Task

Actuating fuel pump at

Ignition ON: Actuate fuel pump for about 1 s (audible) as a full running protection. An engine start must be completed, however, before repeated actuation of the fuel pump.

when starting engine via the first signals of the crankshaft position sensor (L5/5 on Engine 120)

When engine running by means of TN engine speed signal.

Design/function

The fuel is actuated through the fuel pump relay.

The fuel pump relay is actuated through a ground signal from the ME control unit. When the contact is closed, the fuel pump (M3) is linked through circuit 87 to circuit 30 (B+). The voltage supply is fused to the fuel pump.

On engine 120, the fuel pump is actuated by the right ME-SFI control unit (N3/12).

If the fuel pump does not run, check the voltage supply of the ME control unit and the fuse of the fuel pump.

Check electric connection at fuel pump for corrosion.
