FUEL PUMP POWER FEED

[overdalimit]

After some diagnosis of my fuel system, I tried this. I hooked a battery boost box to my aftermarket fuel pump. It ran for a long time then the pump stopped working. Now I left the wires coming from the truck connected to the fuel pump and all I did was hook up the battery box with alligator clips to the fuel pump pos. and neg. terminals. Upon inspection I found that the wire from my jumper box to the fuel pump (alligator clipped) has burnt in half. I disconnected the wires coming from the truck and hooked up the battery box directly to the fuel pump and it ran.

Has there been any cases that the trucks wiring became faulty or is this a common problem? Now, I am not getting any power through the pos. wire from the truck and I have checked the fuse (under the hood) and it is good? Is there another relay inline before the fuse.......or.....
