Injection
Circuit leak test
Fit the specific tool for fuel pressure control with
the pipe fitted with the pressure gauge on the de-
livery pipe.
Checking under regular functioning by placing the
specific tool between the pump and the injector.
With >12V battery voltage, check that the fuel
pressure is 2.5 BAR and that the input current is
1.4 ÷ 1.8A
With the >12V battery voltage, check the pump
flow rate by disconnecting the pipe fitted with the
pressure gauge of the appropriate tool from the
injector. Place a graded burette with a flow rate of
approximately 1 L. Make the pump turn with the
active diagnosis on the palm top computer. Using
a pair of long flat needle-nose pliers, choke the fuel
hose making the pressure stabilise at approx. 2.5
BAR. Check that within 15 seconds the pump has
a flow rate of approx. 110 cm³.
