Specification Desc./Quantity
9 Fuel injector
10 Lambda sensor
11 Electric fan starter
When switched to "ON", the fuel pump starts to rotate for two seconds and then stops. When the engine
starts up, in the presence of rpm timing signal the pump is continuously supplied.
ELECTRICAL DATA
•
Pump winding resistance ~ 1.5 Ohm
•
Input current during normal functioning 1.4 ÷ 1.8 A
•
Input current to the closed hydraulic circuit ~ 2 A (to be checked with specific tool for fuel
pressure control, choking the circuit on the return pipe)
Check the efficiency of injection load 15 A fuse No.
5.
Check the efficiency of live control unit power sup-
ply 7.5A fuse No. 10 .
Check the efficiency of the injection load remote
control: Check the resistance of the energising coil
between pins 86 and 85: 40 to 80 Ohm
Apply a voltage of 12V to pins 86 and 85; make
sure that there is continuity between pins 30 and
87 of the remote control.
