Low fuel pressure supply circuit check
Connect the pressure transducer of the Examiner/SDC diagnostic instrument between the diesel filter (1a) and the pressure pump (1b).
Turn the ignition on (MAR).
Check, within 30 seconds, that the pressure gauge's reading is between 1.8 and 3.0 bar.
The pump in the tank stops after 30 seconds.
Make sure that the taps and adjustment screws next to the pressure gauge are open (except those on pipes not connected to the system).
