Anyone know what is the problem if a car won't crank up? My Civic '96 EFi (Manual) can't start at times. When I insert the key and crank it up, it will not crank. It just go.. "karak".. and nothing happened. I can still on my aircond and lock my car (central locking) which means battery still working right?

Anyone had the same problem? OR anyone know what can be the problem?
