Hmm, I did not disconnect the wur power when I measured the cold pressure. with everything warmed up I got exactly 3.75 on the control pressure warm which is the figure listed in the manual. my system pressure was slightly low at 6.6 the book calls for 6.7 to 7.4. control pressure delivery was within spec at 230. manual calls for 160 to 240 cc/min. however, warm throttle enrichment with warm engine and wur pressurized at .5 bar did not cause my 3.75 warm pressure to move at all. recorded 26 ohms resistance at the wur, can't seem to get a voltage off of the power wire to the wur, should that not be battery voltage with ignition on and pumps running? thanks again for the help guys.
