    Truck wont crank

    I cant get my truck to crank over. Changed Batteries, cleaned cables, I'm almost positive the starter is clicking. I'm going to pull the starter off and see if its bad first. Any other ideas??

    There is a starter relay in the electical box under the hood. Swap it for another similar to it and see if that fixes it.

    Not likely, unless the contacts are fried. Just swap them around.

    I bought a new relay and switched it with all three and nothing happened.....
    Next step is to pull the starter I guess

    Have the battery checked while you have it down, you could have a dead cell.
