Hello Rona,

As per your first posting you don't have power to the IAC. So I checked the circuit diagram for Regina and found the RSR is the key in providing power to those items I've listed. And like rstarkie mentioned the RSR could be rejuvenated back to life (if its the culprit). The RSR is a simple robust relay only that its solder joints on the inside could get cracked and needs reflow. With a small jeweller screwdriver you could pry open the RSR at its base.

Besides the solder issue, the RSR's rubber insulation at its electrical plug could have been disintegrated over the years allowing moisture to cause some contact corrosions. These you can clean. Do have a look at these issues.

The fuel pump as you said is quite new. I'd put that aside for time being and ensure power comes to the IAC and other items first.

Amarin.
