If you have a pressure gage check each side of the regulator for pressure this would give you an idea which side of the fuel system is giving you problems. It could be injectors, regulator, filter or even a simple fuse to the compuvalve.

From looks of the DTC U2015, is a communiction problem indicating missing or invalide data on the SCP bus (standard Corporate protocol) "Function read vehicle speed" This information is from Jendham's Ford Quick Reference Guides printed in 2002. This is different from the information in your post

The code is definately a Ford manufacturer specific code for communications ( DTC "U" prefix). Check you wiring connections
