2003 m3 6 spd.. No start!!

Was about to go to work, and got into car and no bueno!! Car has full power (radio, headlights, windows ect. Without dimming or hesitation) when I turn the key to start I get nothing, no clicks, no failed turnovers, no wierd sound... I'm no proffesional BMW tech, but I do have some knowledge about cars and auto mechanics.. Just looking for some possible solutions..

Side note: I do hear the fuel pump kick on and prime it self...

I did do a search on it but not an in depth search since I am now late for work... First thing I'm going to try and rule out is my key, I'm gonna use my spare to rule out if my key is bad...

Suggestions please and I'll update the situation later... And I'll answer any question, cause I'll be frequently checking my post!!

Check your fuse box for the starter signal fuse. You can also try push starting since you have a manual.

Ok here's the deal, really wierd, but as soon as I got home, I put my daily driving key in to make sure, so I turn it in to the start engine position, and same thing (no start) the second I go to release it from the engine start position, it starts, so I turned off the car and pull out the key, then i put the key back in to start it and everything works fine as if nothing ever happened... Do you guys think I may have a faulty clutch pedal switch, and it acted up in the morning? Hopefully it was a fluke and a one time deal, cause it fked my morning up!!!!

You can bypass the clutch pedal switch to test it your theory or you can test the switch with a dmm.

Clutch pedal switch would be my first guess.

Sounds like clutch safety switch.Just keep needed tools and wire loop in car for if this happens again so you can get it home.

you might of enabled the immobilizer i would check the immobilizer fuse and if it happens again try unlocking locking unlocking locking and unlocking the car to disable the immobilizer then start the car. thats what happened to me and i read it somewhere on a forum forgot where. immobilizer fuse would cause the car to not turnover
