Re: Pump is activated after a while when the motor is not running
I don't know, there shouldn't be. But I measured the lines, and there is very big resistance from the injector to the ECU connector pin 3. It should be straight wire according to schematics. I also measured from the other S4, and it is the same. Very strange. I have to find out the correct year schematics to be sure about the connections.
I measured the voltages again, and it is 3.5 V measured against the ground (on both injector pins). Previously I did it against the "+", and that was the ~9 V.
So I guess that if I change the HFS-3 red wire to something that has 12 V, that doesn't change the situation since the injector "-" has that 3.5 V?
