How to replace starter

??????

Lol if it wont even turn over why wld u replace all that?

Is your security light on? If so it's a security system problem. Hope that helps! Jim

Do you know the condition of your battery? Will the car crank? Will the car crank with a jump from another car? Are all battery/alternator/starter cables corrosion free and tight? If your battery is good and all connections are good then the starter might be the problem but you need to verify before just changing parts. Plug wires and plugs will do nothing to resolve your issue and just changing things without a reasonable diagnosis will just cost you money.
