If tension of the battery is absent, check a condition of a safety lock of management of a gasoline pump and the corresponding electroconducting.
Again connect the starter plug S. Connect the electric socket of the control unit a gasoline pump and start the engine. Connect a probe to white red (+) to a wire from a reverse side of the electric socket and check tension between this wire and mass of the case of a body (-). If tension of the battery is absent, check a condition of the generator of a plait of electroconducting.
At the working engine connect a probe to a green wire from a reverse side of the electric socket and check tension between this wire and mass of the case of a body (-). If tension of the battery is absent, check a condition of the sensor switch of pressure of oil and the corresponding electroconducting.
Disconnect the starter plug S. Turn the ignition key in the situation ON, connect a probe to green red wire from a reverse side of the electric socket of a gasoline pump and check tension between this wire and mass of the case of a body (-). Turn a key in the situation START and again measure tension. If tension of the battery is absent in both cases, replace the control unit with a gasoline pump.
If tension of the battery takes place, check a condition of electroconducting of a gasoline pump.

Disconnect a negative wire from the battery.
In a luggage compartment give fixing screws and remove fastened hooks.
Give fixing screws and remove furnish of fastening of a rug from shutters of a door of a back.
Combine a rug forward and give screws of fastening of a cover of access. Uncover.
Disconnect and закупорьте fuel hoses. Disunite the electric socket.
Give fixing bolts and take a gasoline pump with a sealing ring from a fuel tank.
|
|
Installation
Installation is made upside-down.
|
|
Make sure of serviceability of a condition of a sealing ring.
Check a condition of contacts of the electric socket.
|
|
Models of 4.2 l
Check of pressure of fuel
|
|
It is important, that during check of a gasoline pump passableness of fuel lines and the filter was not broken. Otherwise the probability of unreasonable replacement of the pump by false results of measurements is not excluded. |
|
|
Disconnect a hose of supply of fuel from the carburetor.
Disconnect a hose of return of fuel from a gasoline pump and закупорьте the union on the pump.
Turn on the three-running union consistently in the line of supply of fuel to the carburetor.
Connect to the remained free branch of the union a suitable measuring instrument of pressure of fuel (manometer).
|
|
Approximately for 60 seconds turn on the engine for a conclusion from system of air jams. |
Driving the engine on various turns, watch manometer indications. Compare results to standard requirements (see size tables and adjustments at the end of the Management). In case of need replace a gasoline pump.
|
|
Removal and installation
Removal
|
|
Disconnect a negative wire from the battery.
Mark hoses suitable to a gasoline pump and departing from it.
Disconnect fuel hoses from a gasoline pump.
Give fixing screws and take the pump with an insulator and laying (see an accompanying illustration).
In case of need check the pump as it is described below.
|
|
Installation
|
|
Installation is made upside-down.
In case of need replace an insulator and laying.
|
|
Check of serviceability of functioning of the fuel pump
|
|
Remove the fuel pump.
Lower the pump in the capacity filled with fuel and wash out it, having several times pressed the drive lever.
Merge fuel from the pump. Block a finger the inlet union of the pump and work as the drive lever. Holding the lever in the top situation, release a finger - the sound of absorption of air should be audible.
Clamp a finger the final union and lift pressure in the pump, having worked as the lever. Pressure should keep within two-three seconds.
Again lift pressure in as it is described in the previous paragraph, then lower the pump in capacity with fuel and check it on leakages of air.
