Question about BMW Z3
I'm not sure about your car but many have a check valve in the gasoline line that prevents fuel from being sucked back into the tank when the air (and car) cools down. The check valve may have failed a little, allowing fuel to creep past.
This creates the problem you have with starting since you have to wait for fuel to fill the line and build pressure again.
If you are adventurous, you could disconnect the fuel line under the hood when the car has been off overnight and then briefly have someone turn the key to see if you have an instant, solid stream of fuel coining out of the line.
If it takes some seconds, then the line was empty.
After the car has been driven, the fuel just takes time to be sucked back to the tank.
