Injection pump fuse burning

I need urgent help. I have a rodeo 1.9 diesel and burns the fuse check all cables and they are perfect. what can it be?

Well, if all cables are fine and not a dough derivation so that the fuse jumps, it may be that the pump itself is pump and when it is pens it needs more intensity to function so the fuse burns

Hello friend time, something similar happened to me in a mitsubishi L-200 now I do not know if the engine circuit will be the same or similar but on that occasion there was an incandescent spark plug that was burned and the inner filament had stuck with the body what caused that it was mass and burned the large fuse that is lodged near the battery if I do Check the spark plugs I wish it serves something greetings
