–
| If the voltage tester does not light up again, check the cable connection between contact 23 at the relay position 4 and check the fuse for fuel pump for continuity and if necessary eliminate open circuit → Current flow diagrams and Fitting locations. |
–
| If the power supply, the actuation and the wiring of the fuel pump relay are O.K, replace the fuel pump relay. |
B - Check voltage supply and actuation of the fuel pump relay |
Note The actuation of the fuel pump relay can also be checked by means of the final control diagnosis → Chapter. |
–
| Remove the fuel pump relay - J17- from the relay carrier, relay position 4. |
–
| Connect the multimeter successively to the contacts 19 (positive, terminal 15 from the ignition lock) of the relay base and earth as well as 17 (permanent positive, terminal 30 of the battery) of the relay base and earth. |
Specified value: approx. battery voltage each |
