2006 powerstroke diesel has been running fine. Shut off it off for about an hour then it would not start. The engine turns over and all indications are normal. The first couple of times I tried to start the engine it acted as a gas engine would that was not getting enough fuel. Then nothing but the engine turning over. The fuel filters were changed about 5000 miles ago.

This basic diesel engine troubleshooting link may help:
