Fuel Rail Priming?

Fuel Rail Priming?
Today I removed the intake manifold and fuel rail, resealed it all and put it all back in. Went to start the truck and it cranked, caught an revved real high. Then it stalled.
Tired a few times and got the same result. Attempted to prime the fuel rail with by cycling the key 20 times and got a bit farther. It ran longer before stalling. RPM's dropped then it picked up and died.
So I'm looking for how to prime it (maybe) and then get it started.
Thanks.

Pretty sure it is. I pulled and cleaned it today while it was all out then made sure to plug it back in. I’ll double check in the morning.
The 8 new upper manifold gaskets look different from the originals which had little cubes on either side and the new ones don’t. BA said the new ones are updated but it looks like there are open areas without the cubes.
Anything else to check out?

What prompted you to do the intake in the first place? Is it possible you're chasing the original problem and the intake was not the fix?
For a vacuum leak a smoke tester can be great. You can also redneck it and use shots of starter fluid around the engine to see if you get an idle/starting behavior change, but it can be a little dangerous if you overdo it.

Dumb question, but you're sure all 8 injector electrical plugs audibly clicked when you plugged them back in?
Probably worth smoke testing around the intake manifold to rule out an issue with the new gaskets.
If you have a GAP tool, there's a procedure on it for purging air out of the fuel system

I will double check the injector plugs also. For that matter, all of the plugs.
Re: GAP Tool. Is it the fuel prime once under service > engine? Or is it something else?
I tried the fuel prime but didn’t notice anything happening although it said it completed ok. Also reset adaptations too.
