I checked the temp sensor in the compressor and it's open circuit and that's why the compressor won't run. I don't know where that sensor is inside the compressor motor housing.
I swapped compressors with another that I'd rebuilt at the same time and it won't pump up the tank either.
Re the air leak I can hear, I'm pretty sure it's coming from the over-pressure blow-off (relief) valve. When the pressure drops, the hissing stops. I might swap it with one from the other valve block I'm about to rebuild.
I came across a document by Lee Bourgeois about the EAS and he suggested a test I've never done - spraying detergent solution around the solenoids. Sure enough, the inlet and outlet valve solenoids are leaking slightly even though I replaced the O-rings under the solenoids. It makes me wonder if the solenoids underneath are also leaking. We need a test bench to put air into the system to check for leaks before fitting a valve block back into the car.
Now I've got leaks from my manual inflation system fittings so I need to replace their O-rings. Unfortunately, the O-rings in the EAS kit don't fit them. Hopefully, I can get some O-rings tomorrow. I know it's unlikely but I need the car mobile on Monday.
