If it cranks, you're not hydro-locked.
Well, when it comes to replacing the fuel pump, you have to drop the tank. When it comes to dropping the tank. You have to remove the rear-end. :-(
If the pump is bad, it's probably best to have a shop do the repair if you don't have air tools and adequate space.
When you remove your gas cap, are you hearing pressure release like you said, or is it a vacuum pulling air in? If it's a vacuum, that's normal. The EGR system pulls a vacuum in the tank under normal operation. (Though I don't know if that applies to just trying to start the car.) If it is, in fact, gas gurgling, it might just be because it's been sitting, and the fumes have built up pressure inside. I would guess that's also normal for a car sitting so long.
Have you tried putting fresh fuel into the tank? I would try putting at least a gallon or two of new gas, since the old may have become stagnant sitting there for over six months.
Have you checked all your fuses? With all that crazy wiring trouble, some fuses may have been blown, specifically crucial ones. I'm not sure about the third-gens, but I know in my fourth there's a second relay and fuse box under the hood as well. It could be that your fuel or ignition system (injectors, ECM, etc.) Has a blown fuse, or that your fuel pump's relay (if your car has one) is dead. If possible, try trading your fuel pump relay for another in the box, say the air pump or air conditioning, whatever fits. Try starting it then. If it does, and your fuses are all good, the relay is the issue.
If you can, crawl under the car and check the fuel lines that travel along the bottom of the body beneath the driver side. One may be crushed, if the car's been ran over something.
