Default 03 chevy suburban 1500 z71 keeps blowing pcm fuse.

So bought my 03 chevy suburban a few months ago. Love the truck. A week or so ago it wouldnt start. Had blown the pcm and the ecm fuse. Replaced the fuel pump last saturday. Thought that might have fixed the issue. Nope yesterday blew the fuse again. Cant see to pin down the issue anyone ever had this problem?

Its shorting out somewhere. Might even be a bad ECM.
