Unfortunately, I have to become a member as well. I'm having the same problem as "vortechf150" that he posted on 5/7/06. I bought a 2004 F350 with 36,000 miles. Everything was fine for a while, and one day it wouldn't start. It cranked but wouldn't start. The next time I tried it, it started right up. A few months later, it did it again, but this time it wouldn't start a day later. I changed the cam sensor, and it started. It has done this 3 or 4 more times since. The last time, it wouldn't start for 2 days. I took it to the dealer, and they have no clue what's wrong. There are no error messages, so they have no idea where to start. Has anyone else had this problem or have a clue what to do...?
