Make sure you have good power at the "switched power" lead. I think you can basically just use the power that went to the regular WUR. Not sure how the new versions are wired (I've had 3 and each had some changes in the wiring), but you also need a good tach signal, I believe, so make sure that is solid. Aside from that you just need a ground or two.

Have you checked to make sure all the various 930 relays are OK? Taking off the intercooler to set up the WUR, you could have nudged the connection to the boost shut off sensor, etc. I have had simialr symptoms (fire/no start) due to the yellow relay in the rear fender being bad and/or the boost sensor being diconnected.

Also, check your fuel pump relays.
