Yesterday and today I went out to start my car, at first it didnt start but finaly started after the second crank. However, when i went to give it gas the car just dies. It doesnt even attempt to rev up, just completly dies out. If i start the car and let it Idle for about a minute or so i can then give it gas and it drives fine after that.. any ideas what would cause it to die when i give it gas?
