Complete cycle from start up to the fault and then shutdown and cooling.
'Pump limit reached' happens at 4 minutes.
I don't have additional Ts or valve to create the bypass. I'm very doubtful its the solenoid as on the first flight I did get full throttle for a while before the flame-out. Still think I've got a duff pump.
Worth swapping the solenoids around?
