The Fuel Gauge May Not Read Correctly and/or Check Engine Light With Code P0455/P0461 on Pontiac G6

Problem Description and Possible Solution

The fuel gauge may not read correctly and/or the Check Engine Light may illuminate with code P0455/P0461 stored for a fuel level sensor issue. These faults may be caused by a fuel vapor line inside the fuel take interfering with the fuel level sensor. If this is found to be the case, repositioned and securing the vapor line should correct this concern. If no fault is found with the fuel vapor line, the fuel level sensor itself may be at fault.

I have the G6 3.6 GTP. My check engine light comes on at miscellaneous times. I have to clear the 2 codes yet still runs fine. Now, when I get fuel , the car will crank but not start until I hold the gas pedal to the floor and try again. This problem has yet to be fixed.
Low fuel came on and the fuel gage read empty whdn I filled the tank and a right after that check engine light came on.
I had a fuel leak, and had it fixed turned out it was the fuel pump, so I pick up my car and the check engine light turns on and my gas gauge isnt moving it just sits on E. Not realizing what the symbol was at the time, I drive off. I put gas in my car and the gas gauge didnt even move!Im taking it back today where I got fixed at.
Codes po455,po461,po463 come up...this happened after I replaced gas cap with new one after I lost original.
