this, unless its one of the little motors that require proper backpressure to run at all...

I agree.
If u cannot hear a hum when u turn the key to "ON" (not start), then the fuel pump is not priming.
When u turn your key to "on", the fuel pump primes the gas line for the engine to use. Every car does this.
Neext time, have your wife turn your key to "on" and listen right near the gas tank. U should hear a electrical humming/buzzing sound. Thats the fuel pump priming.

So did you figure out what's wrong with the car yet? Show us a picture of it too.

The umbrella wouldn't really help. It's Houston, you can't hide from the heat by just being in shade.

Fuel system somewhere. Didn't get into a lot of testing because we had to get the car turned around so it was easier to jump, which meant pushing it up hill and through grass and stuff which was ridiculous.. Completely drained me of energy. Was raining here until just a little bit ago too.
Anyways, I undid the battery again, did what I read resets the ECM/PCM or whatever you wanna call it, and reconnected it. Then made sure to follow procedure that wouldn't lock me out (when I put the battery in I had the door unlocked already, this time I made sure it was locked and unlocked it after the battery was connected, just in case) No stray wires anywhere I could see. Tried starting it up, still same problem. Removed airbox tried starting, same problem. Sprayed in starter fluid, and it tried to start. I still don't hear a fuel pump and I looked in the fuse box in the engine compartment but didn't see anything there related to the fuel system (going by the diagram on the lid to the fuse box) so I'm going to need to look at some fuse diagrams and figure out which ones to check.

I would replaces all the fuses. It's a pain in the ass to get a checker and check all of them. 5$ fix and you can eliminate that as a prob

i need your fuse connection $5 for a set of fuses.
protip tho, if you have the kind of junkyard where you pull your own parts pay $1 to get in the yard or whatever they charge and fill your pockets with fuses and relays

Yeah I'm not just gonna go out and buy all new fuses. I can test them. Takes just a few seconds longer than it would to pull them out and flat out replace them.

Beat me to the punch. Sometimes junkyards will have an 'all you can carry' sale and I've beaten that game by cutting a roof liner out and using it as a bag like santa clause... thems the rules mang

If u put starter fluid in the intake and tried to start up, then its definitely the fuel pump.
Check for a fuse box in both the glovebox, under the steering wheel, and under the hood. Cars usually have two fuse boxes, one for relaying and one for direct power.
If u havent already, get a repair manual from the auto store. It likely has fuse laayouts specifically for your car.
And if its the fuel pump thats bad, it will tell u how to remove it.

Well generally I do, but I read that Haynes neglected to make one for our car. I've been using this: http://www.mazdaspd.com/manuals.html#ENG
I've already looked up a video of someone replacing the fuel pump on my car, because I wanted to know how bad it was going to be. Hope I don't go and find something different, but we apparently have access to it through the floor panel. So it's really just a matter of like 8 screws and lifting the whole fuel sending unit out, no need to drop the tank or anything. (REALLY hope this is the case).
I know there is more than one fuse panel, but I'll need a diagram. I only started to check the one in the engine compartment because it was right there and the diagram was right there. It was getting late by the time I found out it tried to start with starter fluid.
Whatever the reason for it, I highly suspect this isn't a case of restricted lines/filters and is actually just the fuel pump not sending fuel at all. So I'm gonna focus on seeing if I can figure out why. But like Enlil mentioned earlier, it may not be fuses or even the pump itself. It could be some error with the PCM. I would think if that was the problem, then the PCM would be refusing to send power to the pump, so if I determine it's not a fuse issue, I'm gonna check the connector to see if it's getting voltage to the fuel sending unit.
The thing that bugs me the most about this is it started just fine on 2 separate days, and then suddenly as soon as the battery is disconnected, there's a problem. Just feel that has to be strongly related to what is going on somehow (it'd be a huge coincidence otherwise, which isn't impossible, but is kind of improbable) but I can't determine why or how. I know for a fact I never crossed the wires or shorted anything out.
Pointless but funny edit: I called Enlil "Burke" and didn't catch it til the next day

sounds like you know what youre doing 
I hear u on the coincidence.
My fuel pump starting acting up *right* after some punk ass kid robbed my car and took my amp/sub. I was convinced he put sugar in my tank or pissed in it or something.
Turns out, it was just a coincidence, no sugar or sabotage to the tank.
Glad your fuel pump is easy to get to. Get that voltage meter on that pump connector when the key is ON and see what happens....

Also, to test the fuel pump, just dunk it into a bucket of fuel and hook it up to 12v and see if it pumps. Of course be very very cautious not to make any sparks! Better connect it to 12v first and make sure the connection is good, then dunk it.

If you sprayed starter fluid in the manifold properly and it still didn't start it is not a fuel pump issue..
And some of you give really horrible advice when it comes to repairing vehicles.. My suggestion is stop giving advice if you have zero idea what you are talking about

I'll gladly stand corrected if I say something stupid, feel free to point out where I go wrong and what a better approach would be. I think that is more useful to everyone than being so unspecific.

I think you misread him. He said that with the starter fluid, it "tried to start". That is a definite improvement over what he had before. It also suggests that compression and spark are there.

I don't know if he was talking about you, but I will say that dunking a fuel pump won't necessarily tell him if it's bad. This is an injected car, so pressures need to be high. A pump will often pump with no resistance, but fail to provide pressure sufficient to make injectors work.
He can check pressure from the rail bleeder, but I doubt he's got the tools.

Good point Enlil. I've heard of people testing how far the pump will jet a stream of fuel to estimate it's effectiveness, but it doesn't sound accurate to me and quite messy too.
