Narrative:

On aircraft X, the left inboard igniter plug was not installed and this is my part in the chain of events that happened. I accomplished an operations check of the right engine ignition system as per the discrepancy on the post run up card. I distinctly heard 2 snaps which confirmed both left and right system were operating. Supplemental information from acn 582305: received job card to close engine areas after a boroscope inspection. Paperwork stated on #1 engine that the outboard igniter was removed only. In reality both outboard and inboard plugs were removed. Igniter at this time the inboard thrust reverser cowling is down and shut the entire time. Only the outboard igniter plug was reinstalled working off the knowledge of the cowling being closed and the statement of the outboard igniter plug was removed only. The aircraft would not start in ZZZ and it was discovered the inboard igniter plug was not installed.
