THE GENERAL DATA

Check of the main relay of injection


A.Mezhdu conclusions should be a chain

B. Rupture

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

The main EFI-relay

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

Check of the relay of the fuel pump

A. Between these conclusions there should be a chain

B. Rupture

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