You're possibly pinching the o-rings on the injectors. Make sure they're lubricated, I just lick my fingers and wipe the o-ring with them, and that you're spinning them in, not just pressing them in.

Why it won't start though, that's weird. Is it turning over at all? Need more info on that

Don't forget to check the ground by the diagnostic plug if you messed with it. Leaving that loose has caused many a no-start.

Other than that, tough to do over the internet with what you told us. Spark, fuel, compression, timing.

oops. I diagnosed a bad injector on a third gen not too long ago as well. opted to replace all six because if one fails, the rest are not far behind.

Did you reuse the OEM metal gaskets for the upper and lower half of the upper plenum? remember to plug everything in again? I'm sure you were less than pleased to have to pull it apart again...and that's where mistakes happen. Just comb over everything.... MAF connector, injector connectors, coil connectors, ground wire... TPS, IAC etc.

It also appears that your caps lock button is stuck.
