Hyundai Elantra GT won't start, only clicks despite new battery and capacitor replacement on Hyundai Elantra GT

Some Hyundai Elantra GT owners report experiencing starting issues characterized by a clicking sound, even after replacing the battery and capacitor. These problems may stem from a weak battery that fails to hold a charge properly, despite being new. Additionally, loose or corroded battery cables can disrupt the connection, contributing to the starting difficulties. A faulty ignition switch is another potential cause that may prevent the vehicle from starting. Some owners find that the clicking noise indicates insufficient power to engage the starter motor, which might require inspection or replacement. Furthermore, issues within the fuel system, such as a clogged fuel filter or a malfunctioning fuel pump, can also impede the starting process. It is recommended for owners facing these issues to test the battery, check battery cables, inspect the ignition switch, verify the starter motor's condition, and evaluate the fuel system components for any faults.
