I have a 1995 Q45 that's having fuel issues concerning the fuel module. I read a post about running a temporary by- pass to the pump, but I'm not much of a mechanic and I need pictures to show me exactly what to do. Anybody know of a post or site that will show me what to do?

From the trunk remove the rear panel in front of the fuel tank and you'll see the FPCU mounted under the parcel shelf on the right side. You can see the FPCU in the background in the pic. Unplug the connector, orient it as shown in the pic, and run a jumper from the pin shown to an unpainted surface (i.e., the frame in front of the gas tank). The fuel pump will only run on high speed but it will quickly tell you if there's a problem with the FPCU.
