Repair and car operation

5.2.3.2. The main relay of injection and the relay of the fuel pump

THE GENERAL DATA

Check of the main relay (1988-89)

1, 2, 3, 4. Contacts

Check of the main relay (after 1990)

1, 2, 3, 4. Contacts

Check

Check of the relay of the fuel pump

1. The relay of the fuel pump 2. Подколенник 3. Боковина

PERFORMANCE ORDER

1. Two relays are included in an electric chain of fuel system. 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. 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. The relay is on a mudguard of a wheel niche from outside the driver. 4. If pressure from the battery is present on both relays check up relays.

THE MAIN RELAY

Check of the main relay with запитыванием contacts (1988-89)

1, 2, 3, 4. Contacts 1. An ohmmeter

Check of the main relay with запитыванием contacts (after 1990)

1. An ohmmeter 2. The battery

PERFORMANCE ORDER

1. An ohmmeter check up integrity of a chain between contacts 1 and 3 (fig. Check of the main relay with запитыванием contacts (1988-89)) see. Between contacts 2 and 4 ohmmeter should show rupture. 2. On conclusions 1 and 3 submit pressure from the battery. 3. Between conclusions 2 and 4 should be the closed chain. 4. If results of tests differ, the relay replace.

INCLUSION OF THE FUEL PUMP

PERFORMANCE ORDER

1. An ohmmeter (1) check up integrity of a chain (2) between conclusions +В1 and FPR and +В2 and FP. 2. Between contacts +В and PR the ohmmeter should show rupture. 3. On conclusions +В1 and FPR submit pressure from the battery. 4. Now between conclusions +В and FP there should be a closed chain. If results of tests differ, the relay replace.

The RELAY of INCLUSION of the FUEL PUMP (1996)

Check of the relay of the fuel pump with запитыванием coils

1. An ohmmeter 2. The closed chain 3. The battery

Check of the relay of the fuel pump (1996)

1, 2, 3, 4, 5, 6. Contacts 1. The opened chain 2. The closed chain

PERFORMANCE ORDER

1. Between conclusions 3 and 5 should be the closed chain (fig. Check of the relay of the fuel pump (1996 see)). 2. Between conclusions 3 and 5 ohmmeter should show resistance 80 Ohm. 3. On conclusions 1 and 5 submit pressure from the battery. 4. Between conclusions 1 and 2 should be pressure from the battery, and between conclusions 3 and 5 should be the closed chain. 5. If results of tests differ, the relay replace.

The RELAY of the CHAIN of the FUEL PUMP (1988-94)

Check of the relay of a chain of the fuel pump with запитыванием coils (1988-94)

1. An ohmmeter 2. The closed chain 3. The battery

PERFORMANCE ORDER

1. Check up chain presence between contacts ST and E1 (fig. Check of the relay of a chain of the fuel pump with запитыванием coils (1988-94), and also between conclusions +В and FC see. 2. Between conclusions +В and FP the ohmmeter should show rupture. 3. On conclusions ST and E1 submit pressure from the battery. 4. Between conclusions +В and FP there should be a closed chain. If results of tests differ, the relay replace.

The RELAY of the CHAIN of the FUEL PUMP (1995)

The procedure for test is similar to check of the main relay (see above).

RESISTANCE OF THE RESISTOR OF THE PUMP

PERFORMANCE ORDER

1. Resistance of the resistor of the pump should be 0,73 Ohm at normal temperature. 2. Otherwise the resistor replace.
