Burned out PCM??

I was driving home yesterday and my truck suddenly shut off out of no where. Nothing on the cluster worked, but the truck would turn over just fine. So I pulled over to the side of the road and noticed one of the 30 amp big fuses was blown, so I had my buddy take me down to the parts store so I could buy a couple. I put another one in, and it blew. So I figured I had a short to ground somewhere. I was looking and on the driver side bank of the engine it looked like the wiring harness was resting on the valve cover. I pulled it away and the paint was rubbed off the valve cover, I put my last fuse back in, and my cluster came to life but for whatever reason the truck wouldn't start. I've read that sometimes a chip can keep it from running, so I went ahead and pulled my tony wildman chip out. I noticed that one of the prosessors or capacaters had a black line right down the middle of it. Could/would it be possible that my PCM burnt out from that wire on the main harness being grounded? Any help would be greatly appreciated, thanks in advance

try pulling the codes. see what they tell you. if that circuit did cross paths with the pcm, the fuse should keep it protected. could be the chip may not have been making good contact.

What year is your truck?

What fuse # was it?

What does your Owners Manual label that fuse as protecting?
