Toyota RAV4>> Fuel system and system of release of the fulfilled gases>> The general check of fuel system>> Check of the fuel pump
The general check of the fuel pump. If there is a suspicion on insufficient productivity and reduction of pressure created by the fuel pump, execute following actions:
– Check up a condition and degree заряженности the storage battery and, if necessary, charge it;
– Check up serviceability of a safety lock in a feed circuit of the fuel pump;
– Check up a condition of fuel tubes and hoses on absence of leaks;
On hearing check up working capacity of the fuel pump. The assistant should turn the ignition key in position «ignition is included», thus you during 2 with should hear click and the noise created by the pump (noise from work of the fuel pump it is the most convenient to listen through a jellied mouth of a fuel tank). If the fuel pump does not work, check up an electric feed circuit of the fuel pump. If the fuel pump works, but does not create demanded pressure, it is necessary to check up the pressure created by the pump.
Check of the pressure created by the fuel pump. For pressure check in fuel system it is necessary to have a manometre and the corresponding adapter for connection to fuel system taking into account following remarks:
– On models till 2001 of release fuel hoses are connected by hollow bolts with washers to the fuel filter, the fuel filter is established on an arm on the left side in a motor compartment;
– On models since 2001 of release fuel hoses incorporate quick-detachable connectors, the fuel filter is established on the block of the fuel pump.
Dump pressure in fuel system.
Connect a manometre for pressure measurement as follows:

Fig. 5.1. An arrangement of a hollow bolt of fastening of a hose of an exit of fuel from the fuel filter on models till 2001 of release


– On models till 2001 of release remove the block of the relay and safety locks from an arm and disconnect a hose of an exit of fuel from the fuel filter and connect the manometre adapter to an exit of the fuel filter (fig. 5.1);

Fig. 5.2. An arrangement of a connector of a fuel pipe on models since 2001 of release


– On models since 2001 of release separate a connector of a fuel tube about a distributive fuel highway and to it connect the manometre adapter (fig. 5.2).
Include ignition, thus the fuel pump should work 2 with.
Take readings on a manometre. If pressure of fuel exceeds rating value, replace a pressure regulator. If pressure of fuel below rating value, the fuel filter and-or fuel tubes can be littered, leaks of fuel take place or the fuel pump and-or a pressure regulator are faulty.
Start up the engine and warm up it to working temperature. Check up pressure of fuel. If pressure of fuel below rating value the obvious reasons of it, probably also are not found out, the regulator of pressure and-or the fuel pump have defects. In this case it is recommended to replace a regulator of pressure and the fuel pump.
Switch off the engine and constantly supervise pressure in fuel system which should be supported to constants. Through 5 mines after deenergizing of the engine pressure in fuel system should be 150 кПа. If pressure has decreased to much lower size, the regulator of pressure and-or the fuel pump have defects or негерметична a distributive fuel highway.
After check of pressure of fuel dump pressure in fuel system and disconnect a manometre with the adapter.
