99 audi a4 1.8t wont start
 

So my audi usually starts rough on cold morning but i tap the gas and it starts right up, this morning i wasnt in the seat and couldnt hit the gas so it died and no refuses to stary.

It cranks but doesnt turn over i already replaced the feul filter and the i can hear the feul pump turn on, brand new spark plugs and still nothing.

Any ideas?
