MY audi a4 quattro 1.8t Was running low on gas, but i put a gallon in it and when to drive it around my block. Started fine, but noticed i had a slow leak in the tire. fixed that but when i tried to start it today it wouldn't start it cranks and everything but then dies. When I try to press the gas the RPM doesn't move, and the car dies. Tried a million tires. One thing to note the crankcase breather hose has broken would that be the problem?

 

Could be. The ECU chokes the car to start it. With all that air leaking in your doing just the opposite.
