Today I had my first failure in 737NGX. I was parked at gate and just before the pushback I turned on electric hydraulic pumps A and B. The low pressure light didn't go away and also both overheat lights on A and B showed up. Hydraulic pressure was 20 psi instead of the normal 3000 psi. I turned off the pumps and waited for some time in case the temperature may drop and lights can go away but no joy. Meantime I examined the qrh (section 13.2) but i couldn't find info about when both lights are lit.So I cancelled the flight. Afterwards I restarted my flight from cold and dark cockpit (not from a saved file this time) and voila, hydraulics are working again as good as new.Any ideas?And by the way, thank you again PMDG, this is the first time i am cancelling a flight in my FS history because of some failure, and this is what i call realism :))
