Maybe test continuity on injectors 2 and 5 using an ohmmeter, see if there is infinite resistance (open) or not.

Its amazing what big problems a little corrosion on fuel injector connectors will cause. I had the same thing happen with my Jeep...cleaned the connections and the problem went away. Dielectric grease ftw
