I am trying to figure out why I have no crank no start on my 350 super duty 6.0. It was running fine when I parked it but when my husband went to start it a couple of days later it would not crank or start. We pulled the starter relay and touched the + side of the battery and it would crank like that but no start. Someone told us it was the neutral safety switch but we caint find it. We have looked under the dash on the steering column and on the side of the tranny. Can anyone please help me out here?

 

It's happened to mine driving, complete shut down, pulled over got towed. They found the FICM had fried. A few days after the repairs I found radiator reserved was leaking and covered the new with coolant not if that was the first problem or not. I replaced it and added aluminum tape to the bottom hoping to give it some protection from the heat coming from the exhaust and turbo.

 

This thread would get more exposure in the 6.0 forum. Lots of knowledgeable and talented folks hang out there.
