Help!!! sparking from the battery

first thing, make sure that the battery connections are clean... grab some sand paper if you dont have a terminal cleaner, and clean inside the connector, and the battery posts.

So I have tried several things. I have replaced the battery, the starter, I checked the main fuse, and I checked all the wiring and found nothing. I also tried using a wrench to move engine just to make sure it rotated freely and does. I still cant get the damn thing to turn over. My voltage is good and my grounds are good. But now I dont have a spark coming from the battery when I try to turn it over which is a good thing now, but I dont hear a click from the starter almost as if it is not hooked up at all so I dont know what it could be. Oh and I cleaned off the terminals.

check your grounds dude, they may look fine but not be, use your multi meter and do a continuity test

the main wiring on these trucks a simple, find and follow dont over think it

good luck
