How are you certain the engine isnt getting gas?You need to isolate your problem
Are the pumps you changed new?you sure the pumps you changed working?
1.First off you should scan the car for any OBD errors
2.Have your mechanic connect a fuel gauge and check pressure coming before and after the fuel pump in the engine (GDI technology requires high pressure to injectors) to isolate your problem
3.The cs has a filter in the tank,this and the pumps can both be cleaned

Cylinder not firing could be due to bad/damaged spark plug or coil pack.

Post your problem to the CS forum , you may have better luck there.
Also get a mechanic that has experience with these cars, else you just gonna be spinning top in mud
