I'm thinkin that your dropping about 1/2 volt or so between the battery and the fuse connection through the ign switch and wiring for the vac pump. Possibly a slightly resistive connection but I would make sure that your battery is fully charged since you were doing fuel pump testing and they draw at least 4 amps each I think. Also, since that vac pump ckt is separate from the DIS module I don't see why the pump shouldn't run. In theory if you put 12V on the dk blue lead to the vac pump with the fuse connector off she should run.

Good job finding those 2 parts. There are so many nooks and crannies on these motors that people have lost small animals and ratchets and.... and...
