It's telling you there is a problem in the circuit that operates the #2 injector. The first step would be to use a noid light to test the signals and if it doesn't flash, determine if it's power supply or trigger pulse that is messed up.

So........ You haven't proven anything except that the injector itself is not the problem. Switching the harness to a different cylinder didn't test anything. You still have a problem in the circuit that you haven't even looked for yet.

repeating the procedure-
put noid light on #2 injector -
1) on steady
2) flashes
2) no activity at all.
Which engine and cylinder is #2 where ? making sure we are all on same page

Looks like we're guessing on the engine size too.
