It could be something in the tank, yes, but the only way to find out is to drop the tank out and inspect it. There might be other issues as well such as a bad sending unit, clogged fuel filter, etc.

Sometimes it will set a trouble code, other times not. You would have to remove it and look for corrosion, or deterioration.

It should be above 45psi with the key on and hold steady while running. If the pressure drops off or is lower than spec, you either have a bad fuel pump, or a restriction in the fuel delivery system, or a bad fuel pressure regulator.

Have no idea, it could be a multitude of things. I doubt it is spark plugs. You should still check the fuel filter, it could be clogged. As we as check the fuel pressure regulator for leaks. It could be a clogged catalytic converter, low compression, or other internal issues, or even another faulty sensor. This really needs to be checked out in person by a live technician. Take your car to a shop would be your best bet.
