Gas cap hissing. Can’t barely pump gas.

Also my long term fuel trims are reading -10 and -12 in both banks. Am I running lean? Could the clogged lines or bad purge valve vent solenoid cause this

Running rich. The PCM is taking away fuel (negative trims) because it's being told there's too much fuel by the O2 sensors. A bad purge valve can cause this, among other things, as can fuel contamination in the oil.

Just opened my hood and my coolant is very low for some reason as well …
