1997 Ford Ranger Fuel Pump Wiring Diagram
The 1997 Ford Ranger fuel pump wiring diagram is a complex system that involves several components. Below is a detailed description of the wiring diagram:
| Wire Color | Circuit Function | Wire Gauge | Connector Part Number |
|---|---|---|---|
| Pink/Black | Fuel Pump Power Supply | 12 Gauge | Black 4-Way C158 |
| Red | Fuel Pump Relay Switch to Fuel Pump | 18 Gauge | Green 6-Way C101 |
| Yellow/Black | Fuel Pump Inertia Switch to Fuel Pump | 18 Gauge | Gray C270 |
| Black/Pink | Fuel Pump Ground | 12 Gauge | Black 4-Way C158 |
Pink/Black Wire
The pink/black wire is responsible for supplying power to the fuel pump. It is connected to the black 4-way connector C158. The power is supplied when the ignition is turned on. If there is a problem with this wire, the fuel pump will not receive power and will not function.
Red Wire
The red wire is connected to the fuel pump relay switch. When the fuel pump relay switch is closed, the red wire sends power to the fuel pump. The red wire is connected to the green 6-way connector C101. If there is a problem with this wire, the fuel pump will not receive power from the relay switch.
Yellow/Black Wire
The yellow/black wire is connected to the fuel pump inertia switch. If the vehicle is involved in an accident or is jolted, the fuel pump inertia switch will shut off the fuel pump. The yellow/black wire is responsible for reconnecting the fuel pump when the switch is reset. The wire is connected to the gray connector C270. If there is a problem with this wire, the fuel pump may not receive power after the inertia switch has been reset.
Black/Pink Wire
The black/pink wire is responsible for grounding the fuel pump. It is connected to the black 4-way connector C158. The grounding system is an important part of the fuel pump wiring system. If there is a problem with this wire, the fuel pump may not function properly.
