you say you have an adjustable BL WUR... Have you hooked up some CIS gauges and checked your pressures? If so, have you attempted to adjust your cold and warm control pressures?

I too have a BL WUR and used it "as shipped" for a couple of months... Started having all sorts of starting issues. then, broke down and got some CIS gauges and started checking readings. turns out that my cold control pressure was way too high [like 3.75 BAR]. When i lowered it to 2.9, the car started right up!!

hope this helps...
