hi there to all us audi fans, this is my first post so i'm new to this.

Can anyone help me with this slight problem that my car wont start!
A couple of times over the past couple of weeks the car hasn't started at 1st attempt and has taken a good few turns to get goin. It does it when its cold and when its hot. I changed the plugs to begin with as the used ones didnt look the best, but when i came to start it up after the plug change, it wouldn't go, it was turning over just not firing up. So changed the plugs back to the old ones, and still no good. Have checked the spark and its a good spark (with the old plugs). their seems to be petrol coming through as the plugs are moist at the electrode tip, but they are not wet!! how much petrol should there be on the plugs? and would the engine management restrict the flow to prevent flooding?
Or is it a sensor problem? Would this affect the starting up? crank sensor, camshaft sensor, temp sensor???!!

any help would be much appreciated
