What is the sound when idling that sounds like crickets

Tinkling noise coming from 3lt diesel engine 2007 no modifications

I have a problem as my prado 2009 model cannot start as the alarm keeps on sounding and the remote on the key is not working. What should I do?

engine starting and immediately stalling. codes showing communication problem with immobiliser so i swapped ecu with ecu that doesn't have immobiliser , engine runs but goes into limp mode because ecu can't see knock sensors is this a wiring issue or is the ecu defective

Why does my car makes noise from the engine and cut speed normally makes it at 100km/hr so it reduces the bad sound whenever I leave the accelerator pedal
