When you guys did the rebuild, did you install new reference sensors or reuse the old? I'm just wondering if they are old enough to have some issue with the wiring itself. Try messing with the two black connector wires where they lead out to the actual sensors on the back of the engine?

How old is the fuel pump? They can be pesky with age as well.
We did replace both flywheel sensors with new Porsche parts.

As far as I know, fuel pump is original.

I've got some troubleshooting to do. I've just been having so much damn fun driving the car.

Thanks for the ideas!
