Wiring problems in a VR ute, no power ANYWHERE!!

[Sexbombdiggity1]

hi, just replaced the fuel pump in my Vr series II ute, ran for a minute now nothing!! fuel pump wont wind up at all, and now it wont turn over because im only getting 4V to the starter. im getting 12V to all my relays and fuses, but the fuel pump fuse is only getting 11V. should this be a drama? ive checked my start, ignitions, well to be honest all my relays and my car wont turn over! and to add to this, my main fuse wont come out, this its stuck? so i cant check that? do you think its my starter? or any other wiring faults? anyone herd of this sort of problem? any help will be VERY appreaciated. thanks
