Disconnect fuse for fuel pump (fuse 28)
at the fuse holder and connect the
– voltage tester between earth and one of
the two contacts of the fuse for the fuel
pump → Current flow diagrams and
Fitting locations.
Switch on the starter motor for a short
–
time.
The fuel pump relay must be activated
(feel and hear), the voltage tester must
light up.
If the fuel pump relay does not connect,

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,

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 →
Remove the fuel pump relay - J17- from
–
the relay carrier, relay position 4.
Checking voltage supply
– Switch on ignition.
