my 1993 325i was sitting for 2 years finally got around to replacing the fuel pump, relay, and fuse #18 . cycled the key to prime the pump and lo and behold it finally started.after engine warmed up it started loping up and down until it finally died. it restarts no problem but overnight i'm having trouble starting it up again the next day. have to prime all over again. i still need to replace the fuel filter and i'm leaning towards the fuel pressure regulator losing pressure overnight in the fuel system??? :crying: HELP :crying:
