Check your fuel filter again. Dirt from the tank could have clogged it again.

I have a vortec v6 and it starts when it wants to. i changed the spark plugs, wires, coil, distributor, cap, and roter, checked the firing order, set it at one, nothing

You may need a intake manifold gasket.If it puts prestone in the cylinders then it will be a ***** to start.You also need to check check the fuel filter.
