Check during regular functioning by placing the
appropriate tool between the pump and the injec-
tor.
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 capacity of the pump flow rate by disconnecting from the
injector the pipe equipped with the pressure gauge of the appropriate tool. Make a graded burette
available with a flow rate of approximately 1 L. Rotate the pump using the active diagnosis 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. Be careful not to further choke pipes if pressure remains evenly at 3
BAR while flow rate decreases. Check that within 15 seconds the pump has a flow rate of approx. 300
cm³.
