the positive battery cable where it leads under the engine it looks like it is a clean cut but i think it has been hittin metal and arching and over time it has been burning deeper into the wire it is maybe between 1/8 1/4 in deep also when i turn the ignition to on i was told i would be able to hear the fuel pump kick on is that true if so i dont hear it

Any chance you can post a photo of that spot? If the engine cranks, the battery cables are able to pass really high current so they would not be causing other electrical problems. If you're looking at the smaller positive wire leaving the battery terminal, that one does feed other things that could be affected by arcing or a break in it.
