1. Turn the ignition switch OFF, then disconnect the PGM-FI main relay 7P connector. 2. Check for continuity between body ground and PGM-FI main relay 7P connector terminal No. 3. YES – Go to step 3. NO – Repair open in the wire between the PGM-FI main relay and G101. 3. Measure voltage between body ground and PGM-FI main relay 7P connector terminal No. 7. Is there battery voltage? YES – Go to step 5 . NO – Go to step 4. 4. Check for a blown ACG S (15A) fuse in the underhood fuse/relay box. Is the fuse blown? YES – Repair the short in the wire between the PGM-FI main relay and the ACG S (15A) fuse. NO – Repair the open in the wire between the PGM-FI main relay and the ACG S (15A) fuse. 5. Turn the ignition switch ON (II), and measure voltage between body ground and PGM-FI main relay 7P connector terminal No. 5.

FUEL SYSTEM DESCRIPTION Fuel is drawn by the supply pump through a pre-filter screen in the tank and to the engine through the fuel supply lines. There is no lift pump in the fuel tanks or on the frame. The fuel passes through the base plate of the fuel injector control module (FICM) to cool the module. From the FICM the fuel flows to the fuel filter/heater element housing, which combines a water separator, a prime pump, a fuel heater element and a filter element. The fuel is then delivered to the high-pressure pump. An integrated hand pump is used to prime the fuel system after changing the fuel filter or servicing the fuel system. The fuel injection pump at the front of the engine valley includes the fuel supply pump and the high-pressure pump. If the fuel system is not suppling enough fuel, a driveability concern may occur. If air is being drawn into the fuel injection system, a Cranks But Will Not Run or Hart Start symptom could exist. HIGH PRESSURE SYSTEM The much larger section of the pump assembly is the high-pressure fuel injection pump. The pump is engine-driven by the camshaft gear. From the high-pressure pump, the pressurized flows to the left common fuel rail. A balance pipe from the center of the left rail then feeds the right common fuel rail. Each common fuel rail supplies one bank of 4 fuel injectors. The fuel rail pressure sensor is mounted in the middle of the right common fuel rail. RETURN SYSTEM The fuel return system routes fuel from the fuel injectors and the fuel injection pump. The fuel rail pressure relief valve is located in the rear of the left common rail. The return fuel travels to the fuel cooler and then to the fuel tank. This fuel is used to cool and lubricate the injection pump and the injectors. DIAGNOSTIC AIDS The following conditions may cause an air leak into the fuel supply system: Deformed or cut O-rings at the fuel supply line connections Improperly seated fuel supply line fittings Porous or weathered rubber fuel supply lines
