Hello there. A few common faults will cause your 2009 BMW 328i to not start after it is parked. You have done great in having the battery, starter, and the alternator checked as those will cause these symptoms. Other possible causes are the fuel pump, ignition switch, crankshaft position sensor, or a wiring harness fault.

A qualified technician, such as one from YourMechanic, will be able to determine why the car is not starting and suggest the necessary repairs.
