The ones under the manifold are primary. The ones on top are secondary. Only the primary injectors should fire when starting the car or runnings around town. The secondary injectors will only come on when under a load (WOT, accelerating up a steep hill, etc.).

The secondary fuel injectors (located on the Upper Intake Manifold) do not come on until 3,800 RPMs. So, the fact that the secondaries are not kicking on at start up, is not your issue. Because they're not supposed to.
