I'm not sure if the SC has a DME relay like my 88 does, but if so you can test the fuel pump by jumpering two pins on the DME relay socket. This puts 12v directly to the pump with the engine off. If you hear nothing, the pump or wiring is bad. When this happened to me, giving the pump a whack when power was applied caused it to run for a second and then stop again. That was the smoking gun I needed. The details of this are in the Bentley manual.
