I suspect an Intake Air Temperature is faulty...seeing the atmosphere as much cooler than it is and puttin' more juice in that~ this combined with the engine temperature sensor will provide sufficient data to get your mix right...check both of these sensors....will post links to them if you do not want to do your own shopping~

....okay datburn link don't work so here's a screenshot of the IAT~shucks~


What do you mean when you say it floods out? Does it just keep cranking but won't actually start? The fuel tank in the Q45 is between the backs of the rear seats and the inner wall of the trunk. If you can either remove the seat backs or remove the carpetted wall in trunk to get to the fuel tank. Have someone else try starting it while at the same time you sternly tap the tank with a rubber mallet or jack handle. Not sure if this will work as the fuel tank is vertical instead of horizontal as in most cars but if the fuel pump is clogged or stuck in some way, the tapping can sometimes get it going at least until the next time you shut it off. This will help identify if the fuel pump is bad so when you get it fixed you aren't paying a shop money out the ears to replace things that aren't causing the problem. Since running out of fuel seemingly caused the problem, naturally the fuel system should be where you check first.
