Re: HFS-3 not spraying
OK, so ECU cable on good. I?ve checked all the wire colours and they all have the same orientation red, yellow, blue, black. I do have multimeter.
Is it a must for the thin red wire to be connected to injector (+) or does it matter if the connetion just have 12V in pre-crank position (and when the car is running of course). If I?ve understood correctly both red wires need to get 12V in pre-crank position but where ever I put the thin red the pump activates when the gauge lights up. I don?t understand what triggers the system to spray when the car is not even running. Is it possible that the injector is "short to ground" for some reason in pre-crank position.
Well either way the system will not spray when the car is running.
