as titled really, after some help;

happens exactly as video, cranks but will not start, fault code scanner cannot connect so assume ecu / electrical problem somewhere?

Has any had this problem or knows the fix?

Strange video that. Couldn't hear it cranking and does the rev needle not move when cranking?

Anyway, I had a similar problem. Can try squirting that easy start into intake, if that ignites then u know no fuel is getting to engine. This then suggests fuel pump or pump fuse. I suppose a physical blockage could also be to blame but much less likely.

forgot to say my dash looks the same but does actually crank over.

will check all fuses etc when its light

Mine played up the otherday.. Have a look on some BMW forums and you'll see a lot of posts about starting problems with e46's lots of different reasons etc

I used my spare key and it works perfectly so is a little odd? Strange little niggle that I don't really understand fully yet

U mustve got thus sorted by now. What was the problem?

[MrWhale]

Late reply sorry.

Had a proper look in the daylight and the fuse for the DME had blown so wasn't communicating with Dash etc, all sorted now

No use for the OP but maybe for others experiencing similar issues.

A common fault with similar symptoms is the crank or camshaft sensors going awol.

Essentially the faulty sensor stops reporting position information and the ECU assuming the worst inhibits fuel supply to prevent the engine starting. I had this with an early 330d and no-one could identify the fault, took a long time with multiple visits to BMW and specialists. Turned out the early software didn't log these faults and even the newer software cleared them after one successful start.
