Good afternoon

Would anyone out there know how I can solve my fuel pump issue.
I own a 633CSI and have no power going to my fuel pump . I bought the car as a non working project ,I'm not sure about the history but I was advised that it could have a fuel relay issue. does anyone know where I can locate this relay and are these fuel relay issues common in the e24's.
Also , the engine has not been started for 12 years , I managed to turn it over by starter only ( with plugs off and oil in the bores) the gear box (which was perfect I was told at the time) can not shift into gear straight away , it's actually a slow process and it feels like there is no "feel" in the shift ...could this be due the oil being over 12 years old?

many thanx
