warm control pressure: no change on gauge. I did unplug the wur for the cold control reading and reconnect it with the switch on and fuel pump running to check warm control pressure.
Does it sound like a non functioning wur?

The WUR and bimetallic strip warms up over several minutes and the warm control pressure thus changes, if all is well. What is the measured resistance across the terminals?
