There is a fuse behind the NIT (the unit under the arm rest).
Additionally, does your mechanic have a scan tool that accesses the F1 system in these cars? I think I mentioned this before, F1 pumps don't just continue to fail. There should be hard codes stored in the NCR (TCU) of the car that will point to what the issue is. This is why people are so scared of these cars, and F1 systems. People don't know what they are doing when they are fixing them. They are guessing at what the issue is, instead of not only doing proper diagnostics, checking the rest of the health of the system after they replace something.
Here's what we need to know:
1) When the gearbox (NCR) was scanned what codes were present? (Not talking about Enhanced Powertrain from a Snap-on scanner, you need a scan tool that can unlock and read the NCR of this car).
2) What's the solenoid on/off leakage rates?
3) What is the clutch wear readout?
4) What is the clutch degradation index (also known as clutch wear index)?
5) When the car did run......sitting idling in neutral.....how long before pump cycles? Ie.....pump comes on.....cycles....shuts off.........30 seconds later.....pump comes on again. It's the timed interval I am looking for.
I'm not trying to be overly harsh towards you or the mechanic. I am trying to get you on the right stretch of highway in order to get you going where you need to be at. My thoughts are your mechanic doesn't work on these cars, or doesn't have the scan tool necessary to access them. If he did you wouldn't of picked up the car again for it to fail.
Without the information requested above we would all just be guessing about what the issue is. That could stem from a failed or glitchy clutch position sensor, actuator potentiometers, the actual NCR itself, .....etc. This car is not the car you want to replace parts on to find the issue. It will become really expensive, very fast.
