Cadillac Repair: 91 cadillac sedan deville showing D, volt amp, cadillac sedan deville

Question
 I was looking at the site and came across the question ive been looking for an answer for and i kind of got it...I am having a "d" show up in the digital readings of where my miles until empty and air control is...I was reading a response to a previous question asked and i was wondering how you switch the FDC and ECC connectors and where are they located?

Answer
Switching the FDC and ECC connectors has NOTHING to do with the "D: displaying in the fuel display.

What you have is a problem with the computer and you need to perform some simple tests if you know how to use a DIGITAL VOLT/AMP meter.
