So I was driveing my 05 f350 down the road and out of nowhere it shut down. It wouldnt crank over or anything and the milage, trip, distance to empty, and fuel economy wouldnt pull up on the dash. When you hit the brake it throws a tbc code. So I tow it home and check all the fuses and relays and they are all good. I have a friend with a snap on computer plug into it and see what it says and it says it has no connection with the engine data sensor or trans sensor so he tells me maybe the pcm died. So I buy a new one and stick it in and it's doing the same thing. I did the thing I probably shouldnt have and disconnected the pcm entirely and it dosent change the symptoms I'm haveing. So I'm at wits end with this thing. Not sure where too turn too. I was told by the previous owner that it has one of those silly key fob imobalizers but that it's never worked so I've just left it in the door just in case. I changed the battery on the fob and it dosent do anything. I'm not against takeing the imobalizer out but I cant find the thing to remove it. Wondering what else to check before I start tearing into the wireing harness. I did a visual check on as much of the harness as I can and I dont see any spots where the look is damaged but I'm not sure if there is any common places where wires like to short out on these trucks. Any help is greatly appreciated because I have no idea what I'm looking for. I'm a 12v cummins guy trying to enjoy the luxury of a newer ford and I'm not enjoying it right now lol.
