Some Mercedes-Benz ML320 owners report experiencing intermittent starting problems and occasional stalling while driving. These issues may stem from a variety of factors, including a faulty crankshaft position sensor or problems with the battery and electrical connections, which should be in good condition and tested under load. Additionally, some owners find that fuel delivery issues, such as being fuel-starved when warmed up, can contribute to stalling. The use of diagnostic tools like Xentry is often crucial for identifying these starting issues. Furthermore, the Drive Authorization System must enable the start, requiring proper electrical power, fuel, and spark for successful engine cranking. Owners also report that testing the neutral safety switch is important, especially if the no-start problem occurs in either Park or Neutral gear. To avoid dangerous situations or serious engine damage, it is recommended that owners refrain from driving if they suspect issues like a bad ignition coil. Addressing these factors systematically can help resolve the intermittent starting and stalling concerns in the ML320.
