My BMW Wont Start Any Ideas Plz Help!!

[got2have]

Hey Guys i was so pissed had to be at work at certain time so i get out to warm up my 2006 E60 530 and it wont start.

I tried everything possible i can think off
1) boosting the battery with jumper cables & boosting packs
2) different ignition key and nothing helps to get the car started.

So i went to my mechanic he said it shouldn't be a Starter since my car is fairly new and it has ony 70k on it and i am the original owner always well maintained, oil change, fluids change and etc. I Checked battery connectors and the battery fluid indicator still has the green light on (meaning it has charge)One thing i recall doing often is sitting in the car and listening to my radio while the car was off. Could i have damaged anything by doing this often or maybe completely killing the battery itself. I had a battery emblem light up in the computer few weeks ago when i was sitting in the car, but it all went off. All the lights go on when i turn key even the navi works, interior lights but the car refuses to start. Please Help if you have any ideas or recommendations.

I really doubt playing the radio with the engine shut down played any role; surely the jump start would get past that. I think there may be an electric fault that needs sorting.

Does it turn over? but not kick in?
if so:
Check the fuel pump fuze( (mines above the battery)

If it doesn't turn over, then maybe you've a bad earth to/from the starter
or if it's an auto, the gearbox, P/N position isn't being detected by the EMS so it won't allow it to start.

Camshaft sensor also controls the fuel pump power

for what it's worth....

CRANKshaft sensor controls the fuel pump the CAMshaft sensor controls the injection system amongst other things.

I think I may have the same problem

I have an E34 530 and an E28 M535i and both do exactly the same thing!
Key just turns around....won't even crank over...but everything else works. Leave it a little while and will eventually start again. Both are perfect when running tho...

From what I can find to date it could be either:
-Relay
-Crankshaft sensors

I'm trying to determine the fault too...very frustrating!

If it eventually starts after a while and does this all the time its not down to the crankshaft sensor.

Do you leave the key in the ignition before it will start? If so it could be a faulty key (alarm fob)?

It doesn't seem to matter which key I use.... but you're right it's almost like the car is immobilised. I have tried disconnecting the negative battery terminal on the car and reconnecting...sometimes this has helped, but sometime makes no difference.....
