MD Fuel pump wiring question
does anyone know if the fuel pump out put in the pfc is a negative or positive trigger and does it stay triggered as long as the car is on? i would test it but my car is in not shape for that at the moment.

Are you refering to how the ECU turns on the relay to apply power to the fuel pump, or what turns the PFC commander FP dot/light on under functions? Your question is vague.

I could use my own time to look in the wiring diagram at the end of section F of the FSM, but instead I will let you learn. Just follow the voltage through the coil. Basic DC electronics.
