My BMW will start sometime and other times not. It always has power to interior. I will start it and drive it several times in a day and go out to start and nothing. It may sit over night and fire up.

The battery might be weak, check the voltage, should be 12.3 or more. Is it older than 5 years old? Time to replace. Also check your fuel pressure, might be a weak fuel pump.

Not enough information in the question. Does it turn over? What other information can you provide?

At 12.3 volts the battery is discharged. Look for a minimum of 2.2 volts per cell. 2.2 X 6 = 13.6 volts.
