cranks but won't start?

I'm a few days behind you, Slicknapier! I just put a Mighty-Vac on my fuel line to draw gas through the pump and filters, didn't want to start the pump totally dry. I put a pressure gauge in the fuel line before it connects with the original line on the fuel rail. Mine is a 2001 Ram 5.2.

Ours doesn't have the regulator on the fuel rail. At some point, don't remember which year, the federal gov't mandated the pressure return be inside the fuel tank. I think your year also runs at a somewhat lower fuel pressure. I had a fuel rail from a 92 Dakota, but it wouldn't work without switching out the fuel injectors so I used the 2001 setup.
