sr71hjason,
This is really weird and I'm at a loss for any suggestions-maybe Bob P. can chime in here. The tightness of the glowplug should have nothing to do with the EGT probe. What was the EGT on the data terminal with the glowplug loosened? It should read the ambient air temp in degrees C, or somewhere about 30-35C. With ignition from gas, it should climb to about 300-500 C depending on the depth of the probe into the tailcone. The RPM normally spools up to the set idle or about 55K. On some versions of the ECU the RPM may climb to the max, 155K, in teaching the ECU the specific engine parameters. This is all part of the ramping phase-upon completion the data terminal should indicate a "Running" condition when the RPM is controlled by the INC/DEC buttons or the transmitter if under RC. It is OK to remove the fuel solenoid if you suspect that it is faulty. However the ECU may not command a shutdown upon loss of RC signal as required by AMA turbine regs. I'd contact Bob P for his advice on all this. I have many years of experience with RAM turbines and this is all new to me. Good luck and let us know what happens.
