Weird Electrical Problem!

I crunk the car up at buddy's house with a small lawnmower battery and drove the car onto the trailer. I drove it around a couple of days and had a couple of problems starting it (egi relay started buzzing). I snatched the motor, rebuilt it, and go to put it in the car, and no fuel. Also, no spark. I got all the grounds situated and started getting fuel to the rail, so I tried to crank it, and it started and ran momentarily. Then I did the same thing a second time and it died right after I started it. Then it wouldnt start at all. It's like the starter would barely turn the flywheel and was sticking open...had to turn the crank by hand to free it. I thought the motor was vapor locked so I took the plugs out and turned it by hand to free it up. I left the plugs out and tried turning it over again with the starter and it did the same thing.

I removed the starter, grounded it and sent power to it and it seemed to be great. I still took it to advance auto to get them to check it and they said it seemed fine. But neither test was under load, so idk. It just puzzles me because it started the car twice.

I plan on redoing the pos+ and neg- batter wires tomorrow. Maybe it's not getting enough power to the starter. I know I'm getting fire to the knock sensor, cas, and ignitor chipnd daily drive it.

so i recently bought a 1990 240sx and when i bought it the guy said he thought the neutral safety switch was going out cause you would have to push the clutch in a couple times in order to get it to turn over and start. well once i got it home it sat for a couple of days and when i went to start it, it was being difficult and was doing what the guy said it was doing to him. And i got it to start then turned it off and tried later that week and then it wouldn't start at all and for a day or 2 the power was completely gone when i turned the key and then it stopped doing that. so i replaced the neutral safety switch and it still wouldn't start, then the battery still nothing, then the alternator, and the starter and still no start, so as of right now it clicks when i turn the key but it won't start. And i can by pass and get the car to turn over at the starter and then have someone inside the car turn the key to get it to start. And i haven't messed with the starter relay. and if i remember correctly the ground is fine and isn't to corroded. Please help its probably something simple and stupid. Thanks for your time!
