Check the fuel rail for fuel,may be bad fuel pump or relay,

i checked fuel pressure on the fuel rail and i got 40psi when eng was cranking
Have you checked the crank sensor?You said you already replaced cam sensor.

Digging too deep today is January 30th and after throwing almost $1,000 at my Dodge for the same issues I found out it was in the cylinder not receiving power it needs for the injectors to fire so I ran the constant power wire directly to the auto shutdown relay in the fuse box, and the negative that is a pulsating ground, run it directly to the ECM clear all your codes there's your fix goodnight ladies and gentlemen
