When switching from pool to spa the pressure in the filter is so great it will force water past a brand new O ring seal what would cause such high water pressure?

Try turning the pump off before switching to SPA and then turning the pump back on. Many pumps when turned on/off create enough pressure to break the seal on orings and cause a short burst of water from the seal. This can also damage the rings on sand filters when the pump is not turned off prior to switching from filter to backwash/recirculate/waste. Summary: always turn the pump off before changing the direction of waterflow.
And there could also be another valve to open or close to accomplish the task.

Yes, replace filters as needed. Brand new in-line filter still can cause flow restriction.

A plugged up fuel filter, a faulty fuel pressure regulator or a faulty fuel pump.
Would the fuel pressure regulator cause the injectors not to get gas?
It could but not likely. Do a fuel pressure test and be sure to replace the fuel filter. If you have low or no fuel pressure I would suspect the fuel pump is at fault.

Try a new fuel filter. Back pressure of a plugging filter can cause it, it doesn't take much sometimes. I had a silverado doing that . Ed
