Abstract
A method and system for improving starting of an engine that may be repeatedly stopped and started is presented. In one example, the method adjusts a port fuel injection amount in response to engine stopping position. The engine stopping position may be indicative of a fraction of injected fuel that enters a cylinder for a first combustion event since engine stop.
