    Using sed:

     sed 's/^\([^|]*\)|0*\([^|]*\)/\1|\2/' input

    Which matches, captures and preserves the first column in \1 via ^\([^|]*\) and captures the second column in \2, skipping the leading 0’s via 0*\([^|]*\). Then it replaces the matched part (columns 1 and 2) with the captured parts of these columns via /\1|\2/.
