    Engine: B230F- There is no voltage going to the fuel pump(external). I
    replaced the fuel pump and also the relay. I think that I need to look
    at the control unit and/or the air mass meter? Hopefully, someone can
    get me started in the right direction, thanks!

    Check fuses and contact patch...corrosion is a problem;
    Is there KOEO 12v to the relay? Does the relay ground while cranking?
    If it grounds, does current flow through the switched side?;
    Check underhood wiring for rot.
