Ok ill start from beginning, my uncle passed and I got his 97 f250 4 wheel drive 460. Was bought in Washington drove to Cali then drove to texas. Truck was backed into my grandpas driveway and wasent cranked for 6 months. Tryed to crank it wouldn't start... No fuel. Switch for dual tanks was working cause it would change the fuel gauge to each tank. Put a jumper on the rear tank and it fired up. After that no crank... Lol. Fuel pump works no spark. Swapped all parts onto a crown Vic all worked. Read online on this forum that a guy said to unhook pcm if u get spark bad pcm.. Then he said to check for hot and grounds on the harness to make sure it's not bad wiring so it's all good but figured I had bad pcm. Pulled pcm out and the whole outside bottom was rust. Pulled part number called orille's they don't have a replacement with the last 3 at AMD so what pcm do I have? The number is f6tf-12a650-amd. They have like aha at the end. This one don't.
