So was just looking at 2007 2.3l Ranger wiring diagram
To my surprise the fuel injectors don't get 12volts from PCM relay anymore, they get it from Fuel Pump relay
Diagram below
In Previous years the FP relay was only activated for 2 seconds key on and then wouldn't activate again until engine started(above 400rpm)
Obviously that wouldn't work out to well if injectors were powered by fuel pump relay, lol
So I guess FP relay now activates when cranking engine over
Just a heads up for diagnosing a No Start
