There is big chance that your load cell to be working.
I got the multimeter and with 2K Ohm I got the following measurements

So I realized that the "RED" wire was not the E+, but the white!
So I switched on the circuit the red wire to white and white to red
So
Black E-
White E+
Red A+
Green A-
So if you see a pair of same values your load is working! Not ALL manufacturers has the same colors.
I got the sensor from AliExpress (Chinese guy) and in the product description has wrong association
