Can anyone give me some help with my JJ1400.

I have never been able to start this turbine. The motor was returned to JJ and returned servicable, laterly the FADEC was returned and a new one received back

I now have a new FADEC, new solenoids, wiring well and truly separated and gas flow to the motor. The plug ( I have tried many plugs) is good as is battery voltages. Cables all connected correctly. The motor should surly wind up for longer than 2 seconds!

Today I tried once again ( with the new FADEC) to start the motor and still it cuts out after a 1 to 2 second wind up, there is no ignition, gas is flowing to the turbine and glow plug is hot. The motor makes 3 attempts to start before time out, each attempt only winds the motor for 1 to 2 seconds.

On the Data Terminal the ambient is 24c but when I advance the throttle to max open then closed for the start the rpm reads 64000 and as soon as the motor starts to turn the reading is normal. It winds up to an indicated 14000 then runs down, during the wind down the rpm indications fluctuate between 115000 and 24000 and continue to fluctuate when the turbine has stopped.

Is there a way I can check to see if the glow plug is sited correctly in the combustion chamber?

I am now desperate, months of work trying to get this thing to fire up and no flying.

Please help!
