My Chevy Silverado 1500 reads the fuel level incorrectly. I already had the sensor replaced. I will fill it up and it still shows none and the low fuel light comes on. What can I do next? Thanks

Welcome to GMT Nation...
Our "GO-TO" Response for these Post-Repairs issues always seems to come down to having access to a Decent Bi-Directional Scan Tool that will allow you to "Scan and COMMAND" Modules to do certain things. Otherwise, with everything being hidden down inside the Fuel Tank, there is no other way to confirm that the replacement components respond and report properly.
The honest thing is to suggest looking at the identical problem via THIS Referral to another Silverado / Sierra Forum... and to mention that @TJBaker57 's suggestions for inexpensive OBDII Scan Tool Threads are worth investigating.
Obtaining an inexpensive VXDIAG-NANO Scan Tool that will emulate the Tech2 Scanner and allow access to the TIS2000 SPS Software for PCM Calibration Updates which might also be key to solving this problem. The "GYMKO" Tech 2 Clones and the VDIAG Tech 2 Emulators are also good all the way up to 2013 for most GM and GMC Vehicles... so your 2007 "Silvy" is well within that Update Wheel-House.
Visit these Folks...and see if they have come up with a better handle on how to solve this problem:

And for the the Folks with their 2007-2013 Silverados - Sierras planning to Drop their Fuel Tanks to perform the Bosch Fuel Pump and Sender R&R:
And an Alternative Method for the Fuel Pump R&R coming from Brian of "Briansmobile1" Channel.... But ...PLEASE... Choose either an ACDelco or a BOSCH Fuel Pump and avoid installing ANY other Off-Market Brand Fuel Pumps and Sending Units:
And Finally... A "D-Ray 3 Part Duplicate" of Brian's Technique:

My 03 did the same thing, it ended up being the ground wire was rotted off the frame, I put a bigger wire on, and it has been working good so far, 6 months now. BTW, welcome to the forum
