Abstract
An engine system and a method of starting an internal combustion engine of the engine system are described. In one embodiment, the method includes adjusting a fuel pressure within a fuel rail to exceed a pressure of a pressure relief valve. The method may be particularly useful during degradation of a fuel pressure sensor.
