Fuel Pressure @2000 PSI After Engine SWAP?? (Chevy "Craptiva" GDI P0089) 

Here we go again...another modern GM GDI engine that is NOT having a good day.
Supposedly the car drove "fine" for a few days after an engine replacement, but now it's definitely NOT HAPPY!
Only codes set are "P0089-Fuel Rail Pressure too HIGH"...interesting.
Lots of variables with an engine swap...This one might need a few more parts!
