    HJ45 with H engine. Injector pump replacement.

    I had a problem initially, when I turned the key to activate the glow plugs I got nothing,, but when I turned to start I got power to the glow plugs. After cleaning the switch contacts it started to work. Starter wiring is covered in plastic protection so I cant get a useful photo.

You maybe need to clean the timing gear to find...
