Can anyone pls troubleshoot this circuit?
Apart from a missing connection dot between the amplifier output and R1, it seems reasonable. 

The 10k feedback values are plenty low enough to drive the input bias current, and plenty high enough to be driven by the amplifier.

The input voltage common mode range includes ground on the LM324, and the output will get near to ground, even if it won't sink much current when the output voltage is 10s of mV. If the load is connected to ground, then it should pull the output all the way down to ground for zero input.

With a gain of 2, you will saturate the amplifier output before you reach the upper limit of the input voltage range.

12v is a reasonable power supply voltage. The amplifier has specifications at 5v , and a max supply IIRC of 32v. I usually get the quad amplifier power and ground the wrong way round, they are on the wrong sides for me. You have drawn the schematic correctly, have you wired it up correctly?
