A (different?) won't start SR?

[st280]

So my redtop SR's waterpump started going bad (leaking through weephole). And my injectors seemed like they weren't sealing right/they were plugged up.

My car has started and driven fine for about a year now. I replaced the water pump and injectors (with new o-rings) last night, and decided to let the sealant for the water pump sit over night. Button everything up and call it a night.

Try to start car this morning, and turned over for a couple of seconds then just stopped turning over. Check to make sure everything is how it should be installed. Try to start again, and engine won't even turn now, and starter is still making a noise and everything like it's trying to spin.

I tried to manually turn over the engine with a wrench on the crank and it seems like I'm hitting a wall or something where I can't even turn it over (not a small guy).

I also noticed that it seems like there is fuel coming through 2 of the injector caps (I thought is fine until car actually runs to seat the o-rings?)

What could cause the engine from not letting me turn it over at all?
