Ok this isnt too serious and its been happening since ive owned the car but, occasionally after my car has been driving around for a bit, ill say park somewhere and turn off the car. If i immediately start the car right after it starts and stalls, i dont hear the fuel pump come on. If say i go somewhere for a few mins (say i went to get some milk or something) come back and the car starts up like normal? Also if my car does its "stall" and i kind of rock it back a bit, or move it from where it was sitting (almost as if the tranny locks and stops it from starting) and it will start? Why would this be? Always starts cold too.
