Agree with Ken 100%. Pull a plug to look at the burn, and verify that you have power to the WUR (same circuit as the rear fuel pump). If no power, then blown fuse (which would also take out your rear pump, dropping system pressure and causing low control pressure at the WUR = rich running. The WUR won't warm up properly and be stuck in warmup mode.
If all is good then proceed to checking pressures for which you'll need the gauge setup. A good place to start for ruling out fueling.
