Recently bout 2008 750i(sports package) with 185k on it.
I have turned the car off at gas stations.
Sometimes the car would crank and no start or sometimes it would just Come on and make clicking noise and starter would not engage.
Then if I let it sit sit for amout of time it would start up sometimes goes hours with out starting or doing NOTHING.
i got the car around January in the problem I'm explaining has been the same exact issue everytime it happens.
Some occasion I would have to car towed and 1 time after 10 minutes of it being towed from gas station bout half a mile down the road to my dad's shop. It started right up.
Last time I drove it I drove it to a destination around 70 miles away when I get to store and turn car off and came back out it does the crank no start thingy again so I kept trying to start it nothing at all it would crank but wouldn't start up and sometimes it wouldn't even crank all I heard was clicking noises even had jumper cables plugged to front terminals while trying still nothing at all.
So after trying for a few hours still nothing car sit overnight at store come back to try it the next day same thing.So I had it towed home and been doing the same things since then and all this had been bout 3-4 weeks ago RECENTLY
So far I have replaced battery n alternator (2months ago)
Also replaced Crank shaft position sensor,fuel pump,and also fuel filter.STILL CRANK NO START.
I ALSO HAVE A PEICE OF PAPERS OF CODE'S THAT HAVE CAME BACK.
ANY HELP WOULD BE GREAT..THANKS

Sometimes when those sort of things happen you may want to look at your IVM (integrated voltage module) as the issue. Thay have history of causing no crank, no start conditions when cranking, and just an engine running like crap. The module contains fuses and relays for other computers in the that control the engine. They also have a history of bad solder joints over time causing an internittent electrical issue. You can search this forum as it has been mentioned before and there not expensive for new.

This is not a solution but I have a similar problem (although not lately) with my 2008 750Li with 228 K miles. I replaced battery (registered) and alternator. One mystery I haven't solved is why the CCAs at the battery (900ish) and at the engine bay terminal are so different (350ish). Voltage is a few tenths V. less too. Again, not a solution, but maybe something for you to check.
