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.
