So as long as pump is running it should have voltage, regardless of engine temp? I think I know the answer but want to make sure. I also see the WUR is also connected to the O2 sensor for newer SC cars. Since my engine doesn't use O2 sensor, I wonder if that is why I'm not getting power to the WUR. Anyway, I'm surprised my car runs as well as it does without the heat element. In fact, I've been having problems with too high cold control pressure, which is opposite of what I would expect if the heating element wasn't heating. I think my recent adjustments to the WUR pin has compensated some for the lack of heating.

So....to fix this problem: I read in the manual that the power lead of the WUR should go to pin 30 of the fuel pump relay. My ground brown wire looks ok but I'm reading nothing on the red/white pwr wire. Would I have to run a separate wire all the way to the relay or can I tap into it somewhere in the engine bay?
