Power runs from through the ignition switch to Terminal 50 .
The wiring diagram shows a 3-pin connector at the injection pump: Pin 1 (Ground), Pin 2 (Signal from ECU – 0-5V), Pin 3 (Actuator power). Measure voltage between pin 3 and pin 1. You need ~5V at key-on. No voltage? Trace the wire back to ECU pin A15. A broken wire here is common. man f2000 wiring diagram
Crankshaft position, camshaft position, oil pressure, and coolant temperature sensors. Actuators: High-pressure fuel pumps and shut-off valves. 3. Lighting and Signaling Power runs from through the ignition switch to Terminal 50
