5.3.4. Check of the main relay of system of injection of fuel (EFI) and relay of the fuel pump

GENERAL INFORMATION

Check of the main relay of injection


A.Mezhdu conclusions should be a chain

B. Gap

PERFORMANCE ORDER
1. Two relays are switched on in an electric chain of fuel system – the EFI relay and the pump relay. The EFI relay is mounted in the relay block in a motor compartment, the relay of the pump is under the forward panel. At first check tension existence from the battery on the main relay, and then on the relay of the fuel pump.
2. Disconnect the main relay from the socket, then include ignition (the engine do not start) and check tension existence from the battery on a place of its connection.
3. If tension from the battery is, put the main relay on a place and check tension existence from the battery on the relay of the fuel pump.
4. If tension from the battery is present on both relays, check relays.

Main EFI relay

PERFORMANCE ORDER
1. An ohmmeter check chain existence between conclusions 1 and 2 and 3 and 4.
2. On conclusions 1 and 2 submit tension from the battery. Now between conclusions 3 and 4 should be the closed chain. If results of tests differ, the relay replace.

Arrangement of the relay of the fuel pump on and/m Toyota 4 Runner/Hilux/Surf

Check of the relay of the fuel pump

A. Between these conclusions there should be a chain

B. Gap

PERFORMANCE ORDER
1. An ohmmeter check integrity of a chain between contacts according to the scheme.
2. On conclusions 1 and 2 submit tension from the battery. Now between conclusions 3 and 4 should be the closed chain. If results of tests differ, the relay replace.
