'09 died, cranks, no start

Hello all. Looking for suggestions as to why the wife's '09 6.7 won't start.



Changed head gasket, started 'er up. She idled for 20 or so minutes and we jumped in for a test ride. Went about a 1/2 mile and it just plain died. No stumble or miss, just flat died.



Pulled it back to the house and did some internet research.



Found a thread on cummins forum where a fella was getting fuel to the cp3. He unhooked the wiring to the cp3 with no change. He them took the feed line to the rail off and had someone crank the engine while he watched for fuel. He stated that no fuel was present at the removed line.



He deduced that his cp3 was bad. His truck started and ran fine after replacing the cp3.



I did all the same stuff to the wife's truck and no fuel is coming out the supply line to the rail.



We had a barometric pressure and high intake air temp codes. I tried clearing them with the smarty with no luck.



Should I be ordering a new cp3 or could something else possibly be wrong.



Truck has been deleted with smarty s67 and has 60k miles on it.



Any help is greatly appreciated.
