If you saying the pump runs as soon as the battery is connected but with the key off, then it sounds like the CAT sourced T2 is configured for pump control but is miswired for power to the ecu or the pump. If the T2 had power all the time I expect you would not be able to shut it off with the key (ignition stays on as well). I'd pull the pump relay and see if the pump still runs and do the same with just the fuse pulled. If it stops, trace from the relay to power and ground on the relay control terminals. The fuse socket should not be shorted to more than one terminal of the relay socket. 

Maybe I misspoke, the pump cycles when the power (IE: cut off) is turned on, but kicks off 5-10 seconds later, car turns off normally with the regular key. Pump does not continuously run. I'll start with the basics you laid out hopefully next week, once all the parts have arrived (tuesday/wednesday time frame)..Until then the car remains stagnant, unless I get motivated to do the oil and oil filter before then.

Just a quick update as I had an hour of free time this early afternoon and I'm proud to say the original Delphi FF52 fuel filter, with it's June 2002 date code has now been excised from the car. Both the previously mentioned  Fram G3727 and the ACDelco GF952 are within a 1/16th of an inch difference in length, I decided on the FRAM G3727 as it appears to be a better built unit of the two, I'll hold on to the other just so I have a back up in the garage. Pressurized the system found no leaks, and fired the car up on the second turn of the key. I'm now waiting on the new Motorcraft SP463 Plugs to be gaped at .050 per Tom (1turbofocus) the high impedance 30lb/hr injectors, and the MSD coil and wire set. If I get time tomorrow I'll do the oil and oil filter change while I wait for everything else to arrive...Then dive in to the rest in short order and hopefully be able to take the car around the block and further.

 

Thanks to all who have assisted so far.
