Got more info for you guys.

The problem started out of no where according to the owner, coming home from work and the car randomly died. The next day he went to go get it and found out the main ignition 1 fuse had blown, replaced it, made it about a block down the road and it blew again. Then he was a dumbass and used a welding rod to bypass the fuse, that got him a good 30 miles till it melted through.

I've got the whole dash taken out and ive found a few crispy wires from some problems he had with his cigarette lighter a year ago, but i cant find anything exposed. I've gone from the ignition on the column to the firewall, from the under hood fuse box to the firewall, and from the ECM to the fuse box and firewall.

Dont see any shorts, whats the first part i should try replacing?
