I didn't think it was possible to install the shutoff pod in a way which would act as you describe, but I'm really not sure. The usual problem is a runaway where the pod jams the rack towards the full-fuel position, but you obviously don't have that going on.

Actually, I mean that the IP itself could have the shaft stuck in the "lean" position, but you bring up a good point that the ALDA could possible be frozen as well (however, it's far less likely to be the ALDA). With the ALDA removed the pump should be in the "full rich" position, as long as the shaft moves up vertically. You should be able to press the shaft down with your finger (it takes a fair amount of pressure) and watch it spring back up when you take you finger off. It only moves a few mm though from top (full rich) to bottom (full lean).
