Either the battery or starter is defective.
Battery with no load should be 12.6 volts or more.
BMW starters usually lasts as the engine life.
If battery and starter are OK, and car won't start, check the remote switch on the car key.
To start a BMW, the on-board computer reads the codes stored in the remote key. Replace dead battery in remote switch in case it can no longer unlock/lock the doors.
Car will not start if shifter is set to Reverse.
Other problems could be diagnosed using scanner.

SOURCE: Engine cranks, but does not start

My suggestion to this is to check the basics. Check fuel pressure and check spark during crank. There is no quick answer for a no start condition. You always have to start by checking the basics. An engine with no spark or fuel will not start every time.

Was this all done by a licensed repair shop ?
Have you tried moving shifter through all gears while holding key to start, just to see if any kick at all? (safety neutral switch may be faulty)

1997 bow z3 1.9 motor turns over will not start

If it got too hot the engine may have been damaged. You will need to have a cylinder compression test to make sure the engine is ok. Did the coolant get all over the engine? Some electrical connections may have gotten wet. Make sure it is getting fuel. Spray a little starter fluid into the throttle body.

1990 325i Convertible- not starting

There is probably a fuel relay somewhere in that circuit to, that may be faulty. Check your front drivers side inner fender by shock tower for 3 relays. It should be the middle one.
