OBD2 codes here:- https://www.obdadvisor.com/most-popular-obd2-codes/

 

If you scroll down just below half way there is

P0300 Random/Multiple Cylinder Misfire Detected

followed by Symptoms, and Causes.

 

No mention of the P and H you quote, or of pressurised fuel tank.

 

I don't understand why a fuel tank would be pressurised - or how. Could it be a partial vacuum? - I expect you hear air moving, but could it be going in? Howzabout the vent in the fuel cap / tank being blocked and fuel use creating a vacuum?

 

Any info on a Fiesta owners site?
