My 1.9 Jetta won’t start clicks once

Hello, can you be sure that the engine turns manually - with a breaker bar and socket on the crankshaft pulley? This is to ensure the engine has not failed internally and seized for some reason. Other than that, battery voltage, cable secure connections are the only places to look, check and double check. The "click" indicates the signal is happening, but too much resistance to start. https://repairpal.com/auto-repair-near-me
