    2001 e46 m3 fuel issue?



    I have my 2001 BMW E46 M3 and recently the car started and idled for about 5 minutes but was running very rough and misfiring. As soon as I touched the gas pedal, it stalled and then would only crank without starting but sometimes it woild start and idle very rough, adding more fuel seemed to fix the issue. After adding gas, the car started up, ran much better, and now revs normally without shutting off. Because of that, I’m wondering if I have a bad fuel level sensor, inaccurate fuel gauge, a siphon/jet pump issue in the saddle tank, or possibly a fuel delivery problem. Has anyone experienced something similar on an E46 M3 where the car acts like it’s out of fuel even though the gauge shows fuel remaining? Any advice would be appreciated

    Fuel pumps are notorious for going bad. If your gonna throw some parts at it start with a fuel filter change followed by a new pump
