Intermittent injector pulse

[thequif]

I’m working on a 2011 5.7 2500
With P0302 misfire cyl 2
#2 injector pulse is intermittent
I’m thinking it’s the harness back to pcm or a connector pin at the pcm
I want to start at the pcm connector anyone have pcm connector diagram for this unit

Thanks

Truck wont run? At all or starts then dies?

I don't have diagram.

Truck always runs, sometimes runs perfect and then other times rough. When it runs rough the engine light flashes and has code P0302 when I test cyl. 2 injector signal the test light is intermittent. Sometimes it’ll run for a day with no issues
