If you unhooked the main fuel feed line and you aren't getting fuel, that's problem #1. I don't remember if the DSM ECU provides a trigger for the fuel pump, or actual power, but it's possible your ECU crapped out.
I remember my fuel pump signal went bad from the ECU so I had to hardwire it to the battery using ignition as a relay to turn it on. The downside of this is if you get in a crash and don't turn off the key, the fuel pump stays on, which is a safety concern. Normally if the motor shuts off unexpectedly, the ECU will also cut the fuel pump signal so you don't burn up in a gas fire.

When you say you have checked power, do you mean the plug at the top of the tank? I also had a problem on my 2g with the wires going bad so I had to replace the plug. It was intermittent and very hard to diagnose. One day it would work, and another day it wouldn't, and I had to ride in AJ's and Peter's cars on a cruise because of it.
