Re: Help please,HFS 4 V3 wiring diagram for E63 AMG
Thanks Richard ,
You mean , we only wire red and green wites to the fuel injector without using map sensor signal , right ?
The pump is working when I start the system with the buton on the gauge ,
I hear the sound of working pump but it doesn't inject any liquid , the pump only works. I don't know what triggers to work.
