I just joined to get some help on a crank no start when hot problem on my 05. I have dissassembled the fuse box and found no problems. I reinstalled and found that when it will not crank relay 42 is not getting a ground signal. That pin in the fuse box is not supplied by the copper trace wires in the box. I am now wondering if it may be the ECU since it is located in the engine bay. Any ideas???
