Install the appropriate tool for fuel pressure control
with the pipe fitted with the pressure gauge on the
delivery pipe..
Check during regular operation by placing the ap-
propriate tool between the pump and the injector.
With the battery voltage> 12 V check that the fuel
pressure is 2.5 BAR and that the input current is
1.4 to 1.8 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. 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
