18 stampede cranks but no start

[Jon W]

Hey all. I recently got a stampede given to me and was told the engine was seized up. Long story short I got a new battery in her and bam she kicks over. New plugs, sound a comparable cam sensor since that's usually the issues. Had abput 40 codes on her but clearing them and installing the new battery the only one coming back.is the cam code. I can crank her and she'll hit but will die. I've had her running for about 10 seconds sofar and haven't heard any knocking or anything.  Does anyone know where else to start mostly she'll crank and stumble like she's trying to hit but won't. Does anyone have another cam sensor number that I can get locally?

Sofar I've done.

New cam sensor, and old one does the same.

New plugs, old ones had good spark but jus wanted to be safe. 

New fuel, fuel pressure is amazing,

New battery, cleaned and tightened all connections.

 

Thanks
