All I get when I turn the key is the relay clicking. I replaced the starter with a new one. I tried the battery out of my truck. The battery posts are clean and tight. The connections at the starter are clean and tight. The ground at the block is inaccessable to wrench or hand but I pried on it with a screwdriver and it's tight too. Both the ground and hot wires to the starter appear undisturbed and undamaged. The only other thing I can figure to do is run a new ground wire to somewhere on the block that is more accessable but I hate to mess up the factory wiring if that isn't it. Where do I go from here?
