Ok guys here's one for ya. Turn the key and nothing. Turn the headlights on and I get a clicking sound in the taillight relay under the hood. Relay has been replaced and the battery has a full charge. Any ideas? Was told I might have a bad ground? But where?

What about the starter? If it's locked you can always hit it with a hammer to try to break it loose. I don't remember if you can get a hammer up there or not.

check the resistance between the negative terminal of the battery and the frame. it should be low if its not try a different spot on the frame if you dont get a connection anywhere check your negative battery cable

definately check your wires. Make sure there are no ends where they are touching metal. Also check that ground.
