Every once in a blue moon, Especially when the truck is still warm from being reciently ran, it will just turn over like its not getting fuel. I'll stop cranking it after 3-5 seconds, wait till everythings stopped moving, crank it again and it fires right up. Whats up with that?

 

Thanks for the quick response...

 

CHECK/RE-TORQUE YOUR CROSSOVER TUBES AND SUPPLY LINES.
Read my post "03 Cummins idles high wont start hot" my problems began with symptoms like yours and gradually got worse over the past few months. The tubes were loose.

 

Thanks dude! I was hoping for something simple. Glad I dont have to buy a FASS....yet.
