Narrative:
Installed svcable APU on aircraft. APU would not start; could not perform functional check or leak check. Both checks were still applicable; so I did not feel it was right to north/a the blocks on the work card. After further discussion with my crew chief; we decided to north/a the steps on the work card to close the work card out. The FAA inspector also recommended we north/a the open steps. We have been told that every block on every card we work must be signed or north/a'ed. What if an applicable task cannot be performed leaving a partial work card?
