5.9 Magnum help needed

Alright so I tried the code trick but I didnt get anything. It didnt blink at all. I also listened for the fuel pump to prime again and sure enough... it did. Even though the fuel pump primed it wouldnt start. Theres a fuel pressure valve on the drivers side fuel rail and I also checked there to see if I was getting fuel to tyhe engine... well, I am. So Ive eliminated 2 points in the triangle. I have spark and I have fuel. I only have 74k miles on the truck so I should still have good compression in each of the cylinders. The only thing that I can think of would be the timing chain. Could it break or fall off? The truck died as I was driving at 25 mph. Couldnt the timing chain have popped off or broke during that time? It would just fall to the bottom of the cover? Im pretty beat down this week. I have my barracuda, ram, and ninja yet ALL of them are out of comission now. With 23 units im burnt. Any suggestions?
