OMG car wont start. just spent 3 hours replacing the starter. still wont start. the car is in park but still rolls. i need to use the e brake to hold it from rolling while in park. WTF

I think there is a fuse to the electric fuel pump. Check that. A computer module may have gone out and it affects if there is spark at the plugs. When you turn on the car, do you hear the electric fuel pump engage? Since your in a parking lot, it may be best to have it towed to a reliable garage that works on your model of car. They can pull the plugs and check if there is a current going to the spark plugs, also check if there is fuel in the rails or injectors. Since your turning over the car motor without starting, check if there is raw fuel smell in the tail pipe as it may be pumping the fuel/fumes out if there is gas getting into the cylinders. This works on pre-catalytic cars.
