CP3 High Pressure Fuel Injection Pump System GM- 6.6 Duramax Disconnect the fuel pressure regulator connector on the fuel injection pump. Wiring: Also see the included wiring diagram. a. Connect the wire that corresponds to pin #86 on the wiring harness to a 12V (KEY-ON) power source. b. Connect the wire that corresponds to pin #30 on. Pressure Sensor • The rail pressure sensor (Pc sensor) is attached to the rail in order to detect the fuel pressure. • It is a semiconductor type pressure sensor that utilizes the characteristics of silicon, whereby the electrical resistance changes when pressure is applied to it.. Read all Instructions before beginning!!!! Caution – EXTREME DANGER – Caution 1. Many vehicles have a “test port” fitting on the fuel rail which is used by mechanics for checking fuel pressure. This is usually covered by a black plastic cap and is where the 4an fuel feed line will be connected. Follow the wiring diagram below.
