I didn't. Just the line to the rail. I'm thinking injectors because there was some crud in the original line. Small amount..... But yes. Eye brow was raised

Tomorrow at some point ill pull the injectors, clean them with some spray stuff and see if they are clogged. I'm at a loss with this so might as well. I'll check back in after injectors. Really weird because I can smell gas in the exhaust.
And it starts with ether!!! Shuts off immediately but it'll start!
So its like it has to be an electrical issue, but I don't know!!!!!
Losing my mind! Haha

I just ordered new ignition coil and new wires to eliminate that even thou it has spark- seems to be weak spark so just ordered because. Will be in Thursday.

once the piump is running it would have pressure when you disconnect,from the tank, but you should check to see if there is pressure from the rail side, If you do yes check the injectors, but it should still try and run with a dirty injector. Dont waste money on a coil and wire yet, pull one plug wire off, and attach to an outside plug grounded on the engine and see if it contiues to spark while you crank,
Also check your compression

I have a compression gauge, but it was running... I don't have a fuel pressure fitting at this moment.

Since the motor does start and run, it seems like flow is restricted and not plugged, I'd try the line first..

Come to think of it, when I rebuilt the internals of my '07, I had it all buttoned up and the tank installed on the bike before I tried to plug in the fuel line to the check valve... and it didn't fit.
The replacement check valve did not fit the OEM hose/fitting that goes to the injectors.

If I were in your shoes, I would swap out that new check valve, especially since it ran prior.
