Super exciting that the car is back to normal. I finally got my car back together yesterday and couldn’t make it out of the neighborhood without our good friend mastervac plausibility limp mode. Plot twist: my pump is running, wiring is all good. Ordered another pump and hose/sensor. Don’t have any time to diagnose it so I’m just throwing the kitchen sink in and hoping it resolves it.
Not sure if the plumbing is exactly the same. But I am trying to get a copy of the VF install instructions to see if they can shed any light on it.

Sorry to hear limp mode/mastervac is continuing..... Weird that we both got hit by this at the same time. Hope all the new parts solve it.
