That looks like an aftermarket hose to me, and with it running by the fuel lines I would venture to guess that the hard plastic line was cracked or otherwise broken at some point and someone replaced it with that... So if you have hose's plugged into the evap solenoid I would think you have a hose plugged in the evap that doesn't belong and goes somewhere else<<Just a guess) Sounds like you got spark and fuel from what you've checked and the rockers are pretty straight forward so I doubt you messed those up... Check the plug wire's? I mean to make sure they aren't crossed is all.
