Brand new fuel pump which is running, fuel pressure at the schraeder valve, and I have spark. I did get it to start yesterday but it was very stubborn about it and ran rough.

EGR?
throttle body?

have you cleaned them?

fuel filter - have you changed it lately?

How much fuel pressure?

If you haven't tested it, I suggest you do.

Just having fuel flow is not enough.
