Abstract

A method for starting an engine is provided. The method comprises opening a throttle valve controlling air flow into an intake manifold in response to a gaseous pressure differential across a gaseous fuel injector exceeding a threshold pressure. In this way, delayed engine starts using gaseous fuel may be mitigated.
