02 ls camaro wont crank... Okay so hears the story i just got done building my 5.3 block to go back into my 02 camaro. I've rotated this block to make sure everything was good and it rotated perfectly no problems at all now that it is in the car i can even get the block to rotate over with the breaker bar and it barely rotates with the engine trying to start. Initially it did start once then kinda died and i didn't think much of it i did prime the system before the initial start. The battery definitely has enough voltage so that's not the problem i pulled the spark plugs out today and i still cant rotate by hand I'm just kinda confused on where to go next. Im sure someone else has experienced this before and i would appreciate any and all help thanks guys.

If you are sure its a mechanical issue and not a electrical issue pull your timing cover to confirm the marks are still lining up on the cam and crank sprockets. There is a chance it jumped time if the pin holding the tensioner was accidently left in. Then loosen each one of the rockers that is compressed to close the valve and try rotating by hand. If the engine rotates with the closed valves then you should pull the heads and check for damages since you started the engine.

Wow a lot if drastic diagnostic measures posted above, since you mentioned it turned over fine prior to installation, here are a few things I would check first, is it a standard? Are you sure you put the clutch disc in properly? Is it an automatic? Are you sure the torque converter is properly seated? Did you have any issues when you mated the engine to the transmission?
Are all your belt driven accessories in good shape? Have you spun the tensioner pulley, idler pulley, power steering pump pulley, alternator pulley, water pump pulley? All of what I mentioned has the possibilities of not letting a motor turn over, and are much easier to check than opening up the engine to check internals.
