Check Engine After I Cleaned Intake Valves and Replaced Fuel Injectors

So I took the afternoon to clean my intake valves with some LiquiMoly Valve Cleaner and a nylon brush. While I was there, I decided to change out the fuel injectors. Once I started it up, a check engine light popped up and it's reporting low fuel pressure as well as misfires in cylinder 1 and 3. Additionally, I can't roll my passenger window, AC controls aren't lit up anymore and the engine bay also has a noticable fuel smell.

I'm thinking it has to do with my failing to properly torque the fuel delivery valve along the fuel rail. I thought I got it closed enough but I'm thinking it's clear I didn't. My main question is **if I can manage to pull the injectors out just enough to properly seal the pressure valve, will I have to reseal them?** I just want to pull them out not even an inch to get that valve properly seated. I suppose I could also just take the fuel rail off and keep the injectors inside just in case; I just need to know when to reseal.

Any other ideas would be appreciated too.
