Because of hard starts & fuel rail pressure immediately dropping to zero when the car is shut off, it appears my 2000 e320 wagon has an internal fuel leak.
I see plenty of Fuel Pressure Regulator (FPR) replacement tutorials for older & newer e320s, but none for year 2000. O'Reilly's lists no replacement part for a 2000 e320 Fuel Pressure Regulator. Is it possible the 2000 e320 has no FPR?
I've already replaced the fuel pump & filter. Please advise. Thanks, C.
