  • 2003 HPDI stopped getting spark to plugs

    testing new sideview scan on boat. started & stopped each engine a few times while motoring to determine direction of scan.
    port engine failed to restart after a few start/stops. cranks but doesn't spark.

    mechanic thinks its the regulator/rectifier but doesn't know how to test.

    anybody know how to test?

    never heard of spark being killed by battery charging system.
    Maybe Rodbolt17 will chime in soon

      cant happen.
      find a technician.
      that motor uses a 12V TCI( transistor controled ignition) system.
      its fired by inputs to the ECU from the 6 pulser coils.
      when the key is turned to on, does the medium pressure fuel pump cycle?
