battery? Alternator? wiring harness/ECU all ok? Coils replaced? Plugs seated correctly? Start small and work your way up.

this was satisfying, before i found out it wouldn't start..
There was a good thing about this weekend though. The dealership here, which had previously proved to be worthless, actually helped me on Friday. I went in after work to see if they could show me some part diagrams to help me put the hoses back in the right place, and they let me borrow these! Didn't ask for my name or a deposit or anything.. going to make some PDFs before I return them. I had the engine manual, but not the other ones.
I'll be towing it somewhere tonight to see if they can figure out my electrical problem.
Battery, fuses, alternator, are all okay. Plugs are fine and are getting fuel. It turns over, it just doesn't fire up, so somewhere along the way I did something to make it so I don't have spark. I called a shop around here and they said it could be a bad sensor. Maybe I broke something when pulling things off, very possible.
edit: I'm not sure if cam position sensors will cause the car not to start. On the LGT they just made the car run rough when they started to go out. Also, they are a PITA to get to.

I just read your whole post instead of working!
Damn you are so close!
Is your ECU showing any issues or wont it log anything unless it runs?
You go girl!!!!
When I took it apart, I noticed that a sensor on the top of the block, toward the transmission, looked like it had pretty corroded connections. I tried to clean it up the best I could and I reused it, since I didn't have a problem with it before. Maybe I messed it up. Anyone know what that sensor is? It's by itself, and bolts directly into the top of the block near the center by the transmission. It has its own plug and plugs into the harness that comes off with the intake manifold if I remember correctly. Its like black plastic, it's round, and it has a hole in the center that a bolt goes through. The inside of the hole is metal, which seems like the sensor/electric contact part. Sorry if my description is not the best...
This is going to sound a little dumb.. but.. check all the grounds?

SUCH IS MANGO!
I did check all the grounds. I was hoping it was something dumb like that. I even took all the grounds back off, filed the connections, and put them all back on. Did not help, but worth a try.
It's the home stretch! I'm somewhat amazed at how quickly you've gotten this done. Pretty sure if it were me, I'd still me at the cleaning phase... (I'm a measure 4 times, cut once kind of guy.)
answering my own question... the thing is the knock sensor i think. can that give me a no-start situation?
The knock sensor wont. The crank sensor will.
It's super common for people to forget the crank sensor while putting everything back together. (Did it myself...)
If you remove the alternator, there will be 2 plugs that you have to plug back in that lie under it.... one of them is the crank sensor
