First let me say that this is my first turbine and I am not an expert....
It took me a few starts to get the hang of it and part of my problem was with a bad pump. I have a JDE/Wren 54 that I bought used ...but only factory run. JDE does not use that pump anymore as they had problems with it leaking. I don't know if you have to set the "Pump Start Point" on yours but my start point on that pump was over 35. The Wren instructions said to discard the pump if it is higher than 35. The ramp light was blinking but I wasn't getting fuel right away. Thus my starter pack was running down as yours did (even though the temp was up)

I thought it needed more breaking in and ran it at low speed for a looonng time. Then it started to leak so I ordered a pump from Moore's. Even though this new one has a speed 400 motor instead of a 380, my start point went down to 18!! I did a breakin on it and the start point went down to 13, but it took a few seconds to actually start pumping. It starts reliably at 18 so I left it there. I did the break in under water to flush away the carbon. Now even at full speed there are no sparks or arcing in the motor.

Another thing to check is the thermocouple. Make sure it is in the right position to read the temperature.
