7.3 powerstroke issue

[TwinTurboNotch]

Does anyone have any knowledge on the 7.3 powerstrokes? Mine quit running. It had been running fine with no issues, I left the house the other night and it made it about 500 ft and the check angine light came on. I decided to drive it around the block and bring her home but she didn't make it. It just quit and wouldn't start. I tried changing the cam position sensor but that didn't work. I plugged in a code reader but it's not showing any codes. It will fire on ether so I feel it's a fuel issue. Unfortunaly I really don't know how to trouble shoot this fuel system. Any suggestions are welcome.
