P0171 and P0174 are considered lean code in bank 1 and bank 2.
Looks like you have a problem with number three cylinder. The injector appears clogged or faulty. The misfire in cylinder three with fuel cutoff is probably all related. You will have to correct each problem individually. Perhaps correcting one problem will also correct some other problem. I would start with cylinder number 3. Check coil pack, spark plug and fuel injector.
The low fuel pressure code could be a clogged fuel filter. When was the last time you had the fuel filter replaced? Fuel filters are close to $100.00+ labor. Most owners don't replace these until they have a problem.
