Mechanic's Pro Tip

On the 1.3 MultiJet start with the fuel filter and air leaks in the low-pressure lines. On the Ducato 2.3 the high-pressure pump and its pressure regulator are known weak points. Do an injector back-leak test before replacing the pump.

  1. 1.Clogged fuel filter

    Most likely

  2. 2.Air leak in low-pressure lines

  3. 3.Worn high-pressure pump

  4. 4.Faulty pressure regulator or rail sensor

  5. 5.Excessive injector back-leak

Step-by-step diagnostic guide

  1. 1

    Read codes and compare requested and actual rail pressure.

  2. 2

    Replace or check the fuel filter and look for air in the lines.

  3. 3

    Do an injector back-leak test.

  4. 4

    Check the pressure regulator and rail sensor.

  5. 5

    Repair, clear codes and test drive.
