I was driving on the road than the engine just cut out. Try to restart, engine idle for a few seconds and than dies. I
bought this car brand new and it is the first time this happen to me. Car has over 360 000 km on clock.
Get the DTC's checked with a scan tool but it sounds like a Crank angle sensor issue
Sounds like a fuel pump issue I am not very familiar with a 320i but It sounds like the fuel pump failed on your vehicle. I would check fuel pressure. Hope this helps
It's either A. battery issue B. alternator or c. fuel pump. If it starts then dies and won't start again, it's the battery. If it starts and kind of runs but loses power, alternator. If it starts but won't run and all the electronics work, it's the fuel pump.
It could also be the mass airflow sensor going bad.
If it starts for a few seconds then stalls again it may be the coil if it has a single coil. When a coil gets hot its internal resistance builds and it can short out. When that happens it will often start for a few seconds but will either conk out on its own or when you step on the gas. Sometimes when the engine is cool it will actually work normally until it gets hot again.
