When I had the engine in I tried starting it and there was this horrible clank sound as it tried to turn over.

NOt trying to hijack your thread,
but this is happening to my car. what is it? car wont start?

So my car turned but didn't start. while it turned there was a loud clank on the side of the engine next to the starter. Now the engine wont turn. It's not the starter. took it out, tested and was still good. Want to know what it might to see if it's worth fixing.
Any help will be greatly appreciated.
Thanks in advance.

torque converter or flywheel issue maybe? dont hold me to it but maybe try turning the crank by hand and give it another shot, maybe you hit a flat spot in the flywheel, that or a wire came off and grounded on the block, makin that noise

I had a similar issue, turned out the clutch fork pivot broke and the fork dropped and bound up. Try turning it over by hand, in BOTH directions.

It's an automatic. So I pushed my car from my driveway to the street 'cause needed to take out my other car from the garage. Before I moved it, seemed like the engine seized(problem I currently have). After I moved it, I tried to start it. It turned and made the same loud noise that it did before, then it got 'stuck'/seized again.
So after turning it both directions, then what? Should i expect it to get stuck? or keep turning? Make any kind of noise, etc?
thanks,
Carlos

Check your timing belt

Sorry, but it rather sounds like something is broken in the engine or in the bell housing. I suspect the first step in diagnosis will be to remove the transmission. If nothing obvious can be seen, pull the plugs and rotate the engine via the crank bolt and see what happens.

Have not had a chance to take a look since it's been very hot here in vegas. Thanks to all for a starting point.

UPDATE!!
Car started!!!

Jacked up the car. Pulled the plugs and I turned the crank by hand like you guys said. I believe I tried to turn it clock-wise and it wouldn't budge. I turned it counter-clockwise until fuel came out of the spark plug holes.
Tuned it clock-wise again and it turned! Kept turning and turning and didn't get stuck.
Put the plugs back in and started it. there was a noise as the car turned like a grinding noise but it started.
Might I add that when it seized on me, all power went out. Killed my battery. That's why I thought it was my starter. Took it to get it tested and it was perfect. There was a small dent on one of the teeth of the starter when I took it out. Now it starts but it makes this noise now:

Feel worried that I will be stranded if it decides to get "stuck" again...

Fuel came out of the spark plug holes? That makes me suspect a leaking injector, which could have dumped enough fuel into a cylinder to hydrolock a cylinder. Which could explain the loud noise and locked up engine.

Yes, fuel came out of spark plug holes. Sounds like I have to check the injectors. I replace filters and pintle caps on the injectors a couple of months ago.
Thanks Jlevie!

I'd pull the injectors and send them to RC Engineering for cleaning and flow testing. If there report doesn't show leaking injectors before cleaning & rebuilding, there is an electrical problem that is powering & opening the injectors when the car is parked.

That circular plug for the injector harness might be the culprit if electrical related.

[jlevie]

A problem with C191 could be the engine from running, or cause problems while the engine is running. But when the ignition is off there should be no power to the injectors. So there would have to be two problems; a) power to the injectors when the engine is off, and b) a ground one either or both banks. I favor leaking injectors.

Problem has not happened again after the car sat for 2 weeks. I reset the ecu before it sat 'cause when the problem happened. The car was sitting and I reconnected battery but did not let the ecu idle for a bit. I just drove it like I stole it, so this might of cause it.
