FUEL PUMP CONNECTOR
2. Ground (Black)
5. Injection load relay (Black-Green)
FUEL PUMP UNIT
Mechanical type pressure regulator operating at a
pressure of 3 BAR
Pump winding resistance: ~ 1,5 Ohm
Verificare, commutando in « ON », la presenza di tensione batteria, per circa 2 secondi, tra il pin 5 del
connettore pompa e massa con connettore pompa staccato. Altrimenti verificare la continuità del cav-
etto tra pin 5 connettore pompa e zoccolo del teleruttore carichi iniezione.
Verificare l'efficienza della linea di massa della pompa carburante misurando la continuità tra pin 2
connettore pompa e massa.
Circuit leak test
Install the specific tool for checking the fuel pressure, with the pipe fitted with the gauge.
Check during regular operation by placing the ap-
propriate tool between the pump and the injector.
With battery voltage > 12 V check that the fuel
pressure is 3 BAR and that the input current is ~2.8
A
With the battery voltage > 12 V, check the pump flow rate by disconnecting from the injector the pipe
equipped with the pressure gauge of the appropriate tool. Get a graded burette with a flow rate of
approximately 1 L. Rotate the pump using the active diagnoses of the palm top computer. Using a pair
of long flat needle-nose pliers, choke the fuel pipe making the pressure stabilise at approx. 2.9 ÷ 3 BAR.
