There was no recall for the injector connectors-- or wire harness. GM did have a "fix" for the injector connetors-- which you cut the connector off and install a new one, along with new brackets. (about $250) This fix did not always work.
One that seems to be better--- is to use a SHARP ice pick and push it into the connector, which raises a dimple in the terminal for better contact.
The P0202 code is for #2, the driver's side front connector-- I suggest you try that, after you inspect the FICM wire harness. The other connector that you may have problems with is the rear on the passenger side-- that is #7.
