My 325i wont start its weird, It cranks fast,battery is new (bmw battery)charged but when its cranking it seems the needles on the gauges go up and down as its cranking??and then I thought the battery may be low (even though its cranking fine) so I put the jump charger on it for a minute and tried to start it and it started up. drove the car for a while and charged the battery with the charger , for hours Green window on battery and tried to start it and same thing cranks fast but starts with jump charger only ??? also lately the car seems to smell like its running rich I dont use it a lot maybe someone has had a similar problem or ideas what to check, THANKS!!
