starting issues 2000 S500
 

hey everyone looking for a little help I have a 2000 S500 with 140K on it, recently I went out to start it and nothing. Turn the key everything powers up but will not turn over. I thought I heard a buzz under the car thinking it could be the starter I replaced it still nothing. Tried the extra keys nothing remote opperates fine lock unlock radio and all power items work, but no turn over any help and can this be a DYI or do I need the dealers help

buzz under car might be your ground wire.Clean ground area reassemble,maybe this will help you
