No starter operation engine is not turning over?

There is no battery drain - both the battery and the alternator are doing fine. Problem is that when I put the key in the ignition and crank, nothing happens.

Once I have started the car using a jump, the "repair" is good for the day, but next morning, an attempt to start again is without success. There is no life - no lights on the dash, no cranking of the engine, absolutely nothing. A quick jump brings everything back to good and remains that way for the day, but a repeat of the problem occurs the following mornng.

The battery is NOT going flat! The battery and the alternator are fine. When parked overnight, the next morning when starting is attempted, nothing is happening. No lights/no crank/no nothing. The battery is testing fully charged, the alternator is putting out well, and when restart is attempted on the same day, nothing is a problem. Next morning though, nothing at all.
Battery cables are clean and well attached.

You are asking to evaluate but I am only stating the facts. Yes, the battery is fine and yes a jump works to get it started. I am trying to determine the problem and find a solution. These are facts.
The battery cables appear to have no problem (checked both by me and Sears), and if that is the case, what would cause this scenario?

The battery is fine and alternator output is fine as confirmed by testing at Sears. Do the dash lights come on when cables attached? Don't know that answer - simply did not observe when I jumped the vehicle.
The key was not in the on position when the cables were attached, and when I got into the car to start, it immediately cranked with the key. And as I said, once started, I had no further problem that day. The problem recurred the next morning, indicating no resolutin was found.

Of course I have no means to check the battery in the morning as I lack any such test equipment. However, the likelyhood of my starting the car with a jump and fully recharging causes me doubt. The drive to Sears is less than 3 miles and less than 10 minutes.
I don't know that what you are suggesting so far is addressing the issue, but I can see if there is anything that might be draining the battery. The only thing that comes to mind is a roof light that has never worked well, and I did recently place a bulb in there even though it did not correct the roof light.
Any other suggestions?

Ok. Here goes.I posted up a question about a month ago and alas the car is still not working :) I definitely appreciated the answers and the input which is why im asking again.

My battery is fully charged.I had the car when it was running tested at autozone(the starter and ignition test) and the person who ran the test informed me that everything was working fine.

Several weeks later, my car just wouldn't start. My roomate suggested to try jumping it. So we did. And it started.

Several days later, the car was just dead again. I put the key in, all the dash lights come on, but as soon as I turn the key it just goes click, and all my dash lights go off, I lose all power.

So we tried to jump it again. We sat there for about a half hour letting the battery get a charge, thinking it was dead. Tried to start it and alls I was hearing was just a very fast clicking sound, like the car wanted to turn over but it just didnt have enough juice to do so.

For shits and giggles I had the battery tested again, battery was still good. My car has been sitting in the same parking spot at my apartment and im very scared some ass hat is gonna tow it but thats another matter.
I dont know what else to do.

I know there was an anti theft system in it when I purchased the car from some dude. That was causing the car to not start sometimes. But after I unplugged the anti theft, it ran fine for a while. Now something is just draining my power some where and I cant get it to start.

In the lower left hand kick panel, in the fuses, there is a square black plug which says relay on it. When I turn the key I would get like a clicking or a popping sound from it.

I know nothing about wiring.I've downloaded every wiring diagram on 93 celicas that I can get my hands on. Im also thinking maybe the ignition switch? But I think the bottom line is the person who installed the anti theft didnt know what the hell he was doing and seriously messed up my wiring.

Any ideas? Id appreciate some feed back. If you read through this whole thing? I appreciate it even more. Just trying to be as descriptive as I can

thanks again

Thanks for the input. :) I believe im going to go attempt that now:)

If its a bad ground cable is it just one cable can I ask? Or is it a series of wires? Im horrible at electrical.
And is it also costly to fix?

Hey back again :) I tried jumping it with one hooked up to the negative the other hooked to a spot on the engine. No start.
I removed the negative terminal cable, un bolted it. Im gonna try replacing it, hoping that works

Yeah battery voltage was in the optimal range
