My car doesn't seem to start., Please Help Options

Hey guys, I've been trying to figure out why my car won't start for a few days now. I first came to realize it had a problem when I was driving in on the freeway and made my way to the lane right of me. When I did that the car just shut off completely lights and all. Tried turning it back on nothing. Open the hood and realized the battery cablel was loose and since I was close to my house already and didn't have tools to tighten it I just put it back and it turned on and drove off. Left it parked.

Next day I decide to take it out, I opened all the windows and sunroof (since it was hot) and open the hood to tighten the battery down and thats where the problems started. I tighten it fully but it wouldn't start nor would any lights go on (dash board or any lights). But if I would turn the negative cable to a certain side you would hear things go on. If i tighten it, it would go back to sending no current. You would only hear things go back on if i held onto the cable at that exact angle, if i slightly moved it, nothing would happen. And when I tighten it at one point it threw a whole bunch of sparks.

So here's the deal, I need to move this car, and all my windows are stuck open.

I have changed -

- Battery Terminals
-Fuses 100a, 60a, and either a 50a or a 40a. ( don't remember what they are right now, but i know one was for the alternator)
- Checked the other fuses and all seemed good
-Battery is new, and I tested the battery of another car as well and no luck

What should I check now? Are there any fuses that I might have skipped over and should double check? Could it be the alternator? Maybe the cables have gone bad?

Please help guys, I've tried the best I can but I know very little about this sort of stuff. Thank you ahead of time and appreciated.

and if it helps at all, I drive an 96 ST model.

your car turned back on, i was going to say timing belt - still could be if it eventually broke, open the cover and check.

can't be alternator preventing it, if you have a new battery, it would turn on regardless. I mean eventually it would drain if the alternator was bad but not prevent it from starting.

check fuel delivery and ignition spark, distributor, etc., some other thing in the tail end is the computer box. but thats something for later after you check these things. its gonna get complicated if there are serious electrical issues
