I have a 2007 530i recently my car started missing real bad then I died I figured it was the fuel pump. I ordered a fuel pump and a fuel filter sending unit. Before I replaced them I started the car it started after 5 minutes it started hesitating and died wouldn’t start again. So I replaced both units and it’s doing the same thing it stated that started hesitating then died no start any suggestions the fuel pump seems to loose pressure after warming up
