Could probably still do with a 'tune-up' of the K-Jet, but now I can just jump in the car and start it, hassle free.
I installed a junction box to gracefully simplify some of the ugly aftermarket stereo wiring also, and ran the wire for the fuel pump power from that junction box also. It doesn't look factory but it is a bit neater. Maybe I could have just run it off of one of the bridged terminals on the fuse box, but I was hesitant to put another 6amps through a system that I know nothing about, particularly on a model of car where electrical fires seem to be commonplace.
I still can't figure out how the hell it ever worked before the problem developed, it seems that it was simply wired up incorrectly, but it isn't something that I have ever changed.
I really want to say thanks for all of the feedback that you guys provided. Working through problems like this can be a challenge so I hope I didn't come off as unappreciative.

Glad you got it working.
Now that you have installed a relay, was it a 5 pin relay? If so, I might suggest you go one step further and wire the relay to the air flow sensor switch that is on you 3.0 liter engine. This is a safety precaution that will shut off the pump if the engine dies while the ignition switch is in the "run" position.
If you are interested in adding this safety feature, let us know and we can explain how to do it as it is a relatively easy addition since your engine already has the sensor switch.
