after more investigations:

there is NO pressure in the fuel rail and the fuel pump doesn't run either (I can't hear any noise and I put a stethoscope (sp?) on the fuel tank, no noise there.

so, even if the fuel filter is plugged, I should hear a little something, unless it's jammed solid

I'm not sure if the pump can just die of not running, so I'm leaning toward wires corroded or something like that...

what fuse drives the pump? (is it the PCM bat?) looks like they're all good, but I want to check if there's anything at the fuse socket.

Which way the wires go? I have the reference manuals in storage

also, there's a wire that doesn't look very good (sitting too close to the headers) and I forgot what is where on that car on the passenger side, next to the last cylinder? I guess it has nothing to do with it though.

any more ideas before I get the car towed to a store? can't use a jack in the storage lot...

Easiest method if you cant use a jack in the lot is to just cut a hole in the back seat area of your car and replace the fuel pump/check the wires.

Here is a picture of where I cut mine out. I sprayed rhino liner on the inside so its harder to make out, but its in the center of that picture where the hump is.

check the fuel pump relay, then check the wiring for corrosion, and if the relay and wiring are good, change the pump.

I have it down to a science.

1) Jack car up
2) Remove passenger side wheel
3) Remove UPHR, PHR,
4) Disconnect muffler from Y-pipe (I have long tubes) slide to the side
5) remove heat shields
6) Disconnect passenger side shock
7) Remove gas cap and cap shroud
8) Jump the fuel pump to drain the tank or siphon if its dead
9) Unbolt tank straps slide out tank.
10) Remove fuel pump, rinse out tank
11) Reinstall everything.

This is the way it should be done

As with others I'm going to agree the gas has NOT gone bad. I let me car sit for a year and I connected the battery and it started right up. Lately I just exercise it once every few weeks as it's "off the road" for the time being. It's been almost two years since I filled up that car (still have a receipt in the cupholder for a 93 octane fill up at $1.35/gallon) and it runs just fine on the gas.
