Abstract: Vehicles and engines are provided. The engine, for example, may include a first engine component configured to be ohmically coupled to a common ground, a second engine component configured to be coupled to the first engine component, the second engine component comprising an insulative materially ohmically isolating the second engine component from the first engine component, the second engine component including an inclusion having a predetermined depth along a surface of the second engine component configured to be coupled to the first engine component, a third engine component configured to be coupled to the second engine component, and a spring clip configured to be ohmically coupled to the third engine component, wherein the spring clip is further configured to be disposed within the inclusion of the second engine component and to have a deflectable surface having an undeflected depth greater than the predetermined depth of the inclusion.

Abstract: An engine fuel delivery system includes a fuel pump having a pumping chamber to increase fuel pressure and a closeable inlet valve, and a fuel rail to communicate pressurized fuel received from the fuel pump to at least one engine cylinder. The engine fuel delivery system also includes a controller programmed to issue a control signal to periodically close the inlet valve to generate a setpoint fuel pressure within the pumping chamber. The controller is also programmed to adjust a control signal gain value in response to deviation in an outlet fuel pressure relative to the setpoint fuel pressure. The controller is further programmed to issue a warning message in response to the control signal gain being adjusted by more than a predetermined threshold from a calibrated gain value.
