You will need to move the rack back and forth to get the pin to line up with the slot.

Thanks for reply...
But I think the rack. Or the pin is Froze up.. It wont move at all.the injector pump will come up but just to the top of the stud bolt at the top of the pump.The little pin that moves back and forth on the pump is froze up in kill position. Or stop position. Now what.

still need help to get Injector pump out..while it is froze up..
