Ok so she cranks all day but wont start, no codes at all. I changed the fuel pump,crank and cam sensors. i cant think of anything else that will keep it from starting. Its an automatic

 

sounds like it maybe your batter, battery cables, or your alternator

 

since it "cranks all day", it soesn't sound like the battery, battery cables or alternator to me!
check to see if fuel is getting pumped to injectors and if you're getting spark; i'm assuming you already checked fuses, right?

 

camshaft/crankshaft position sensor good? u pulled some codes?
Edit: nevermind I just read the top DUH

 

Have you tried giving it a shot of starting fluid?

 

Fuel filter or a ground on the intake manifold happened to me ,similar symptoms, good luck
