Won't start just clicking sound- all lights come on

Hello, it sounds at least initially like a dead battery, or a battery too weak to crank the engine. Have the battery charged and tested to see if it can withstand a load as needed. If not, replace it. If the battery tests good and you still have cranking issues, you could have a cabling issue or possibly even a starter motor issue. Testing is required. I'm pretty sure it's simply a battery, but you will not know until you check it out
