Fuel is supplied at high pressure to the injectors via fuel rail which incorporates a fuel pressure and a fuel temperature sensor. The ECM increases the
fuel pressure to minimize fuel vapor formation to maintain fuel flow across the injectors. An inertia type fuel cut-off switch will cut power to the fuel
pump module in the event of an accident.
