I have a 2006 f250 superduty 6.0. The truck ran fine a week ago and than died as I was going to take it for a drive. I figured out that the fuel pump (air dog system) was not working. I fixed that and primed the pump. The truck still won't start. When it first happened the truck would crank but not start. Now all I hear is the starter but no cranking. Both filters could be replaced. The bowl to the upper is dry when I take the cap off. However fills up when you turn the key on. I'm not sure what else to try and I need to get this truck started. Any help anyone could give would be great! Thank you in advance.

 

To clarify, you hear the starter but the engine does not crank.
That means you have an issue with the starter teeth not engaging the flex plate, or perhaps your batteries are run so far down the starter is just clicking?

 

Crawl under there and tap the solenoid and see what happens... that may get it to spin.

 

I'll have try that's thank you
