The lorry was working just fine, and suddenly it stopped on its own. We did the checks including wiring, and finally, we discovered that it was a blown fuse which was no longer supplying power to the power. The other guy came, he wanted to test the fuel pump. He connected a long cable from the battery directly to the fuel pump. Then the owner of the car, later on, called me telling me that the lorry is losing power, its power has now decreased.
My question is, does the electric fuel pump gets damaged (just like the starter motor armature?)
