check engine light fuel sending unit rusted out replace

I paid over $1650 to fix it and the engine light is still on and the code says fuel system, NOT PLEASE

VEHICLE IN GREAT SHAPE, MOTOR OIL CHANGED EVERY 3000 MILES. AFM ENGINES HAVE A HISTORY OF BEATING UP LIFTERS AND CAM SHAFTS, CAUSING ENGINE TO MISFIRE. WHY HAS THERE NOT BEEN A RECALL ON THIS ENGINE WITH THE HISTORY OF THIS ENGINESFAULTS? ARE THERE ANY ACTIVE CLASS ACTION LAW SUITS?

Check engine light constantly comes on. Dealer couldn't pinpoint problem while under warranty they always came up with different problem (gas cap bad, engine oil low, etc). Now out of warranty and light still on. Can not use my remote start when check engine light is on. Way to go Chevy. I've had so many issues with oil consumption, power door locks & windows and remote start. Why hasn't there been any recalls. Seems as though everybody is having the same issues.
